Soil Calculators

Post-Harvest N Management Evaluation
A post-harvest assessment of grain yield, protein and test weight by field or zone within the field can help you evaluate what went wrong (or right) during the crop year and inform your plans for next year. Post-harvest evaluations can also give you important insights into field conditions such as residual soil nitrogen that may impact the crop next year.


Nitrogen & Post-Harvest Calculators
These dynamic tools help calculate nitrogen supply needed to meet grain yield and quality goals and the efficiency of nitrogen based on post-harvest data. These tools are based on the Extension bulletin Dryland Winter Wheat: Eastern Washington Nutrient Management Guide.
