summary
The main goal of this project is to determine if the University of Minnesota’s current recommendations for manure N and P credits are still applicable. Our data showed that we may need to make adjustments to beef bedded pack and possibly dairy manure, but the last year of the experiment is needed to round out our dataset. In the end, if we are able to provide better recommendations for manure use, then farmers will be able to better maximize their commercial fertilizer purchases, increasing profitability.
