Crop Removal Values as used in NMAN2 (February, 2008)

This chart summarizes the values currently used in NMAN to calculate crop removal balances for N and P. The values are expressed as the kg of N, P₂O₅ or K₂O per tonne of material, as harvested, except for forages which are expressed per tonne of dry matter. Values for grain with straw are based on the tonnage of grain harvested. Blanks indicate missing values.
