Session Description: Nutrient recommendations are being called upon to meet many objectives, such as increased efficiency, increased production, and lower environmental losses; however, farmers, who are the ones making the final fertilization decisions, are most concerned about profitability. This symposium examines various methodologies for incorporating economic variables into fertilizer recommendations. Approaches range from short-term considerations for one nutrient to long-term optimizations that consider multiple factors simultaneously. Presentations will span this range of complexity to assess how far science has come and where it must go in the future to improve the economic decision-making of farmers.
