Nutrient removal by harvest

What a harvest carries off an acre in nitrogen, phosphate, potash, sulfur and magnesium, from IPNI’s coefficients. Pick who is asking, the crop and the yield; add a ZIP code to start from the crop and yield typical of its state.

Optional. The ZIP picks the crop that leads its state and, where USDA publishes one, the state average yield.

bushels per acre

Enter a yield to see what the harvest removes.

Removal coefficients are IPNI’s (January 2018), as hosted by Mosaic Crop Nutrition, and USDA NRCS’s Crop Nutrient Tool. They describe what a harvest carries off the field, not what a soil needs.
