Estimating Plant-Available Nitrogen from Manure

This publication discusses management practices that increase crop nitrogen utilization. It also includes an interactive worksheet for calculating available nutrients supplied by manure application. The worksheet can be used to determine the manure application rate needed to supply a target amount of PAN; estimate the dollar value of PAN from manure application; assess the balance between PAN, P, and K supplied by manure; and evaluate management options to increase crop N utilization.
