Interpretive Summary:

Technical Abstract: Increased reliance on supplemental irrigation has begun to deplete the alluvial aquifer in Mississippi. To alleviate nonproductive over-use of groundwater resources, we have developed a web-based irrigation scheduling tool. The Mississippi Irrigation Scheduling Tool (MIST) uses a water balance approach, calculating evapotranspiration from weather data using standard ET equations. User input is minimized by relying on national databases of soils and weather information. MIST is currently being tested in various production management scenarios for corn, soybeans and cotton, and for different alluvial soils common to the Mississippi Delta. The web interface allows users to access the information remotely. Google Maps provides a framework to display and select the features (maps, fields, and wells) via the internet, minimizing computation resources needed by users. Following completion of testing and validation, the research team is planning a tentative general release for the 2012 growing season.
