Non Technical Summary
The food system is defined as the network of farmers, ranchers, processors, distributors, buyers and consumers that produce, trade, manufacture and consume food. Historically, Florida's food system was designed to leverage our seasonal advantage in the fresh produce market nationally and internationally. Florida's food systems operate at different scales: community, state, interstate and international, but this project will focus only on the community and state scales. Florida consumers and buyers are socially and economically diverse. Florida is the third most populous state in the nation, claiming over 19 million permanent residents and 84 million visitors in the state annually. However, over four million Floridians are considered food insecure, meaning that for 16.4% of adults and 25% of children, nutritious food is not available (food deserts) and/or not affordable. The population density is over 350 persons per square mile, much greater than the national average (87 persons per square mile). Development limits productive and affordable land that can be used for food production, and there are many competing demands on our natural resources. The bulk of agricultural production is produced by large farms (those having $1M or more in annual sales as defined by the USDA) that typically export commodities out of state. These large farms account for 3% of the total farms in the state. On the other hand, more than 90% of Florida's 47,500 farms are small farms, or those farms reporting gross annual sales of $250,000 or less according to the USDA. Most revenue from small farms is generated by direct to consumer sales. However, many of Florida's citizens lack opportunities to purchase fresh, nutritious food directly from a farmer, and many more lack that access from any retail outlet in their communities. Food desserts force citizens to make food choices that do not meet their nutritional needs. The large sector of small farm operators in Florida needs to be supported by research and outreach on market access and distribution strategies to enable them to contribute to Florida's food needs to the fullest extent possible. In response to current demand from consumers for local food and the state's lack of infrastructure available to process, pack and distribute food from small and medium sized farms to other outlets in the state, a significant number of new initiatives and brick and mortar businesses have established operations to take advantage of these economic and social/cultural opportunities. Additional opportunities exist as a result of the expansion of the national initiative Let's Move and popular interest in sourcing local food for cafeterias in Florida's 3,800 K-12 schools. Schools provide lunch and sometimes breakfast and afterschool snacks for over 3 million children a year. School food authorities maintain meticulous purchasing records and are an excellent opportunity to measure increases in local food purchases. At its heart, a food system cannot exist without farmers. Farms need to be profitable, food needs to be safe, and production practices need to conserve natural resources. Florida's numerous lakes and natural springs are a significant draw for tourists, and water quality and water demand are considered by the Florida public to be primary concerns. Florida farms are predominantly located on sandy soils with low fertility and fast water drainage. Because vegetables require 60-90 days to harvest, this relatively short period allows farmers to have three cropping cycles for each unit of land farmed. Extensive tillage is used to incorporate fertilizer, cultivate weeds, and incorporate remaining plant tissue after harvest. There is considerable interest in reducing tillage, reducing agricultural water, and minimizing off-farm inputs. Cover crops, or non-income producing crops planted to benefit the biological and ecological components of a farming system are an important tool used by farmers to conserve natural resources because the presence of living plant material keeps soil covered and in place during the hot, rainy summer, or cold winters when no income crop is present, and they can offset the following crop's fertilizer nitrogen requirement when legume species are utilized. In this regard, this project seeks to accomplish two primary goals: 1) Increase in-state consumption of specialty crops produced in Florida; and 2) Increase the rate of adoption of best management practices for soil and water conservation among certified organic and conventional specialty crop farms. Methodology for food systems efforts includes a census of current distribution and processing facilities and initiatives, an evaluation of farmer and buyer interest in new market channels including farm to school, a strategic plan for the development of Florida's food system, and development and dissemination of food safety best practices to school and community gardens. Methodology for farming systems efforts includes field experiments of replicated treatments utilizing factorial and systems designs that explore options to reduce tillage and off-farm inputs and increase soil health, and a decision support tool for farmers to guide them to make the best decisions for crop rotations that include cover crops. Expected outcomes include but are not limited to increased access of specialty crops to Florida consumers, reduced economic risk for participating farmers, statewide strategic plan for specialty crop food systems, a reduction of off-farm inputs, adoption of resource conserving practices, and improved cash flow for farmers.

Goals / Objectives
The objectives of this work over the next five years are to:Production and Distribution Increase market penetration of Florida food products and Florida food systems among institutional terminal outlets including Farm to School networks, hospitals, and other similar institutions that serve the general public by 15% over the next five years in at least one Florida county.Increase the number of processing and distribution outlets for fresh market and/or value-added products produced and sold in Florida in select communities that are designated as high impact communities by the Florida Department of Agriculture and Consumer Services by at least 10%.DiversificationAssess product availability, farmers' willingness to participate in new models of distribution and processing, and describe potential models of regional distribution and processing facilities for farm to school markets.Food Safety Develop and deliver training materials and programs to farm, community garden, and school garden operators as well as those clientele who are affiliated with direct to consumer markets (such as farmer's market managers) (50 participants a year) based on research findings and consistent with food safety legislation to increase knowledge of risk points in the farming system and methods to mitigate those points, new and/or alternative processors, products, and practices to enhance competitiveness and to maintain the viability of their operations.Increase adoption of food safety best management practices among schools, community gardens and farmers markets leading to 90% of entities in compliance with food safety legislation at the federal and state levels.Sustainable/Organic HorticultureIdentify best management practices for cover crop integration in sub-tropical and tropical vegetable systems including species selection, placement in crop rotation, and methods of planting and termination in a series of field trials in both certified organic and not-certified systems.Describe benefits and risks of cover crop integration in sub-tropical and tropical farming systems, including but not limited to potential increases in biological diversity, as tools for IPM programs, tools to mitigate water loss to evaporation, reduce soil temperature fluctuations, improve soil health, additional labor and input costs, and as potential reservoirs of pathogens, insects, nematodes, and weeds.Develop a cover crop decision support system or "learning tool" that integrates 1) enterprise budgets representing cover cropping costs and returns and 2) the soil health and water-related impacts of cover crops for a variety of different production systems. Publish the learning tool, make it available to farmers, and evaluate the tool's usefulness to farmers.Reduce expenditures for off-farm inputs including but not limited to fuel, nitrogen fertilizer, water, and pesticides by 20% or greater while maintaining crop quality and yield in systems that have adopted the practices recommended based on research findings from this program.
