Split Application of Urea Does Not Decrease and May Increase Nitrous Oxide Emissions in Rainfed Corn

Modification of N fertilizer application timing within the growing season has the potential to reduce soil nitrous oxide (N 2 O) emissions but limited data are available to assess its effects. We compared cumulative growing season nitrous oxide emissions (cN 2 O) following urea applied to corn ( Zea... View More
