Manure and Soil Health: What is the State of the Science? Can manure be both an economic ‘Win’ and an environmental ‘Win’? What fields provide the best opportunity for Win/Win? What exactly are the environmental and soil health wins associated with manure? Can we test soils so that we better understand the value of manure nutrients and carbon? What are the biological processes in a soil system that benefit from organic fertilizers? These and other questions are the topics a new working group addressing Manure and Soil Health (MaSH) plan to address.
