Non Technical Summary
This project is designed to expand on known advantages of soil water conservation in irrigated agricultural production on highly permeable soils. Sandy soil types require this new subsurface water retention technology (SWRT) for best water conservation for irrigated agriculture. We believe this research and applied field testing will result less water use by irrigation agricultural production across the USA.

Goals / Objectives
Our major goal of this project are to combine recent advancements in computer-aided engineering evolutionary multi-objective optimization (EMO) methodologies with SWRT water conservation practices to identify the most water use efficient irrigation systems for maximum plant production on highly permeable soils. These computational optimal solutions that identify the efficiency of energy and water use for sustainable production systems will be applied across highly permeable soil types for different climate regions.
Project Methods
Our methods involve an integration of three computational approaches to best design the most water efficient SWRT membrane design in the rhizosphere. We will use HYDRUS for modeling the subsurface volumetric water content within plant root zones lined with SWRT membranes. We will combine EMO for optimizing membrane dimensions and their arrangement along with irrigation scheduling, Then use the USDA root zone water quality monitor (RZWQM) for modeling crop growth that enables us to approach a new level of water use efficient and sustainable irrigation system that is most economical and energy efficient. Solutions obtained by the EMO based approach will be validated by laboratory experiments and applied to multiple farmlands improved by SWRT membranes across USA. For a particular farmland, first the soil properties and precipitation information will be collected and represented as fuzzy numbers and will be handled using fuzzy logic system. Based on the crop being grown for the planned time period, the desired depth-wise volumetric water content and nutrient content will be acquired from the published literature and practices, and also supplemented by the HYDRUS modeler.

Target Audience:Agricultural industries and farming communities on sand soils Changes/Problems:Digital controls and recordings of SWRT membrane presention and soil filling by all four chisels of the improved SWRT membrane installation chisel which installs four fail-safe membranes at exact spatial horizontal and with depth positions for best approach for maximizing and maintaining optimal soil water, nutrients and oxygen in plant root zones growing on sand soils. SWRT improvement of crop production efficiency offers an exciting opportunity to transform highly permeable soils into maximum efficiency of water, labor, energy. Current production levels of 338 bushels of maize grain and fodder production levels of 18.9 tons per acre annually by prescription irrigation of corn growing on SWRT improved sands, currently containing less than 1% soil organic matter has tremendous potential across the entire spectrum of US agriculture. Calculations of at least 9 tons of C, based upon Iowa values of 50% C in each ton of maize fodder, at least 9 tons of carbon per acre (21.2 MT/h) incorporated annually into at least 300 million acres of sand soils, can sequester 2.7 billion tons of C annually. This highly successful agricultural production enhacement and environmental protection SWRT transformed agricultural technology offers extraordinary opportunities for US agricultural exports, farm gate profits, climate change and groundwater protection. This patented, fully tested, and NRCS/CIG field-proven agricultural technology requires Farm Bill subsidies for a few decades, similar to the historic government subsidies for farmer installation of drainage tile systems since the 1960. What opportunities for training and professional development has the project provided?This was the year to test how many new irrigation and fertigation management practices are needed to maximize SWRTmembrane enhancements of parental isolines of the hybrid corn variety, which produced a record high 338 bu/a of grain. Greater shoot to root ratios (S:R), lower root death and turnover, plant tasselling and ear silking synchrony along with other phenological sequencings have been compared to determine best soil water and nutrient retention required to maximize ear filling by larger corn plants. Similar soil monitoring of tomatoes, water melon and spicy peppers growing on SWRT membranes, combined with multiple nutrient retention, absorption and leaching are providing valuable baseline information for training farmers and their agronomic advisors how to precisely manage soil and nutrient levels which produce highest crop yields. These data both provide background information for best production practices on SWRT improved sands and this information is foundational to the next generation of best management practices for highest levels of conservation when addressing the Water-Energy-Food Nexus. This research is designed to identify the most efficient irrigation/fertigation with less energy. Conventional irrigation and soil nutrients were used on the vegetable crops in SW USA to identify specific improvements necessary to maximize production with less water, nutrients and energy. These conventional farmer management practices emphasized the need to train irrigation applicators with the best prescription practices identified by past SWRT research. How have the results been disseminated to communities of interest?SWRT membrane field research provided training for colleagues at MSU, visiting professionals, manufacturing and small business professionals, bankers, crop insurance personnel, undergraduate students and graduate students. Prescription level irrigation scheduling and nutrient balances are needed for highest production of crops growing on SWRT membranes. Best IWUE coupled with low energy and nutrient requirements are being taught to industry service providers. A new SWRT Solutions website has been contracted to highlight all components of SWRT conversions of highly permeable soils into sustainable agricultural production. Three posters and four oral reports have been presented at national and international conferences and symposia. Multiple manuscripts are at multiple stages of publication. What do you plan to do during the next reporting period to accomplish the goals?SWRT Solutions, LLC has a new website: http://swrtsolutions.weebly.com to attract more interested farmers and agricultural irrigation managers with the new prescription irrigation scheduling that improves IWUE while protecting groundwater contamination by deep leaching. Our goal is to complete and submit multiple manuscripts to scientific journals, as book chapters, and extension bulletins on an improved website for SWRT Solutions improvement of sand soils across multiple agroecosystems.

