Pressure Irrigation on Agricultural Land in the Conterminous United States, 1992: National Resource Inventory Conservation Practice IT02
This data set represents the estimated percentage of the 1-km grid cell that is covered by or
subject to the agricultural conservation practice (CPIT02), Pressure Irrigation Source (PI) on
agricultural land by county. Pressure Irrigation Source is described as irrigation "delivered
to the farm and/or field in pump or elevation induced pressure pipelines; and water is distributed
across the field by: 1) Sprinkle irrigation (center pivot, linear move, traveling gun, side roll,
hand move, big gun, or fixed set sprinklers), or, 2) Micro irrigation (drip emitters, continuous
tube bubblers, micro spray or micro sprinklers)." (U.S. Department of Agriculture, 1995) This
data set was created with geographic information systems (GIS) and database management
tools. The acres on which PI's are applied were totaled at the county level in the tabular NRI
database and then apportioned to a raster coverage of agricultural land within the county based
on the Enhanced National Land Cover Dataset (NLCDe) 1-kilometer resolution land cover grids
(Nakagaki, 2003). Federal land is not considered in this analysis because NRI does not record
information on those lands.
