About this app

This application is designed for winter wheat and winter canola producers outside of Oklahoma to use to calculate the number of growing days since the crop was planted (GDD>0). This calculation can be used for Sensor Based Nitrogen Management strategies that utilize the GreenSeeker Sensor and N-Rich Strip. Also included in this application is a cumulative Growing Degree Day (GDD) calculator. Crops included in this calculator are: Wheat, Grass hay, Alfalfa, Corn, Cotton, Peanut, Sorghum, and Soybean. The application uses user zip code to identify where temperature data is collected from.
