New Chart Helps Growers Choose The Best Cover Crop
June 9, 2015 USDA scientists have developed a Cover Crop Chart that helps growers determine the best cover crop to meet their management and production needs.
Soil scientist Mark Liebig and his colleagues with the Agricultural Research Service’s (ARS) Northern Great Plains Research Laboratory (NGPRL) in Mandan, ND, created the Cover Crop Chart, which can be downloaded for free at www.mandan.ars.usda.gov.
Cover crops are used to help reduce soil erosion, increase organic matter, improve early weed control and provide forage for animals. By providing these services, cover crops can create more resilient and efficient production systems.
The interactive chart, which was recently updated from its first release in 2010, gives growers a broad spectrum of potential options that could benefit their operations. The chart includes information on crop species that may be planted individually or in mixtures and gives specifics on growth cycle, water use, plant architecture, forage quality, pollination and more. Crops are categorized by similar attributes — cool season or warm season, grasses or broadleaf and legumes or non-legumes.
The updated chart now includes 58 cover crop species.
