Accomplishments
1. Winter cover crop management in diverse dairy forage production systems. Winter cover crops are known to prevent soil erosion, recover nutrients, and build soil health, but selecting the best options for cover crop management in diverse dairy forage production systems is complex. Collaborative research conducted by USDA researchers at University Park, Pennsylvania, and colleagues from the Pennsylvania State University in support of the Long-Term Agroecosystem Research (LTAR) network shows that planting winter rye cover crops immediately after corn silage harvest and delaying fall manure application until establishment increased nutrient recovery and improved cover crop yield. Maintaining the winter rye long enough in the spring to harvest silage (double cropping) adds to overall forage production without reducing the yield of the subsequent corn crop. The use of legume cover crops, which can be inter-seeded into summer crops, decreases the need for nitrogen fertilizers and increases the yield of subsequent crops in some years. These management options for dairy forage production systems allow producers to benefit from the soil erosion protection, nutrient recovery, and soil health benefits of winter cover crops.
