Nitrogen Losses: A Meta-analysis of 4R Nutrient Management in U.S. Corn-Based Systems
Project Description Read more
The specific aim of this data analysis project was to determine the impact of 4R N management on nitrous oxide (N2O) and nitrate (NO3) environmental losses relative to corn yield. Beginning in May 2014, published data were collected and summarized on 4R fertilizer N management (right rate, source, timing, and placement) in North American corn-based cropping systems.
