The mission of the Cornell University's Nutrient Management Spear Program is to assess current knowledge, identify research and educational needs, conduct applied, field and laboratory-based research, facilitate technology and knowledge transfer, and aid in the on-farm implementation of beneficial strategies for field crop nutrient management, including timely application of organic and inorganic nutrient sources to improve profitability and competitiveness of New York State farms while protecting the environment. Our vision: Improved profitability and competitiveness of New York dairy, livestock, and cash grain operations while maximizing environmental protection. Our motto: Relevant questions and sound science for agricultural profitability and protection of the environment. For more information about our program and focus areas see our NMSP Flyer and/or sign up for our newsletter The Spear.
