Changing the fate of nitogen in the agroecosystem

Recent research suggests that the potential for both crop uptake of nitrogen and denitrification increased with controlled drainage/subirrigation, and the loss of nitrogen to drainage waters decreased when compared to conventionally-drained cropping systems. Further research will investigate the cycling of nitrogen and water in agroecosystems.
