Irrigation Land Leveling on Agricultural Land in the Conterminous United States, 1992: National Resource Inventory Conservation Practice 464
This data set represents the estimated percentage of the 1-km grid cell that is covered by or subject to the
agricultural conservation practice (CP464), Irrigation Land Leveling (ILL) on agricultural land by county.
Irrigation Land Leveling is described as "[r]eshaping the surface of land to be irrigated to planned grades.
for the purpose of permitting uniform and efficient application of irrigation water to the leveled land."
(U.S. Department of Agriculture, 1995) This data set was created with geographic information systems
(GIS) and database management tools. The acres on which ILL'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.
