Meta-analysis of Enhanced Efficiency Fertilizers in Corn Systems in the Midwest
Enhanced efficiency fertilizers can be an effective means of managing nitrogen to prevent losses to the environment, both to protect natural resources and improve crop yields. However, the range of environmental and management factors that can influence their success can be difficult to put into context. This meta-analysis will help growers, industry, and academics by compiling the most up-to-date information and move the concept of 4R nutrient stewardship and sustainable agriculture forward.
Introduction The 4R approach to nutrient stewardship has helped develop a better context for driving best management practices in production agriculture. As the agricultural community becomes more involved in exploring the three aspects of sustainability, including the economic, social, and environmental triple bottom line, the 4Rs (right source, right rate, right time, and right place) provide a framework for better management of fertilizer applications.
