Expertise

Dr. Nelson’s interest in soil fertility and nutrient management extends to both agricultural production and environmental quality. Those two areas of concern can easily co-exist, he firmly believes. His research also focuses on measuring the environmental impacts of other nutrients, such as nitrogen, at the watershed scale.
