Study Reveals Best Cover Crop Practices for Optimizing Yields

A study published by Penn State University researchers in Agronomy Journal focused on identifying the best practices for cover crops to optimize cash-crop yields. Specifically, the study looked at the impact of cereal rye seeding rate, termination time, and nitrogen rate on both the soil and a soybean crop. The researchers found that rye seeding rate had no impact on rye biomass or soil moisture. They also discovered that planting green combined with the lowest rye seeding rate and lowest nitrogen rate kept soybeans yields stable, which they say could help producers save money on both cover crop seed and nitrogen supplements.
