Abstract

Northeast Mississippi producers have been using on-farm water storage (OFWS) systems to capture and store surface water to be reused later for center pivot irrigation. Northeast Mississippi producers have limited water availability when irrigating and need to conserve water, and one possible solution is variable-rate irrigation (VRI). In this study, the effectiveness of VRI was studied on a production field, and conventional irrigation (CI) was implemented on three other production fields with the goal of determining the potential for VRI based on factors like elevation and soil type. Yield and soil water tension data were evaluated to determine the potential effectiveness of VRI. A geospatial inventory was created to track changes in irrigation infrastructure in northeast Mississippi over time, and the inventory was also compared to survey and water permit data. Quantifying irrigation infrastructure shows the need for more technical and financial assistance for producers in northeast Mississippi.
