Abstract:

CornSoyWater: web/mobile App for Irrigation decision making of Corn and Soybean fields

CornSoyWater (http://cornsoywater.unl.edu) is a real-time web and mobile app that helps irrigators track soil available water and crop water stress, and determine when to irrigate corn and soybean fields. CornSoyWater aims to optimize irrigation decision making by predicting crop development, water uptake and water balance and possible crop water stress using the Hybrid-Maize model for corn and SoySim for soybean. CornSoyWater reports to users the following using graphic plots: 1) amount of available water in soil rooting depth, 2), crop development stage and corresponding threshold of water depletion to trigger irrigation, 3) quantitative evaluation of crop water stress based on combined transpiration deficit and soil water depletion, 4) recommendation for irrigation if crop water stress is predicted to occur, 5) past rainfall events and irrigation records. CornSoyWater mobile app can be downloaded from Apple Store and Google Play. CornSoyWater program currently covers the High Plains region of the USA but can be adopted for any regions where daily real-time weather data is available. The program can also be adopted for other crops besides corn and soybean.
