This report includes preliminary data for the second of a three-year study. Since this year was a record drought year, results could vary from a normal rainfall year. Finalized data and observations will be released in future as peer-reviewed studies, reports, and extension articles. For more information, please visit the RDFA project page.

This report presents the data from the third year of a three-year study. In this relatively wet season, fall-planted cover crops, particularly winter peas and the fall mix, produced substantial biomass and provided season-long ground cover. Spring-planted cover crops had insufficient time to grow before termination was necessary and did not produce substantial biomass. More details about the RDFA project can be found at the project's main page (link provided on .pdf).
