This mobile app generates a recommendation for the most economical N rate for a corn field. It is based on more than 40 years of Ontario research and takes into account soil type, rotation, and the cost scenario (i.e. anticipated cost of N and price of corn). The app allows you to save the recommendations for each field and to generate an email report.
