This project is a continuation of the study to assess soil health, sustainability of the corn-soybean rotation, and risk of phosphorus water quality impairment. The research project will provide science-based information to develop better guidelines to improve water quality and help stakeholders understand how soil P assessments in soil health tools relate to existing methods currently recommended in Iowa for crop production and phosphorus loss risk assessment.