Project Methods
Food SystemsAssessment of Product Availability: To assess potential product availability, calculations of commodity yield averages and harvest windows for each desired commodity will be conducted within the state of Florida as well as at a county level. These data are readily available from the Florida Agricultural Statistics Service but are not reported in a format that would be useful to this team. Product availability data will be further integrated into demographic census data to estimate local demand.Evaluate Farmer and Buyer Commitment: We will employ a more personal approach when appropriate and utilize focus groups, telephone interviews, and face-to-face visits on farms to identify farmers' perceptions of barriers, benefits, and extent that they are willing to participate in new distribution/processing models.Increase the Number of Retail Outlets: Advances in GIS mapping and availability of socioeconomic data have allowed state and federal agencies to identify areas in need of nutritious food or increased access to food. High impact areas are those areas identified by the Florida Department of Agriculture as having the likelihood of a high rate of return on investment of programs to increase food access, based on income, availability of retail outlets, distance of housing to markets, and other factors. Specific activities can include but are not limited to establishing mobile fresh fruit and vegetable markets, new farmers markets, and community gardens.Feasibility Study of Farm to School Procurement: Buyers, including consumers, processors, institutions (schools, hospitals, prisons) and distributors will be asked to share purchasing history with this team. Indirectly, farmer commitment will be quantified based on the volume and diversity of Florida commodities sourced by buyers. School food service, independent grocers, farmers markets, and large-small scale processors are groups of buyers we are particularly interested in because of the availability of data and the transparency of trade as viewed by the general public. With baseline data gathered at the beginning of the period, we will monitor changes over time. The county scale was selected because many school food purchases are made with sufficient volume to receive competitive pricing and can supply the entire district (district = county), and county-level policies and regulations are well-integrated throughout the food system.Economic Impact: Typically, economic impact is measured in farm-level income or by sales at businesses within the area (farmer's markers, independent grocers), retained dollars in the system when re-spent locally, and employment increases. Because the economic data described here reflects ongoing work by current IFAS faculty, this team aims to focus on direct market channels (Farm to consumer).Census of Existing and Emerging Food Infrastructure: A statewide census of current and emerging capital investments and community initiatives will describe what models are already on the ground and working; successful initiatives could be opportunities for leveraging efforts and serve as a public commitment for supporting healthy communities. This information will be collected through telephone interviews and face to face conversations with county Extension directors, county economic development board members, and local industry leaders.Assessments and Recommendations for Improved Processing Capabilities for School Food Service: Nationally, there are excellent examples of successful farm to school food facilities. If the scale (number of meals served/day), functions (dry/wet/cold pack, wash/chop/flash frozen, etc.), services (co-pack, process, aggregate), and extent and quality of partnerships are relative to the organization's mission and community need, then the facility will likely be a success. For example, processing facilities that include a partnership of an institutional processor with a co-pack aggregator and "last mile" distribution system could be a logical choice for Florida. A single farmer could provide product to the partnership that would be utilized in multiple ways, maintaining the chain of in terms of food safety and traceability and increasing efficiency for all parties. This structure would also be more amendable to attracting small to mid-size operators interested in farm to school and other institutional networks. Fresh market products could be used to enhance school entrees as well as support the local food system and address food security in other ways as needed by the community. Volume limits could be put in place to reduce internal competition.In collaboration with the UF-IFAS Farm Food Safety Team, various methods will be examined to determine the most effective training approach, measured by knowledge gain, intent to adopt practices at the time of training, and subsequent confirmations of behavior change leading to adoption of practices. Methods include classroom, face to face training, in-field experiential learning and mock food safety audits. Considering that the Food Safety Modernization act is still several years away from being fully implemented, this work is expected to be ongoing throughout the duration of the project.Sustainable/Organic HorticultureThe primary objectives of these studies are to restore or improve soil health and in particular the capacity of the soil to cycle nutrients and water to crops. Multi-year field trials will be conducted on farm or on University of Florida research stations and will compare treatments to a farmer standard control. Designs for experiments will likely be complete block designs, depending on the hypothesis tested. For some trials, a systems approach to hypothesis testing will be utilized when the information sought is dependent upon multiple variables. For cover crop and nutrient management experiments, negative controls (grower standard) is typically the absence of a cover crop, but could be plastic mulch if the treatments involved plant-based surface residues. Treatments typical of this set of experiments include conventional tillage, reduced tillage, presence or absence of cover crop, cover crop species analysis, monoculture cover crop species verses species mixtures, planting rates and time of year, termination by mowing (with or without soil incorporation) or roller-crimping. Data collected includes: soil moisture, precipitation/irrigation rates, soil chemical properties including organic matter and nutrient content, physical properties including bulk density and water infiltration rates, cover crop C:N and biomass, residue remaining on the soil surface following cover crop termination and then throughout the following cropping season, pest density and diversity, and vegetable crop yield and quality.Cover Crop Decision Support System: To explore the soil health and economic benefits of cover cropping across time scales and management systems to improve system resilience, a variety of crop species, cover crop species, and farming systems will be utilized. For each experiment, soil type, cropping system, cover crop species, and methods of planting and termination will be defined and explored. Soil moisture, rainfall, soil organic matter, and soil nutrients, cover crop C:N and biomass, and management records will be monitored at each location to quantify the impacts of different cover crop management on soil water balance and nutrient cycling in organic as well as conventional specialty crop farming systems. Farmer practice will be compared to research findings and specific best practices will be defined based on quantitative data and practitioner experience. A web-based learning tool for cover crop decision that incorporates Enterprise Budgets, the Water Footprint tool http://agroclimate.org/tools/Water-Footprint/, the use of seasonal climate forecasts for cover crop management, and data from multiple, representative experimental sites.

