Impacts of Organic Fertilizer on Nitrogen Dynamics, and Nitrous Oxide and Methane Emissions in Corn.

The emission of green house gas (GHG) from manure application is an increasing concern because of its impact on air quality and on human and environmental health.  Although, the land application of manure can improve soil quality and crop production, it may increase emissions of GHGs.  Several studies have documented GHGs emissions from cattle farms.  However, data on gaseous emissions in relation to manure management in corn is scanty. This study evaluated effect of manure, compost, and cover crop on nitrogen dynamics, N2O and CH4 emission. This study indicated that nitrogen (N) loss in the form of nitrous oxide (N₂O) emissions from cow manure application in corn can be up to 156 kg ha^-1 yr^-1.
