Target Audience:Our research and extension efforts were targeted toward scientists, Extension Agents and Specialists, regulatory officials, consultants, agricultural professionals, and farmers in the Southeast. Changes/Problems:
Nothing Reported
What opportunities for training and professional development has the project provided?In 2018, I had 62 consultations, 10 Field Days, 10 Extension Agents trainings (ISTs) talks and workshops, 4 reviewed Extension publications, and 8 popular press articles, reaching a total of 54,409 people. How have the results been disseminated to communities of interest? Cover crop crimping-rolling coupled with precision planting (sometimes in a single pass) has been implemented for the first time in Santa Rosa County by three influential growers during 2017-18. This is expected to increase cover crop adoption in the county. The technology was first demonstrated using our on-farm trial in coordination with Extension Agents, FDACS, and the Water Management District in the county. The grower who first used this technology in conjunction with a (poorly managed) rye cover crop in 2016-17 reported an average dryland cotton lint yield increase of 100 lbs/ac, which we attributed to improved soil moisture under a terminated cover crop. The improved soil moisture status was quantified using soil moisture sensors obtained by BMP grantsmanship. These grants are now obtained directly by agents after initial help from my program (see Section 18). These growers reported the intention to improve the management of their cover crops to further increase the benefit to dryland cotton production. One of these influential growers is using the technology to direct-plant cotton into a tillage radish cover crop without the use of chemical termination, saving at least three passes at approximately $6/ac per pass and likely improved nematode control. These growers represent 3800 acres in Santa Rosa County. 100% of County and Regional Agents, covering an estimated 434,000 acres, that attended my IST plan to use data management protocols and techniques 'most of the time' or 'almost always.' Agent-developed protocols learned in ISTs are currently in use for agent-directed trials in Santa Rosa, Escambia, and Jackson Counties. Growers who used soil moisture sensors as part of on-farm demonstrations have reported a savings of 20,655,000 gallons of irrigation water in Escambia County over three years. These growers have adopted the technology on all of their irrigated acreage. This highly conservative calculation assumes no adoption by growers who attended our workshops or read our article in Peanut Grower magazine, and is limited only to those growers I have directly worked with. Future program evaluation will assess the continued adoption of this technology. Educational activities promoting the technology include ISTs, Field Days, and On-Farm Demonstrations. Much of the successful grantsmanship by Agents in my area has been focused on adoption and demonstration of this technology (see Section 18). 87% of participants correctly identified P deficiencies in plants after training, up from 38% beforehand. For K deficiencies, the increase was from 38% before to 68% after training. Prior to training, 0% of County and Regional Agents estimated the correct amount of nitrogen credit to crops following peanut. After training, 49% estimated correctly. For growers, these numbers were 52 and 85%, respectively. ? GMOs can increase nutrient-use efficiency. After training, positive perceptions toward GMOs increased from 44% to 67%. A keynote presentation to Master Gardeners at the statewide annual meeting saw positive perceptions increase from 33 to 56%. What do you plan to do during the next reporting period to accomplish the goals?Investigate Brassica carinata as a viable cropping systems option for West Florida. Continue with NUE and WUE improvement strategies. ?
Impacts
What was accomplished under these goals?
Although extension publications throughout the Southeast recommend a nitrogen (N) credit after peanut ranging from 22-67 kg N/ha, there is a lack of scientific peer-reviewed literature to support those recommendations. This research portfolio, collectively published in Agronomy Journal or currently under review, suggested that potential N credits from peanut to subsequent crops depend on: 1) planting date of the subsequent crop, 2) plant residue placement, 3) plant residue load, and 4) latitude/climate. Although potential N credits to subsequent crops were lower than current extension recommendations, we have been able to document the first non-zero N credit from peanut residue in the Southeast. This has important ramifications for the regulatory environment throughout the peanut-growing Southeast, but particularly in Florida where water quality issues due to nutrient loading is a primary concern. Although extension publications throughout the Southeast recommend a nitrogen (N) credit after peanut ranging from 20-60 lbs N/ac, there is a lack of scientific peer-reviewed literature to support those recommendations. My research found that potential N credits from peanut to subsequent crops depend on: 1) planting date of the subsequent crop, 2) plant residue placement and distribution, 3) plant residue load, and 4) climate/latitude. We have documented the first non-zero N credit from peanut residue in the Southeast. This has important ramifications for the regulatory environment throughout the peanut-growing Southeast, but particularly for Florida where water quality issues due to nutrient loading is a concern. State regulators have worked with my program to evaluate the effectiveness of peanut residue to reduce N fertilization of subsequent crops. As more data become available, we will continue to refine those recommendations. FDACS has amended the statewide "How to Comply Fertilizer Manual" based on 2016 Florida Statute 576.011(33) and altered regulatory planning to reduce N fertilization in peanut rotations based on our research results (see Section 13). Florida ranks #5 within the US in the value of mineral production value and produces approximately 25% of global phosphate needs, including 75% of domestic requirements. The statewide fertilizer industry distributes over 1.9 million tons of fertilizer annually in Florida alone. Compliance regulations needed to be updated to reflect current knowledge, protect consumers, and reduce environmental impact. The updated regulations affect 400 registered fertilizer companies within the state of Florida. The soil moisture management extension programming has gained the attention of the FDACS Office of Agricultural Water Policy to initiate policy changes toward cover crop cost-sharing programs. Environmental management and BMP representatives from the office have worked with my extension program to demonstrate the technology on-farm in order to show the effects of cover crops and conservation tillage for improved soil moisture management under dryland conditions that prevail in NW Florida. FDACS is interested in developing cost-share programs for cover crops but requires on-farm demonstrations prior to implementation of a policy change. Cost-sharing of cover crop seed will positively impact the amount of acreage currently planted to cover crops during the fallow season, thereby enhancing dryland soil moisture status and environmental quality.