Outputs
Target Audience:Food Systems and Food Safety: Farmers, brokers, distributors, aggregators, processors, buyers, consumers, policy makers, creditors, farmers market managers, county and city officials, state agencies responsible for food trade, processing and service activities. When schools are involved as buyers, there is an emphasis on those schools with 51% or greater participation in the National School Lunch program Organic/Sustainable Horticulture: Farmers, consumers, buyers, technical service providers and NRCS staff in particular, community and school gardens leads and practitioners Changes/Problems:Over the life of the project, the greatest challenge was making progress with market channel development for local food systems. Objective 1 aimed to increase the access and affordability of food in low-income areas, including schools with a 51% or greater participation in the National School Lunch program. When this project was approved in 2014, I had formal responsibility and funding support for Farm to School network development andprocurement. Objective 1 goals were explicitly written to mirror plans of work from these two projects. In 2016, due to administrative changes, my funding for the program ended. I continued to work towards Objective one goals, but my scope of work has declined over the years as projects came to completion to the advisory role I have now. As such, accomplishments for that objective are primarily during 2015-2017. In 2018 and 2019, I mentored students, served as a guest speaker in extension education programs, and provided guidance to the team. Farm to school local procurement has increased every year, according to our state department of agriculture, and I'd like to think I had some small role in that. However, I do not anticipate formally renewing these objectives in future HATCH proposals. What opportunities for training and professional development has the project provided?Two statewide presentations were given: Organic Vegetable Gardening was a one-hour video conference to home gardeners as part of the Victory Garden 2020 series, and a presentation to faculty, agents, and service providers on cover crops and BMPs as part of the statewide BMP educational series to 35 and 73 attendees, respectively.One in-service training to 39 participants. How have the results been disseminated to communities of interest?Results have been disseminated face to face grower meetings at the county and multi-county level, small group work with agents and faculty, direct one on one contact with clients, farm visits, and through trained agents. Fact sheets, Facebook posts, and program websites were also used. What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? Food Systems. One of the ways Florida farmers can increase market penetration of their products is to ensure they have sufficient volume to meet the demands of processors and buyers. Carrots are an emerging industry in Florida, and Florida producers are poised to supply a portion of the eastern US market if demand remains strong. Several other emerging enterprises such as hops, industrial hemp, specialty pumpkin, and artichoke are efforts led by other faculty. To bring the researchers and agents together to evaluate these opportunities and design programming needed for farmers' success, the university led a 1.5-day In-Service Training - Emerging Enterprises. I co-lead the design and implementation of an educational track, Organic Enterprises, and Transition. Thirty-nine participants were present in this session. I provided two presentations in collaboration with agents, including Organic Carrot Production in Florida and Organic Transitions. I led a 12-member team on an internal grant proposal submission to continue research and extension efforts on organic carrot production and organic transition. The decision will be announced in spring. I participated in the FFAR's Smart Urban Food Systems Summit in New York City in October and led an article to describe my experience with two other UF participants. In late 2019, I led a proposal team (for January 2020 submission to the Florida Specialty Crop Block grant program) to address barriers to accessible processing for North Central Florida farmers by connecting them with existing farm-to-institution networks. This project aims to increase sales of value-added specialty crops from local farms and accelerate food system innovation. Pilot participants include food buyers from one state institution and two county school districts, two processors, a non-profit and six specialty crop farmers. This team has extensive experience in farm to institution food service, specialty crop production and processing, farm food safety, and program evaluation, and will provide strategic and tactical support for participants. Research, extension, and education activities will be employed to describe institutional local food purchasing habits, design and assess new processing strategies, document storage and distribution requirements of institutional food buyers, processors, and small-scale distributors, and establish a group GAP framework for project participants. Cover Crop Best Practices. I contributed to the design and implementation of The Cover Crops and Soil Health Field Day, conducted in February in north Florida. The program included formal presentations, discussion, farmer keynote, sponsored lunch, and a field tour highlighting innovative cover crop practices. I gave a presentation on cover crop mixtures and designed the program evaluation. There were 53 responses out of 65 attendees. Twenty eight percent of farmers reported they had grown cover crops for ten or more years, 21% had grown them for 3-4 years, while three groups of 17% each had either grown them for 5-9 years, 1-2 years or had never grown a cover crop. Among all respondents, the top problems identified as a "Very Serious Problem" were lack of knowledge (21%) and timing of planting (18%). The top problems identified as a "Moderate Problem" were annual cost (48%), equipment (44%), lack of knowledge (37%), labor (34%), and interference with cash crop (32%). Most farmers found all presentations helpful, as a range of 65 to 92% indicated so. Ninety-five percent (95%, N 44) stated that they were planning to make a management change because of the information shared that day. Of the twelve respondents who indicated that they had attended the cover crop workshop in in March 2018 (I presented at that program as well), three indicated that changes were made based on that workshop, including the types of cover crops used, the use of soil health sampling and adoption of cover crops. Cover Crop Risks and Benefits. In the 2017 National Cover Crop Survey, US farmers reported 15.5 million planted cover crop acres predominantly in Midwestern row crop systems, including corn and soy. However, this study captured very little information from farmers located in Florida, Puerto Rico, and the US Virgin Islands. To better understand the educational needs of farmers located in these areas, semi-structured interviews were conducted to document farmers' perceived barriers to cover crop adoption. Study methods were approved and granted Exempt status by the University of Florida's Institutional Review Board (IRB 201802091). Twenty-five farmers (Florida: n=14, Puerto Rico plus the US Virgin Islands: n=11) voluntarily participated in a one-hour face to face interview conducted at their farms. Farm size ranged from 1.5 to 5,000 acres, with the predominant systems being diversified vegetables (n=10) fruit and nut tree crops (n=6), peanuts, and cotton (n=5) and pastures (n=4). All the farmers interviewed had either used cover crops in the past or were currently using cover crops. The years of experience managing cover crops ranged from two to twenty-seven years. Farmers cited a variety of objectives for using cover crops, including preventing soil erosion (n=9), weed suppression (n=9), increasing soil health (n=7), and improving water conservation (n=5). Data from these in-depth farmer interviews are critical to understanding cover crop use and adoption dynamics among farmers historically underrepresented in national and regional cover crop surveys. Cover Crop Decision Tool. While we have made progress on the cover crop decision tool, it remains a work in progress. At this time, cover crop information sheets are in draft form, with input from farmers and agents, with information about planting methods, species selection, crop rotation, and other essential management recommendations. In addition, five fact sheets are in draft form and will be published to the university fact sheet library and linked to the Southern Cover Crop Council's website upon completion. Reduce Off-farm Inputs. A graduate student has completed two previously described studies on cultural pest management of organic peach, on the effect of bagging young peaches with an opaque white bag, and a second study evaluating the effect of colored films on anthocyanin expression in peach. Findings from the first study are as follows. Protective bags appeared to delay maturity, as flesh resistance and chlorophyll concentration increased more than 127% compared to unbagged fruit. Bags reduced mechanical injury by almost 4%, reduced fruit fly injury by a factor of five, and reduced scab-like lesions by a factor of nine. Scab-like injury severity was similar at lower injury levels, but bags reduced the incidence of severe injury by 6.5% (greater than 20 lesions per fruit). Bagging reduced fruit brown rot (Monilinia fructicola) at harvest and seven days after harvest; unbagged fruit were 2 and 3.5 times more likely to have rot at harvest and seven days after harvest, respectively. Fruit bags did not affect yield, size, total soluble solids, pH, skin lightness, skin hue angle, and all color measurements of flesh color. Overall, the canopy cardinal quadrant location had minimal effect on fruit quality. These results demonstrate that bagging fruit had minimal effects on fruit quality and protects fruit against various pests and diseases. Broad adoption of this technology is highly dependent on available labor, market demands, and profitability, but may be suitable for producers utilizing direct-to-consumer market channels.

