IN THE NEWS: Nutri-Net Project Looks to Quantify the Impact of 4R Nutrient Stewardship Practices
There is a lack of research data linking agronomic and environmental performance across a wide variety of management conditions. This critical research gap is leading to high uncertainty regarding the efficiency of 4R practices for farmers, program managers, and policy- or decision-makers. Industry, universities, and state and federal action agencies have displayed a concerted effort to promote the 4R (Right Source, Right Rate, Right Time, and Right Place) on-farm nutrient management approach to using commercial fertilizer and organic materials (e.g., http://www.nutrientstewardship.com). However, our ability to quantify and track the impacts of 4R management on crop yield, P, K and nitrate loss to water, N loss to the atmosphere, and changes in soil health under a range of practices needs further improvement.
