Modeling Illuminates Cover Crop Impact on Cash Crops

Scientists at the University of Illinois teamed computer modeling with field data to shed light on how cover crops can impact cash crop yield. The study revealed that proper management is key to maximizing benefits of cover crops and minimizing negative impact on cash crops. Choosing the right cover crop and planting and terminating it at the right time are the keys to success with cover crops. Soil factors such as the levels of oxygen, nitrogen, and water in the soil also play an important role in choosing the best cover crop for a particular site and cash crop.