In support of farmers selling direct to consumers in urban and rural areas throughout Florida, the Florida Direct Marketing Handbook, first released in 2018, continues to be very popular among our Extension agents. Agents purchase in bulk from the Extension Bookstore to distribute during programs and refer to as a handbook in one-on-one counseling. In 2019, we printed an additional 1,000 books. The team was recognized for the guide this year with the following (additional from 2018) awards: American Society of Horticultural Sciences National Blue Ribbon Extension Materials Award and Southern Region winner, and National Association of County Agricultural Agents Extension Award Finalist. Agents have asked for slide presentations to complement the text, and that has been slated for 2020's plan of work. Food Safety. Invited speaker to the Florida SNAP-Ed Annual Meeting. Provided one hour of instruction to 24 nutrition educators on Food Labelling and Product Claims. Sustainable/Organic Horticulture. In 2019 I was a mentor for an undergraduate honors student. The program at UF requires students to conduct a research project and write a final paper. I met with the student monthly, and sometimes more frequently to provide instruction and guidance. The student identified and defined her project area did the research, and successfully submitted her final project in December 2019. She presented her work on a poster at the Southern Region ASHS, was awarded the best poster overall, and received $300. This student is now in law school. I provided face to face instruction to approximately 100 undergraduate students on Organic Fruit Production for a general education class (1CR). This is a class I am invited to teach every year. In addition, I recorded an online version for distance education under the direction of the course instructor. I used this opportunity to give my doctoral student some teaching experience, and he presented part of the lesson. Hosted one high school student in my laboratory who assisted with organic carrot research, specifically, taking qualitative data (weight, length, USDA market grade) and analyzing for carotenoid concentration. The student learned how to set up spreadsheets, collect data accurately and ethically, and interpret statistical figures to draw conclusions in his own words. The student was directly mentored by my doctoral student to provide him with a mentoring experience. One hourly undergraduate student from Agricultural Education supported my program overall by contributing to written and visual (graphic arts) educational material. I mentored her through the style and design of the Direct Marketing Guide; she completed layouts, helped edit, contributed style and design ideas, and is included on all awards received for this guide. How have the results been disseminated to communities of interest? A major revision was completed on the most popular extension fact sheet at UF: Organic Vegetable Gardening and the Florida Vegetable Gardening Guide (85,000 downloads in 2019), minor revisions and updates were completed on the fact sheets Organic Vegetable Gardening (lead), Economics of the Organic Industry in Florida, Growing Bell Peppers Under Open Shade Structures, and Transitioning to Organic using Conservation Tillage. A graduate student presented his organic peach research to 75 producers at the Stone Fruit Field Day. I presented a summary of organic carrot nitrogen management to 45 producers and state agency representatives at the Twilight Field Day. Presented an update on the work of the Southern Cover Crop Council to 40 row crop producers at the Soil Health and Cover Crop Field Day. Created approximately 200 posts to the Small Farms and Alternative Enterprises Facebook page, for a total organic reach of 65,561 (2,200 followers). The sum of field consultations, office consultations, group learning participants, telephone and email consultations was 458 contacts. What do you plan to do during the next reporting period to accomplish the goals?This project ends February, 2020. In the final six months, we aim to finalize research manuscripts from projects that have been ongoing, seek additional funding to continue the work, and begin a new HATCH project.

