Introduction

My research and extension education programs are focused on soil nutrient management and plant mineral nutrition. My current work concentrates primarily on environmental issues related to nutrient management of corn cropping systems. I seek to identify and implement nitrogen management practices that are sustainable both in terms of minimizing environmental impacts, specifically water quality, and improving crop yields.
