Quirine Ketterings

Quirine initiated and leads the Cornell Nutrient Management Spear Program Website, the applied research and extension program in nutrient management of field crops of the College of Agricultural and Life Sciences.

Research Focus

Improve understanding of nutrient release and risk for runoff and leaching 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.

Outreach and Extension Focus

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.

Teaching Focus

Prepare Cornell undergraduates for careers in agriculture focusing on increasing farm income while protecting the environment (ANSC4120: 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.