Impacts
What was accomplished under these goals? Florida SNAP-Ed Farm to School. During 2019, I phased out of my role as a faculty advisor toten Regional Farm to School Coordinators (now referred to as Food Systems Specialists) due to time constraints and the need to prioritize publications. One letter of recommendation was written for a full-time staff member that resulted in her successful hire to a full-time SNAP-Ed coordinator for the state of Ohio. I continued to provide food safety educational training, provided crop production recommendations, and helped troubleshoot production issues for SNAP-Ed staff and UF/IFAS Extension agents working in the farm so school programming as needed. Florida school districts purchased $7.6 million worth of Florida specialty crops during the 2018-2019 school year through competitive contracts (6.7 million pounds) (FDACS, 2019). An additional 544,000 pounds of produce worth $826,000 were purchased from Florida farmers though the USDA's Department of Defense Fresh Fruit and Vegetable Program (DoD Fresh). Purchases of Florida specialty crops through the DoD Fresh program increased 21% in the 2017-2018 school year, and 25% in the 2018-2019 school year (FDACS, 2019). Food Safety. A summary of our work was presented by the project's PI at the International Assoc. of Food Protection's annual meeting. Orchard Floor Management with Cover Crops. This new project is intended to improve the management and adoption of cover crops in Florida's tree fruit, including citrus. The citrus industry has been declining since the introduction of the disease citrus greening (Huanglongbing or HLB) in 2005. In Florida, 595 farms (64,000 acres) abandoned citrus from 2012 to 2017, leaving 474,540 acres currently in production (USDA NASS, 2019). Most citrus is produced on sandy soil (Entisols) characterized by rapid water infiltration and low nutrient retention. Trees require ample fertilizer and irrigation for a profitable crop. Huanglongbing infected trees also require 57%, 15%, 22%, 11%, 190%, and 90% more K, Mg, Mn, Zn, Cu, and B, respectively, to remain above previously established critical threshold concentrations (Schumann et al., 2019). HLB trees also have a small root system (Morgan et al. 2007; Johnson et al., 2014) that prevents efficient nutrient and water uptake. Applying additional soil-applied nutrients will leach under current management plans (Morgan et al. 2007), but improving the soil chemical, biological, and physical properties may increase plant-available nutrients. Cover crops have the potential to increase soil health and nutrients by increasing the soil water residence time (reduced leaching) and nutrients (Granatstein and Sanchez, 2009). Cover crops grown with citrus have increased soil nitrogen availability and reduced weed density and diversity (Linares et al., 2010), but research has not kept pace with grower practices, including new species and cultivation techniques used by innovative farmers. Improving citrus production in central Florida counties that collectively contain over 26% of the state acreage will benefit Florida's citrus industry and economy. We planned a small study at a research station in conventional citrus (0.3 acres) to quantify the effect of cover crops on nutrient cycling, water use efficiency, and weed management. Treatments include full tillage, strip tillage with direct-seeded cover crops compared to a control of native vegetation, and treatments are arranged in an RCBD. Cover crops were planted in November, and three soil moisture probes are installed in representative plots to collect soil moisture data every six inches to 42 inches deep. Cover crops will be terminated in spring, and summer cover crops will be planted immediately after, followed by winter cover crops at the end of 2020. The trial will end in the spring of 2021. Preliminary data will be used to secure a multi-year grant to continue the work. Cover Crop Educational Materials. 2019 activities for our Southern SARE project included an approved and Exempt IRB #201802091, completed 29 interviews of farmers in Puerto Rico, St. Croix USVI and Florida, presented preliminary data at the Southern Region ASHS and have an abstract accepted at the National ASHS meeting in August. Cover Crop Information Networks. In 2019, our team composed of faculty representing the US regional cover crop councils and others (100 scientists from 35 institutions) was awarded an AFRI-SAS CAP grant to enhance the effectiveness of cover crop conservation tillage systems in corn, soybeans, and cotton. We will investigate the impacts of cover crops on chemical and biological cycles and their influence on crop performance, water, and nitrogen availability and use efficiencies, and pests, diseases, and weeds. My role as a co-PI on that project will be to conduct research on three north Florida farms using real-time data flow, edge and cloud-based platforms, decision support tools, and on-farm monitoring systems. Data will be used to improve cover crop recommendations. Nitrogen Management in Organic Carrot. Co-PI FDACS Office of Ag and Water Policy grant Organic and Conventional BMPs for Carrot in Northeast Florida. No formal recommendations for organic carrot nitrogen fertilization have been published for Florida producers. Organic nitrogen inputs require biological nitrogen fixation and mineralization prior to plant uptake and are therefore inherently different conventional fertilizers (salts). Completed research to develop nitrogen fertilization recommendations for organic carrot and this paper is now in an advanced draft form, formatted for the journal HortScience. This work was presented at the Southern Region ASHS meeting in August.

Outputs
Target Audience:Food Systems and Food Safety: Farmers, brokers, distributors, aggregators, processors, buyers, consumers, policy makers, creditors, farmers market managers, county and city officials, state agencies responsible for food trade, processing and service activities. When schools are involved as buyers, there is an emphasis on those schools with 51% or greater participation in the National School Lunch program Organic/Sustainable Horticulture: Farmers, consumers, buyers, technical service providers and NRCS staff in particular, community and school gardens leads and practitioners Changes/Problems:Objective 1 aimed to increase the access and affordability of food in low-income areas including schools with a 51% or greater participation in the National School Lunch program. When this HATCH proposal was approved in 2014, I had formal responsibility and funding support for Farm to School network development including procurement and was funded as PI under contract from FDACS as well as a co-PI for the Family Nutrition Program, Florida SNAP-Ed. Objective 1 goals were written specifically to mirror plans of work from these two projects. In 2016, the agency that serves as the fiscal agent for implementing SNAP-Ed funds initiated administrative changes and consequentially my funding for that program ended. I continued to work towards Objective 1 goals but my scope of work has declined over the years as projects came to completion to the advisory role I have now. As such, institution workload reporting was submitted for 2013-2017 only, and I do not anticipate formally renewing these objectives in future HATCH proposals. What opportunities for training and professional development has the project provided?Food Systems 1. The PSEChange.org website was completed and published. 2. The UF/IFAS Small Farms and Alternative Enterprises website was completely overhauled with new content (38 pages) and built upon a T4 platform. The website had its soft launch in November 2018. Last year, the site received 998,000 visits. Food Safety 3. Produce Safety Alliance Training to 75 participants in 4 training events. Each training was a full day (7 hours). Sustainable/Organic Horticulture 4. Stone Fruit Field Day, Citra, FL May 29, 2018. A farmer field day was held at the UF/OFAS Plant Science Research and Education Unit near Citra, FL on May 29, 2018. PI was invited to give an oral presentation titled Cover Crop Options for Fruit Orchards. UF's Stone Fruit Extension Specialist and Lake County's Extension Director organized the field day. Among the 128 or so attendees were current and some prospective farmers, industry representatives, technical service providers, researchers and agency staff. A post-program evaluation was administered and while response was quite low (n=19), 42% of respondents cited Treadwell's Cover Crop talk as "Most Useful" on a 5-pt scale from Least to Most Useful. Peach Rootstock Issues and Progress was favored by 63% of respondents, and the field plot tour was favored by 53% of respondents. 5. Carrot Twilight Field Day, Live Oak, FL. March. Presented preliminary findings from organic nitrogen management carrot study to more than 50 producers, agency staff and industry representatives. 6. Soil Health for Organic Farmers Session. Organic Food and Farming Summit Gainesville, FL. Led a 90-minute session for 35 organic farmers to increase their knowledge of soil characteristics and best practices for managing soil optimally. Hands-on, demonstration, and formal instruction. How have the results been disseminated to communities of interest?Popular press, face-to-face training, video, slide presentations, social media, Extension fact sheets, peer-reviewed journal article. What do you plan to do during the next reporting period to accomplish the goals?This project ends February 2019. A new HATCH proposal is underway.

