Manure (and Other Organic Materials) on Soybeans FAQ

Q. Are manure applications allowed on soybeans? (Posted August 2015)

A. Yes, use crop code 9, soybeans with P or K-based manure application. As long as FIV-P is less than 150, manure can be applied to supply the P-removal of the crop up to a cap of 50 pounds of PAN per acre.

Choose reg P rem at the bottom of the scenario page in NuMan Pro.

Bottom line - the manure rate is capped at the P-removal rate or 50 pounds of PAN per acre, whatever comes first.
