Calculating plant-available nitrogen and residual nitrogen fertilizer value in manure (2007)

Manure typically is used as a fertilizer for crop production. This guide details the calculations needed to determine the fertilizer nitrogen value of manure, termed 'plant-available nitrogen' (PAN). The guide also details 'residual nitrogen fertilizer value' (RNFV), which is a method used to determine the amount of nitrogen released by manure in the year after application. There are also examples of incorporating an estimate of plant-available nitrogen and residual nitrogen value into a manure application recommendation for a crop.New 12/07/W
