Interest in cover crops by agricultural producers has increased the need for information regarding the suitability of crops for addressing different production and natural resource goals. To help address this need, staff at the USDA-ARS Northern Great Plains Research Laboratory developed a decision aid called the Cover Crop Chart (CCC). Visually analogous to the periodic table, the CCC includes information on 46 crop species within a free downloadable Portable Document Format (PDF) file. The CCC serves as a useful educational resource for agriculturalists learning about cover crops for the first time.
