4R Nutrient Stewardship
4R Nutrient Stewardship — Right Source, Right Rate, Right Time, and Right Place — provides a science-based approach to fertilizer management that optimizes crop production and on-farm economics while protecting the environment.
What is 4R Nutrient Stewardship?
4R Nutrient Stewardship is a proven framework that optimizes crop production and on-farm economics while protecting the environment. By using the right source of nutrients at the right rate, at the right time, and in the right place, growers can maximize crop yields, improve net farm profits, and minimize environmental impact.
