Research Statement

I like to study soil and its content, specifically nutrient (phosphorus and nitrogen) cycling. I am interested in the practical application of scientific findings to improve sustainability and productivity. In the Nutrient Management Spear Program, I am involved with the Phosphorus Index (PI) and Nutrient Mass Balance (NMB) projects. With the PI project, we aim to keep phosphorus on the fields and out of the surface water. The PI is designed to identify fields that have a high risk for phosphorus loss, and to encourage best management practices in manure allocation and spreading. In the NMB project, we calculate whole-farm nutrient balances, which can be used as a tool to identify areas of opportunity for improving farm efficiency and sustainability.
