Planting
N Calculator available for North Dakota producers

Check out the North Dakota Nitrogen Calculator for sunflower. You can find the calculator at https://lamp.ndsu.edu/soils/FourCropsNitrogenCalculatorWebApp/ The calculator uses new nitrogen recommendations, which were 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. The calculator does not immediately support sunflower prices above 30 cents per pound or N prices greater than $1/lb N. However, if you divide each value (sunflower price AND N cost) by 2, and insert these values into the calculator, the proper N recommendation will result. The NDSU Fertilizing Sunflower Circular SF713 with the new recommendations can be found online at: SF713 Fertilizing Sunflower [2016].indd (sunflowernsa.com)