Impacts
What was accomplished under these goals? 1. Improving Production, Distribution and Diversification in Florida's Food System- Florida SNAP-Ed Farm to School. Served as a faculty advisor toten Regional Farm to School Coordinators (now referred to as Food Systems Specialists) including program planning, development, and mentoring through email and phone correspondence and face-to-face meetings. Letters of recommendation were written for 3 full time staff members resulting in the following: acceptance into graduate school at University of Vermont's Food Systems program (staffer will conduct this online while continuing her position), successful hire to a full time tenure-accruing UF/IFAS 4H Extension position in the staffer's home county, and a UF/IFAS Superior Accomplishment Award for the team's state coordinator. This year, I provided food safety educational training and financial support of food safety educational training to staff, provided crop production recommendations, and helped trouble shoot administrative, human resource, and production issues as needed. In 2018, Alachua County School District's Farm to School Coordinator led a program that resulted in approximately 24% of produce consumed in Alachua County's school cafeterias sourced from Florida farmers. Florida SNAP-Ed staff (2 FTE) provided support for these achievements with additional support provided by other members of the F2SC team (State Coordinator for SNAP-Ed Farm to School and Community team and Northeast Regional Food Systems Coordinator) with support from this faculty member as described above. Regional Nutrition Education and Obesity Prevention Centers of Excellence. Co-PI ona multi-state project funded by the USDA-FNS sought to enhance the capacity of SNAP-Ed and EFNEP networks to implement and evaluation policy, systems and environmental (PSE) approaches and to strengthen the effectiveness of PSE approaches. A website and online training resource was developed to provide a consistent web training and resource site for SNAP-Ed and EFNEP PSE implementation. My work includes three videos on best practices for school and community gardens. The project was completed in 2018. Florida Direct Marketing Handbook. Approximately 150 farmer's markets are registered in the Florida Department of Agriculture and Consumer Services community farmers markets listing, and 32 of these markets in 15 counties work in partnership with SNAP and WIC recipients. A statewide effort to create a reference handbook for these farmers selling direct to consumers was led by myself and a co-leader of the UF/IFAS Small Farms and Alternative Enterprises program. Content was written by state and county Extension faculty, and reviewed by editors and staff from state agencies. The 88-page full color guide was published this year with an initial printing of 500 copies and distributed to agents throughout the state. It was awarded a Blue Ribbon Extension Communication Award by Southern Region American Society for Horticultural Sciences. SCRI Proposal. This past year I served as a co-PI on a multi-state SCRI submission titled Enhancing the Productivity, Equity, and Sustainability of Specialty Crop Food Systems (led by UF/IFAS). My proposed role was to work with farmers and food system intermediaries to identify needs and implement solutions to local food infrastructure limitations that hinder development of farm to consumer market channels, particularly for food insecure residents in two Florida counties. This proposal is under consideration. Sarasota County School District Farm to School Procurement. A doctoral student (under my direction as co-Chair and financial sponsor) conducted an extensive analysis of county school food purchasing history to determine the feasibility and economic assessment of a farm to school procurement system. Investigations included farmer interviews to assess barriers and opportunities of participating in farm to school procurement (funded by a graduate student Southern Region SARE award), completion of an economic impact assessment of local food procurement (published in 2018 in JAFSCD, see publications). A second paper reporting the outcomes of a feasibility analysis of farmer cooperatives to support farm to school procurement is in preparation. 2. Food Safety Produce Food Safety Training. Provided instruction at two Produce Safety Alliance Trainings. In addition, I am a co-PI on a USDA grant to develop and deliver educational materials for specialty crop producers. Our team has focused on delivering the programs in production and processing areas using a hands-on format where participants learn how to apply the Produce Safety Rule in their operation. An evaluation instrument was designed and utilized. All the Responses (n=15) were entered into Qualtrics, tabulated and then analyzed through a Paired Sample T-test using IBM ISPSS Version 25. Mean pre-test scores in percentage were 35.94, while mean post-test scores were 81.5. All 15 participants increased their knowledge with an average gain of 8.2 points. The T-test result indicated that this difference was statistically significant. Two additional trainings are scheduled for 2019. Online School Garden Food Safety Training. Revisions were made to seven modules of an on-line training for school garden food safety. The Florida Department of Agriculture and Consumer Services will host this training. It is expected that all school gardens receiving financial support from FDACS have a garden lead onsite that has successfully completed the training and will serve as the food safety point person for the school. Three extension fact sheets are in preparation by project co-PIs and are designed to complement the online training. 3. Sustainable/Organic Horticulture Organic Peach Production. Co-PI (Florida lead) for the four-year USDA OREI grant "Evaluating Paper Bags for Pest Management in Organic Peaches". I recruited a graduate student (PhD) and farmer cooperator for the research. The first year of research completed on certified organic peach orchard in Lake County, Florida. Yield, fruit quality, postharvest quality, disease identification and severity, and insect density identification to family (via traps) comprise the dataset. The student presented preliminary findings at the American Society for Horticultural Sciences in August 2018, and an Extension fact sheet was published on eXtension in the Organic Agriculture Resource Area. Cover Crop Educational Materials. This year a new project was initiated, funded by Southern SARE to evaluate farmer opinions of risks and benefits of cover crops in Florida, Puerto Rico and the US Virgin Islands and to develop educational materials to support the adoption of cover crops in food and fiber production systems. An IRB for farmer evaluation was submitted and approved. Cover Crop Decision Tool. The Southern Cover Crop Council was formed in December 2017, and I currently serve as the Council's Co-Chair of the Education and Communication Committee. In this capacity, I have assisted with the development of the decision support tool by reviewing materials and assisting with the design and development of the council website. I also lead the social media effort. The decision support tool is published on www.southerncovercrops.org. Nitrogen Management in Organic Carrot. Co-PI FDACS Office of Ag and Water Policy grant Organic and Conventional BMPs for Carrot in Northeast Florida to developnitrogen recommendations for organic carro tin Florida. Completed second year of research to develop nitrogen fertilization recommendations for organic carrot. The experimental design is a randomized complete block with five nitrogen rates ranging from 168 kg ha-1 to 393 kg ha-1; treatments are replicated four times. Data include yield, root quality, nitrogen-partitioning (root/shoot) at harvest, and soil nitrogen. Preliminary finds were presented at the Crop Science Society's Annual International Meeting in November.

