Project Background
Enhanced efficiency fertilizers (EEFs) containing urease and nitrification inhibitors are an effective way to prevent ammonia volatilization and reduce nitrous oxide emissions. Through this on-farm trial, North Carolina State University will provide critical information on the efficacy of reducing nitrogen and/or using inhibitors on emissions and corn yield in the low soil carbon, hot and humid conditions of the southeast. This project will use the data to optimize a N2O emission model to support broader interpretations outside the field sites. The on-farm trial will include six field sites each year in the main corn growing regions in North Carolina.
