How do I override MMPs estimated manure analysis and production?
Scroll the grid to the right on the Analysis panel and enter a measured manure analysis and production. Be sure to document the source and date of your analysis by entering a lab name or other information in the Source column. • 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
