Outline

Managing nutrients is a key part of an agronomic system. 4R Nutrient Stewardship provides a framework to achieve cropping system goals, such as increased production, increased farmer profitability, enhanced environmental protection and improved sustainability. To achieve those goals, the 4R concept incorporates the Right fertilizer source at the Right rate, at the Right time and in the Right place. This session will cover some recent research on how the movement of nutrients in the cropping system is impacted by 4R practices in corn grain and cotton systems and information on the economic and environmental performance of the practices when farmers use them in the field.
