Research Interests

My research focus is identifying management practices that benefit both the farmer and the environment. Historically, I have worked towards improving nitrogen (N) management in cropping systems. Using fertilizer N uptake efficiency as a means of identifying these techniques is advantageous for both environment and producer, as more fertilizer N sequestered in the crop means less remaining in the soil as a potential source of pollution. With the use of 15N, I hope to continue work in answering the simple question of where inputs are going and how we might redirect them, which is undoubtedly tied to nutrient cycling in soil systems.
