The Crop Nutrient Tool provides estimates of nutrient removal by crops at various levels. The nutrient percentages utilized in this tool reflect national averages. These estimates are used to calculate nutrient balance sheets, which are employed in the design of animal waste management systems. The Crop Nutrient Tool automates and augments the information that is currently in Chapter 6 of the NRCS Agricultural Waste Management Field Handbook.

The nutrient values contained in the database supporting this tool have been compiled by the Natural Resources Conservation Service from various sources. The values represent estimates of the nutrient content in harvested plant biomass for many different crops.
