Vulnerability of shallow ground water and drinking-water wells to nitrate in the United States: Model of predicted nitrate concentration in U.S. ground water used for drinking (simulation depth 50 meters) -- Input data set for confined manure (gwava-dw_conf)
This data set represents the average annual nitrogen input from
confined animal manure, 1992 and 1997, in kilograms per hectare,
in the conterminous United States.
		
The data set was used as an input data layer for a national
model to predict nitrate concentration in ground water used for
drinking.
