Applied Manure and Nutrient Chemistry for Sustainable Agriculture and Environment

Dr. Zhongqi He is a research chemist at the USDA and works on Commodity Utilization. He is well known and cited in his area of research. Working with colleagues at the ARS New England Plant, Soil, and Water Laboratory in Orono, Maine, Zhongqi He showed that conventional and organic dairy manures from commercial dairy farms differed in concentrations of plant nutrients, including phosphorus, metals and minerals.
