RESEARCH TOPIC

I am researching a method to convert dairy manure into a better fertilizer to reduce greenhouse gas emissions, minimize environmental impacts, and enhance the economic feasibility of dairy operations. The chemical and physical variability of animal wastes makes it difficult to predict the carbon and nitrogen mineralization rates and nutrient value. Storage and agricultural applications of manure often results in high nutrient runoff and volatilization of greenhouse gases including nitrous oxide, methane, and carbon dioxide. I am testing and optimizing a process that has been developed to physically and chemically alter animal wastes to stabilize and standardize their C and N mineralization properties. The process uses hydrodynamic cavitation and chemical reactions using nitrogenous, iron, and oxidizing compounds to homogenize and create a predictable N source for agricultural crops. Gas analysis performed using advanced Cavity Ring Down Spectroscopy (CRDS) with stable isotope analysis is used to understand the sources and pathways of GHG emissions to optimize the processed waste and its behavior in soil.