Target Audience:Food Systems: Farmers, brokers, distributors, aggregators, processors, buyers, consumers, policy makers, creditors, farmers market managers, county and city officials, state agencies responsible for food trade, processing and service activities. When schools are involved as buyers, there is an emphasis on those schools with 51% or greater participation in the National School Lunch program Organic/Sustainable Horticulture: Farmers, consumers, buyers, technical service providers and NRCS staff in particular, community and school gardeners Changes/Problems:Convincing growers to attend and follow food safety trainings and best practices continues to be a vexing challenge. We have been successful in recruiting our highly visible farmers to participate and adopt food safety practices, but there are many more in the state that still need training. Disappointingly, attempts to engage farmers to attend farm food safety training through farmers' market networks has been met with a degree of contempt. Farmers and market managers do not agree with our team's encouragement and concern for possible libel should something happen down the road. We were successful at meeting our goals in our FDACS Specialty Crop Block grant, but recognize that training these farmers is still our responsibility at the moment, in the absence of other venues or partners. We will continue our efforts to strategize about effective communication strategies and will try new approaches to reach the segments of our clientele that for now seem unwilling to participate in farm food safety training. No other problems or challenges to report in terms of fulfilling objectives in competitive awards. What opportunities for training and professional development has the project provided?1. Improving Production, Distribution and Diversification in Florida's Food System Two invited presentations were delivered to the beneficiaries listed for the production and distribution objectives. Developed specifically for an audience of farmers and chefs in Florida's panhandle, the 30 minute presentation titled "Hot Topics in Food and Farming" reviewed green labels including the National Organic Program, discussed genetically modified crops and their perceptions (and misperceptions) by the buying public, and proposed a framework for discussing emotionally charged topics in our food system. Slide presentation followed by discussion. May 20, 2016. Participants = 19. UF/IFAS Extension Escambia County, Cantonment, FL. A 15 minute presentation to farmers and local decision makers interested in expanding local food economies titled "Fruit and Vegetable Marketing" was one of eleven presentations at the day long program UF/IFAS Tampa Bay Cottage Industry Expo. Participants = 45. Wesley Chapel, FL. July 30, 2016. 2.

Food Safety Face to face conversations, informally as well as in a formal program, oral presentations, visual aids, handouts, newsletter articles, blogs. 3. Sustainable/Organic Horticulture In addition to the methods previously described, program results have been disseminated in the classroom to graduate and undergraduate students during invited guest lectures including FRC 1010 ("Organic Fruit Production" Growing Fruit for Fun and Profit, 1 CR elective, enrollment = 275), as well as student groups ("The Science of Sustainable Agriculture" Sigma Alpha n=50). What do you plan to do during the next reporting period to accomplish the goals?1. Improving Production, Distribution and Diversification in Florida's Food System A full proposal was submitted to FDACS' Specialty Crop Block Grant Program to request funding to develop educational content based on research for small farm operators, including revisions to the specialty crop portion of the website. Assist my recent PhD graduate in publishing his papers from his dissertation. Continue to develop relationships and look for funding opportunities to address objectives. Complete the competency based PSE web-based training for SNAP-Ed and EFNEP networks. 2. Food Safety I will participate in the Train the Trainer course: Produce Safety Alliance's Produce Food Safety Training scheduled for early 2017. Four grower PSA trainings are planned thus far for 2017. Continue to mentor agents and as co-PI of the Southern Center grant facilitate opportunities for agent food safety training. 3. Sustainable/Organic Horticulture To advance the nitrogen use efficiency in organic vegetable production systems and reduce risk to groundwater quality, a proposal was submitted to FDACS Office of Agriculture and Water Policy to update best nitrogen management practices for organic carrot and conventional carrot from previous recommendations written 30+ years prior. The Southern Cover Crop Council board has prioritized the development of a cover crop decision tool, and we will begin working on that in 2017. I will seek external funding to assist with this development. Continue to mentor PhD student and refine his course of study in organic specialty crop systems.

