Dr. Rosen specializes in mineral nutrition of horticultural crops. His research concerns environmental assessment of nitrogen use in agricultural soils as well as nitrogen acquisition by various vegetable and fruit crops. An additional research focus is the beneficial use and recycling of various municipal wastes for horticultural and agronomic purposes.

Dr. Rosen holds a joint appointment in the Department of Soil, Water, and Climate and the Department of Horticultural Science. He has extension responsibilities in soil fertility aspects of horticultural crops. He is also on the graduate faculty in soil science.