Impacts
What was accomplished under these goals? Combinations of HYDRUS with DSSAT have been incorporated into the EMO. This new EMO ouput paralleled actual data production of maize on the SWRT field trials which were irrigated to soil volumetric water contents (VWC) in the 10 to 30 cm depths. Constant human involvement with Lindsey's FieldNet provided prescription levels between 15% and 17% VWC at 15 and 30cm in plant root zones. This modeling is the beginning of identifying greater opportunities for expanding agricultural production on sands by the SWRT enhancements for greater irrigation water use efficiency (IWUE) while reducing groundwater pollution. Only the surface water scheduling parameter was used as a variable and one of four different membrane shapes and their placement plans are kept fixed in a single run. The combined EMO models with the HYDRUS-2D identified most efficient irrigation energy required for best IWUE for aspect ratios of SWRT membrane ranging from 2:1, 3:1 and 5:1 to verify the 2:1 aspect ratio maintained nearly three times more water for longer periods of time.

Target Audience: Target audiences for this project are mainly farmers. Industry for manufacturing membrane installation devices and small business membrane installers. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided? SWRT membrane field research provides trainingfor colleagues at MSU,visiting professionals, manufacturing and small business professionals,bankers, crop insurance personnel,undergraduate students and graduate students. All gain field experience with the installation process, crop and soil best management systems, irrigation systems, crop production, analyses of data, research reporting, website development and manuscripts for publication. How have the results been disseminated to communities of interest? Plant production increases by the irrigated and non-irrigatedSWRT membrane improvements have attracted literally dozens of farmers, small industries, John Deere, small businessinvestors, Pioneer and DeKalb seed corn companies and irrigation companies. What do you plan to do during the next reporting period to accomplish the goals? As with all new technologies, there will be a need for additional training of farm managers to accurately manage SWRT systems coupled with prescription-based best management practices for SWRT improved sand soils for maximum pro­duction. As more new paradigm-changing technologies surface, additional educational cooperation between owners and opera­tors of commercial and large farms, local equipment dealers, and soil water engi­neering firms becomes more essential. As employment increases, local communi­ties surrounded by sand soils will prosper. Newly franchised businesses are emerging among farm equipment sales and service companies. As SWRT field research con­tinues, new precision management practices will become more profitable, resulting in greater farmer interest in SWRT improvements of their sandy soils. Soil water retention technology water-saving soil treatments must be adopted to eliminate the high risk and uncertainty associated with plant water deficits. This new SWRT has the potential to amelio­rate sandy soil regions that provide multiple ecosystem services to rural communities experiencing job losses and depressed econ­omies. Since most rural farming operations insure planted crops to financially offset unpredictable weather and climate conditions that reduce plant productivity, SWRT-enhanced plant production offers additional crop protec­tion, reducing insurance payments for crop losses enabling industry-wide reductions in crop insurance premiums, a win-win savings for both producers and insurance companies. Soil water retention technol­ogy transformations of highly permeable soils into sustainable agricultural production enables farmers to achieve the necessary 70% expansion of global food production by 2050 with less water. SWRT will con­tinue to secure water for food that meets the nutritional needs of billions even as climates change across continents. Successful contacts with industry, entrepreneural business, banking and crop insurance organizations are leading to MEDC road map development, state conservationist is considering including SWRT membranes into the MI CIG, next year. Irrigation companies are expanding their interest and support of the SWRT membrane water conservation approach for expanding successful agriculture on farmlands located in sandy regions of Michigan.