Progress 10/01/16 to 09/30/17
Outputs
Target Audience:My program provides tools and information related to soil fertility management for Extension Agents, growers, crop consultants, policymakers, and industry professionals and leaders. I also provide training to stakeholders that facilitates the collection, management, and assessment of data related to programmatic activity. Changes/Problems:
Nothing Reported
What opportunities for training and professional development has the project provided?In 2017, I had 61 consultations, 12 Field Days, 3 Extension Agents trainings (ISTs), 11 talks and workshops, 6 reviewed Extension publications, and 10 popular press articles, reaching a total of 42,559 people. How have the results been disseminated to communities of interest? Outcomes: The number of participants or visits involved in my extension activities increased by approximately 150% year-on-year since 2015 (Table 1). 87% of participants correctly identified P deficiencies in plants after training, up from 38% beforehand. For K deficiencies, the increase was from 38% before to 68% after training. Prior to training, 0% of County and Regional Agents estimated the correct amount of nitrogen credit to crops following peanut. After training, 49% estimated correctly. For growers, this number was 52 and 85%, respectively. 100% of County and Regional Agents, covering an estimated 434,000 acres, that attended my IST plan to use data management protocols and techniques most of the time or almost always. Agent-developed protocols learned in ISTs are currently in use for agent-directed trials in Santa Rosa, Escambia, and Jackson Counties. In 2016, positive perceptions of Master Gardeners toward GMOs increased from 44% to 67%. What do you plan to do during the next reporting period to accomplish the goals?Investigate Brassica carinata as a viable cropping systems option for West Florida. Continue with NUE and WUE improvement strategies.

What was accomplished under these goals?
Although extension publications throughout the Southeast recommend a nitrogen (N) credit after peanut between 22-67 kg N/ha, there is a lack of scientific peer-reviewed literature to support those recommendations. Our research, published in Agronomy Journal, found that potential N credits from peanut to subsequent crops depend upon the planting date of the subsequent crop and also on residue placement.In every case, we found that potential N credits to subsequent crops were lower than current extension recommendations. There has been increased interest in sesame as an alternative crop in the Southeast when drought conditions persist in western Texas and Oklahoma.However, fertility requirements and nutrient uptake patterns of sesame in the Southeast were unknown. We found that 74-103 kg N/ha accumulated in biomass and 29-49 kg N/ha was removed in grain. The research found that sesame is an excellent scavenger of residual N and suggests that less mineral N may need to be applied than is needed to meet crop demand.

What opportunities for training and professional development has the project provided?100% of County and Regional Agents, covering an estimated 434,000 acres will use data management protocols and techniques as a result of training provided by my program. Agent-developed protocols learned in ISTs are currently in use for agent-directed fungicide trials in Santa Rosa County. How have the results been disseminated to communities of interest? Outcomes: Based partly on input from my program, FDACS has amended the state-wide "How to Comply Fertilizer Manual" based on 2016 Florida Statute 576.011(33) and altered strategic planning to reduce N fertilization based on peanut rotations. Impacts: Florida ranks #5 within the US in the value of mineral production value and produces approximately 25% of global phosphate needs, including 75% of domestic requirements (dep.state.fl.us). The state-wide fertilizer industry distributes over 1.9 million tons of fertilizer annually in Florida alone. Compliance regulations needed to be updated to reflect current knowledge, protect consumers, and reduce environmental impact.The updated regulations affect 400 registered fertilizer companies within the state of Florida. What do you plan to do during the next reporting period to accomplish the goals?The next reporting period will gather data for the following research priorities: Fertility: ESN release rates for winter crops in Florida. Field studies, Jay, Quincy, & Citra. Potential for precision N application on cotton using NDVI and the Clemson N calculator. Field studies, Jay. Mehlich 3 calibration for P & K in wheat.

Impacts
What was accomplished under these goals?
Growers are already utilizing some improved nutrient management technologies. For example, Walker Farms in Escambia County will implement soil moisture sensors for irrigation optimization on 269 irrigatedacres in 2017 as a result of on-farm work conducted in 2016. We have also documented changes in Master Gardener attitudes on GMOs as a result of workshops, with a decrease in negative perceptions from 28.85% of those attending to 25.45% and an increase in positive perceptions from 44.25% to 67.27%.
