This project aims to understand how biosolids land application will influence soil nutrient cycling, greenhouse gas emissions, and sustainability. The Stillwater Wastewater Treatment Plant is land applying biosolids derived from their treatment system to fertilize crops they later harvest and distribute as cattle feed. We are considering how these biosolids may enhance or inhibit nutrient cycling processes (i.e., denitrification) and greenhouse gas emissions. We also are exploring how life cycle emissions compare between this practice and potential alternatives. The team utilizes a combination of field, lab, and modeling approaches to answer different research questions under this project umbrella.
