Abstract: Current nitrogen and phosphorus applications in the Midwest have been connected to increasing water quality problems. In an effort to improve water quality, the Iowa Nutrient Reduction Strategy (INRS), a science and technology-based framework to assess and decrease nutrients to Iowa water and the Gulf of Mexico, was developed in 2013 (INRS 2013). This framework advocates significant voluntary adoption of cover crops, which are planted between harvest and the planting of cash crops. While cover crops were utilized in the past to decrease soil erosion and build up soil organic matter, this technology has been revived recently due to its multi-functionality. Cover crops are very promising as they can reduce both nitrogen and phosphorus losses by around 30 percent (INRS 2013). The INRS proposes several scenarios to meet the N and P reduction goals including two in which row crop land cover crop adoption rates are proposed. Some Eastern states have recognized the importance of this practice such as Indiana, where 7.1 percent of farmland planted cover crops (Rundquist and Carlson 2017).
