Even with excellent nutrient management, nitrate losses from corn and soybean fields can occur because these cash crops only grow and take up nitrate and water for five months of the year. Cover crops like winter rye can be an effective strategy for reducing nitrate losses to groundwater or tile drainage because they can take up water and nitrate during the period between harvest and planting of the next year’s crop.
Dr. Tom Kaspar, Plant Physiologist at the USDA-ARS National Laboratory for Agriculture and the Environment, will share his lessons learned over his storied career researching the use of cover crops and no-till to improve water quality and soil health in corn and soybean production systems.