Target Audience:Food Systems: Farmers, brokers, distributors, aggregators, processors, buyers, consumers, policy makers, creditors, farmers market managers, county and city officials, state agencies responsible for food trade, processing and service activities. When schools are involved as buyers, there is an emphasis on those schools with 51% or greater participation in the National School Lunch program Organic/Sustainable Horticulture: Farmers, consumers, buyers, technical service providers and NRCS staff in particular, community and school gardeners Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?Production and Distribution.The F2SC team supported local food procurement at all levels, from small-scale gardens to large-scale school food purchasing.Over 100 gardens were installed and maintained with 4,209 beneficiaries enjoying 80,811 active hours in the gardens.School gardens were designed with 85% having 4 of the 5 vegetable sub groups from the new meal pattern and produce was enjoyed as taste tests, in cafeteria lunches, and taken home to be eating with the family.Community gardens around the state covered around ½ acre and had the potential to produce enough food for 65 adults estimated to have a $33,106 retail value during the growing season. 881 or 21.0% of the schools in Florida purchased food from Florida farmers (a total of 409,744 pounds) as a result of direct actions made by the F2SC team.As a testament to the impact F2SC is creating in farm to school procurement, Beverly L. Girard Ph.D., M.B.A., R.D., Director of Sarasota Food Nutrition Services, said "We would not have been successful without Zach Glorioso (F2SC South Central DC)." Food Safety. In addition to the Build your own Farm Food Safety Manual classes, The Florida Small Farms Food Safety Implementation Team taught at several other meeting in July- December, 2015. These included: Local Foods Summit, September 20 in Gainesville, FL with 8 attendees for this session on training programs offered by this UF/IFAS team Florida Farmers Market Managers Food Safety Training, November 9 in Gainesville, Fl with 48 attendees for the session on Farm Food Safety GAPs and how UF/IFAs can help train farmers Watermelon Farmers Food Safety Update including HACCP and FSMA, December 1 in Gainesville, FL with 28 attendees. This session was organized by this team. Organic and Sustainable Horticulture. UF hosted a field day for farmers that attracted over 40 participants. The program included classroom style presentations, a farm tour, and activities in teh field designed to help farmers identify benefits of cover crops. How have the results been disseminated to communities of interest?Production and Distribution.The team used a variety of media outlets and face to face educational programs to communicate findings to stakeholders and the general public. Members of the F2SC team were honored with the 2015 Southern Region as well as National American Society for Horticultural Sciences-Outstanding Educational Materials Award during annual meetings in February and August. In addition, the F2SC team was also honored with a University of Florida Champions for Change Award for their contributions to improving the school and community food environments. Team members were interviewed, photographed, and/or mentioned in the media ten times for a variety of additional accomplishments. Each District Coordinator was awarded a competitive scholarships to attend farmer conferences and food safety and smarter lunchroom trainings valued at an estimated $2,474. Food Safety. Results are disseminated to farmers typically in face to face settings, although we do use social media and our team's webiste (Small Farms and ALternative Enterprises). Organic and Sustainable Horticulture. Results are shared during edcuational programs, our peer-reviewed electronic fact sheets, and on our Facebook page. I work with NRCS to communicate findings. i support NRCS nationally by idenitifying expert farmers to serve as mentors for others. I give guest lectures to undergraduate and graduate students. What do you plan to do during the next reporting period to accomplish the goals?Production and Distribution.The team used a variety of media outlets and face to face educational programs to communicate findings to stakeholders and the general public.

In the coming year we will work with the Southern Region Center for Food Safety Education, Outreach, Training and Technical Assistance Team to remain current on FSMA updates, to participate in the train the trainer program directed by the Produce Safety Alliance, and train our Exempt farmers to design farm food safety manuals. Our goal is 100% FSMA compliance. Organic and Sustainable Horticulture. Publish findings from the SARE study, present findings at ASHS and ASA, and apply for additional grant funds.

Impacts
What was accomplished under these goals? Production and Distribution. Since 2012, I have provided leadership for the Farm to School team. Beginning in 2015, the Farm to School team transitioned from funding provided by the Florida Department of Agriculture to Florida SNAP-Ed. The University of Florida is the authorized entity of Florida SNAP-Ed, termed the Family Nutrition Program (FNP). The accomplishments of the farm to school, farm to community team (F2SC) were made possible by nurturing strategic collaborations with a great diversity of community partners, including farmers, state and federal agencies, nonprofit organizations and private enterprises using a variety of communication methods including: face-to-face, telephone, email, formal training programs, field days, and tours. The F2SC had direct contact with 858 stakeholders, of which 6% were farmers, and provided service and capacity building to the community. Team members were invited or volunteered to serve on 12 standing food policy, wellness, and food systems committees and worked with 102 individual collaborators. The F2SC team supported local food procurement at all levels, from small-scale gardens to large-scale school food purchasing.Over 100 gardens were installed and maintained with 4,209 beneficiaries enjoying 80,811 active hours in the gardens.School gardens were designed with 85% having 4 of the 5 vegetable sub groups from the new meal pattern and produce was enjoyed as taste tests, in cafeteria lunches, and taken home to be eating with the family.Community gardens around the state covered around ½ acre and had the potential to produce enough food for 65 adults estimated to have a $33,106 retail value during the growing season. 881 or 21.0% of the schools in Florida purchased food from Florida farmers (a total of 409,744 pounds) as a result of direct actions made by the F2SC team.As a testament to the impact F2SC is creating in farm to school procurement the Director of Sarasota Food Nutrition Services said "We would not have been successful without Zach (F2SC South Central Region program coordinator)." Food Safety. Eight Food Safety "Build your own Farm Food Safety Manual" workshops were conducted in 2015 to 133 attendees. A summary of the on-line post workshop questionnaire designed by Dr. Galindo, administered through Qualitrics, and analyzed statistically with ANOVA at alpha = 0.05 relative to the pretest, found the following results: Knowledge gain was 88%, averaged over all participants 72% were very likely to implement a plan, 25% indicated they were likely to implement 100% indicated the workshops met their expectations, 100% would recommend the workshop to others 61% of attendees rated the workshop in the top 20% of all workshops they have attended 93% indicated they were very satisfied and 7% indicated they were satisfied with the overall quality of the workshop 82% were very satisfied with the expertise of the instructors, 17% were satisfied Fifty percent (50%) of attendees indicated they were very likely to have some type of third party audit There was a wide range of types of customers listed, top three were selling directly to consumers (48%), restaurants (24%) and to retailers or wholesale markets (18%). Most attendees had less than 10 years of farming experience and most were farming less than 10 acres. In addition, I will be a co-PI on a USDA-NIFA/FDA grant: Southern Region Center for Food Safety Education, Outreach, Training and Technical Assistance. Primarily, the grant provides for curriculum enhancement to the national food safety curriculum managed by Cornell's Produce Safety Alliance, and supports food safety training for trainers. Organic and Sustainable Horticulture.This year we completed the second year of a two year field trial funded by SR-SARE to examine the influence of plant-based mulches on pepper.
