How does MMP estimate how much nitrogen will be lost from manure applied to a field?
MMP uses an N loss algorithm developed by Dr. Jay Johnson of Ohio State University. This algorithm takes into account manure nitrogen content (total N and ammonium N), method of application, time of application, soil type, and long-term weather averages to estimate how much manure N will be available to the crop. • How does MMP determine what crop the manure is fertilizing? MMP assumes that manure applied beginning in July is for the following year’s crop. If you plan to apply manure during July and August that is intended for the currently growing crop (for example, through irrigation), you can enter this application in June on the Manure Apps panel to trick MMP into including it in the manure total for the current crop. Be sure to document in the application’s Notes column that the manure will actually be applied later in the summer. • How can I sort one of the data entry grids? You can sort the Fields, Soil Tests, Storage, Animals, Analysis and Equipment grids by any column. Simply
