October 24, 2008, St. Paul, Minn. – What’s manure worth? Answering that question can be complicated since many variables will greatly influence manure value in different situations.

A spreadsheet tool, MANURWKST.XLS, written to determine manure value, has recently been redesigned to be more user-friendly for novice users. Bill Lazarus, University of Minnesota Extension agricultural economist; Will Meland, applied economics department, University of Minnesota, and Bob Koehler, former educator with University of Minnesota Extension, have added features that will simplify input and allow for economic comparisons of manure application options.

Many questions regarding manure value that are influenced by commercial fertilizer prices, field selection and crop need, application rate, application method, application cost, manure nutrient content and other management decisions can be answered specific to individual situations by the spreadsheet.

In addition to the manure value calculations, a frequently asked questions (FAQ) section can help to answer common manure value questions and assists the user in using the spreadsheet to deal with their questions.

MANURWKST.XLS, a downloadable spreadsheet (1.05 MB) is available at http://www.apec.umn.edu/faculty/wlazarus/interests_manureworth.html. The software was revised 10/08/08.

The new version was sponsored by and will be distributed to producers and agricultural professionals as part of a Manure Economics Extension program from UM Extension and the Water Resources Center beginning this winter.
