Floridan Aquifer Collaborative Engagement for Sustainability (FACETS) - Field trial data from Live Oak, Florida

Research was conducted at the North Florida Research and Education Center - Suwannee Valley, located near Live Oak, Florida (30°18’22” N, 82°54’00” W). Corn, carrots, peanuts, and rye (cover crop) were grown on Hurricane, Chipley, and Blanton soil complexes that are all over 90% sand. They contain very little organic material or clays and have very low water holding capacity. The experimental design utilized a randomized complete block design with split plot that incorporated two fields with eight blocks (treatment replicates) and fifteen plots per block. The main plots contained four irrigation treatments, and the sub-plots contained three different nitrogen rates. The SMS irrigation treatment contained three additional nitrogen treatments. The plots were 12 m x 6 m separated by 6 m alleys. Each block was separated by a 12 m alley. The north field in the study (System 2) was a corn-cover crop-peanut-cover crop rotation, while the south field (System 1) was a corn-carrot-peanut-cover crop rotation. During each growing season, soil moisture was monitored using capacitance type soil moisture sensors, soil nitrogen was measured through bi-weekly soil samples at four depths, and biomass was collected four times with the final sample being collected just prior to harvest. Biomass included dry weight of separate plant tissues as well as Total Kjeldahl Nitrogen (TKN) and yield.

研究于佛罗里达州利沃奥克附近的北佛罗里达研究教育中心——苏万尼谷地进行。在Hurricane、Chipley和Blanton土壤复合体上种植玉米、胡萝卜、花生和大麦（覆盖作物），这些土壤复合体均含有超过90%的沙质。它们含有极少的有机物质或粘土，且保水能力极低。实验设计采用了随机完全区组设计，并采用裂区设计，包含两个田块和八个区组（处理重复），每个区组包含十五个小区。主区组包含四种灌溉处理，副区组包含三种不同的氮肥施用量。SMS灌溉处理包含三种额外的氮肥处理。小区面积为12米x 6米，由6米宽的走道分隔。每个区组之间由12米宽的走道分隔。研究中的北部田块（系统2）为玉米-覆盖作物-花生-覆盖作物轮作，而南部田块（系统1）为玉米-胡萝卜-花生-覆盖作物轮作。在每一个生长季节，使用电容式土壤水分传感器监测土壤水分，通过每两周采集四个深度的土壤样品来测量土壤氮，并四次收集生物量，最终样本在收获前收集。生物量包括单独植物组织的干重以及总凯氏氮（TKN）和产量。
