This data is from 19 on-farm studies in Minnesota to evaluate the use of cover crops to trap nutrients from fall manure applications and release them during the growing season for the following cash crop. It includes the amount of above-ground biomass that was produced by the cover crop (CC), soil nitrate in the top 24 inches of soil in plots with and without CC, and yields of the following cash crop in plots with and without CC. There is also data on CC and corn nitrogen uptake. This data was published in a peer-reviewed journal article and is now released.
A Microsoft Excel spreadsheet is included with the data. Detailed documentation can be found in the attached document.
This research was funded by a Section 319 grant from the U.S. Environmental Protection Agency through the Minnesota Pollution Control Agency, grant number 103675/PO3000015229, and by funds from the Minnesota Agricultural Experiment Station, University of Minnesota.