Impacts
What was accomplished under these goals? Major goals of this project are to expand farmer, industry and small business interests in the new Subsurface Water Retention Technology (SWRT). This is being accomplished by placing new SWRT membranes in sandy soils on active agriculture farm lands across the USA, with an emphasis on MI, MO and AZ.Currentexpansion of the SWRTmembranes from two university experimental station projects includes three on farm sites in TX. To license an established agricultural industry tofurther develop and manufacture new commercial SWRT membrane installation device (MID) implement that expands the previously developed MID prototype implement. Significant progress has been achieved by the RWF BRON manufacturing companyduring these past few months. A new fail-safe commercial implement simultaneously installstwo or moremembranes 18 inches wide from rolls of LDPE, transports these films belowground and positions them in specific 2:1 aspect ratios before filling them with soil overburden passing over the membrane installation device (MID) chisel without major disturbance of the soil profile. Optimal membrane depths are primarily determined by soil texture controlling capillary rise of water, ranging from 17 cm to 38 cm for coarse to fine sands. Depths of membranes are adjusted based upon capillary rise, tillage and rooting depths of plants. We anticipate new membrane installation devices for installing SWRT water conservation will be on the public market by the end of 2014 by RWF BRON. We are beginning the training of certified and licensed water saving membrane installers.Discussions for subsidizing the installation of SWRT water and nutrient saving membranes on farms participating in the Environmental Quality Incentives Program (EQIP) and CIG grant agreement provisions by state NRCS are underway in Michigan and should be established for national funding in drought prone areas with limited water resources in a manner similar to the promotion of soil drainage systems among poorly drained soils supported by the original Soil Conservation Service, now the NRCS, in 1960 through 1990. To develop algorithms for HYDRUS-2D that benefit the accuracy of selecting best aspect ratios of SWRT membranes, installation depths of SWRT membranes in a range of coarse textured soils. HYDRUS-2D algorithms have been developed to accurately predict SWRT membrane retention rates of water, nitrogen, potassium and phosphorus. This model projects the most ideal membrane depth and configuration for maintaining optimal air to water ratios and nutrient flux rates in multiple soil textures. Using the soil water retention graph we can model hydropedological optimizations of plant-available water at multiple distances above SWRT membranes. For example, calculations of soil water diffusivity, 0.85 to 1.75 x10-3 cm h-1, to roots located at multiple distances above SWRT membranes exceed transpiration rates needed by maize planted at very high populations. Consequently, we now have a highly useful model for projecting much broader applications of SWRT water and nutrient saving membranes, well beyond sand soils. This phenomenon is now being tested as we expand demonstrations on sandy loam soils with the goal of increasing yields along hilltops of eroded soils located in the agricultural heartlands of America. We estimate these findings expand the positive contributions for SWRT to sustainably improve agricultural production on an additional 200 million acres of agricultural soils across the USA. This new soil water retention technology (SWRT) rearranges the hydropedology within plant root zone by improving the quantity and homogeneity of soil water above the U-shaped impermeable SWRT membranes. Collaborative soil physics and engineering research has developed, field tested a highly sustainable SWRT membrane that doubles soil water holding capacities increasing plant production by 44% among vegetables to 238% of grain crops beyond irrigated controls. These same SWRT impermeable membranes capture nutrients and agricultural chemicals reducing deep leaching losses of both nitrogen and potassium into groundwater. Additional ecosystem services by SWRT membranes include increased soil carbon sequestration, formation of new stable soil aggregates, increased water use efficiency, increased shoot to root ratios, and reduced root turnover within the root zone above membranes installed in fields of surface drip tape irrigated horticultural beds and row crop. Vegetable crops of cucumber and squash, grown on beds of homogeneous Spinks sand underlined with SWRT membranes, during the past 4 months, produced 28% more commercial cucumber products and 44% more commercial squash products than irrigated controls without SWRT membranes. Although major differences are observed among soil water contents, nutrient concentrations, plant height and plant nutrient deficiency symptoms of corn and soybeans growing on irrigated and non-irrigated SWRT membrane and control plots without membrane water and nutrient retainers, harvest has been delayed by the moisture and warm weather. SWRT U-shaped water-saving mem­branes, having 2:1 width to depth aspect ratios, retain more soil water content for longer time periods in arid regions receiving site-specific irrigation frequencies and rates that establish opti­mal soil VWC between 15% and 17%. Combinations of greater corn grain production coupled with higher glucose and other free sugar levels in the grain of corn grown on irrigated sand equipped with SWRT improved water retention, continuously supplies plant-available water, produced 317% more ethanol than non-irrigated corn growing on controls without SWRT membranes.
