 I hold a joint position with a primary academic appointment in the Department of Soil, Water, and Climate (80%) and a secondary appointment in the Department of Horticultural Science (20%).  The responsibilities of this position include identifying needs, establishing priorities, and executing a research and extension program in plant nutrition and nutrient management for crop production.  Primary emphasis is on vegetable and fruit crops commercially grown in Minnesota. Efforts in recent years have also focused water quality issues related to fertilizer use and agricultural/horticultural use of municipal and industrial by-products as soil amendments.
