Charles Wortmann and, Charles Shapiro (June, 2012)

Summary

Manure has value for crop production when it provides nutrients or soil amendments needed form optimum crop yields. A worksheet is provided for calculating the fertilizer value of a manure source for a specific field. It includes the value of needed nutrients for a four-year period and offers the option of including the value of manure nutrients used after that. The value of other benefits of using manure, such as an expected yield increase, can be estimated.
