ND Nitrogen Calculator
The calculator uses the new nitrogen recommendations, which have been updated for the first time since the 1970s. There are also new recommendations for phosphorus (P) for sunflower in the Northern Great Plains. The new N and P recommendations are based on general productivity history and not a yield prediction model. N and P recommendations are based on both documented yield responses to each and economic analysis.
