Current Research:

I established and lead the Cornell Nutrient Management Spear Program (NMSP), the colleges applied research, teaching and extension program for field crop fertilizer and manure management, that aims to improve dairy industry awareness of crop nutrient needs, crop quality, management of organic wastes, environmentally sound nutrient management practices, and overall soil fertility management. In collaboration with Cornell Cooperative Extension field crops educators, private sector crop consultants and nutrient management planners, agricultural industry and regulatory agencies, we conduct extension and applied research that aims to improve our understanding of nutrient cycling and aid in agronomic and environmentally sound nutrient management of dairy and livestock farms. In 2012, we launched the New York On-Farm Research Partnership.

Our specific research focus is to improve understanding of nutrient release and risk for runoff, leaching and/or volatilization and denitrification losses from inorganic and organic amendments as affected by soil type, hydrology, time and rate of application, and the use of specific soil and fertilizer amendments.

Our extension focus is to improve grower and agricultural industry awareness of crop nutrient needs, crop quality, management of organic amendments, environmentally sound nutrient management practices, and overall soil fertility management in New York State, and provide methods and tools to integrate and apply accumulated knowledge about crop nutrient guidelines to optimize crop yield while minimizing risk to the environment.

Our instruction focus is to prepare Cornell undergraduates for careers in agriculture focusing on increasing farm income while protecting the environment (ANSC 4120: whole farm nutrient management) and instill upon Cornell graduate students with a major or minor in soil science the skills, attitude and enthusiasm needed to conduct sound science using interdisciplinary and integrated approaches to address environmental issues related to soil science and nutrient management.
