While nitrogen (N) is an essential nutrient for corn, its leaching to ground water is an serious environmental issue and a hazard to public health. N leaching is closely linked to weather factors, especially rainfall. Prediction of N leaching in cropping systems is critical to improvement of crop management and reduction of N leaching. The objective of this project is to develop a web app that predicts in real-time mode N leaching across Nebraska using real-time weather data.

We are in the processing of developing the web app and expect a prototype to be running in 2017 cropping season. Field research will be carried out to test and validate the app predictions. Once completed, the app can help farmers understand better the fate of soil N, improve fertilizer management, and reduce N leaching losses.
