Irrigation Water Management Recovery on Agricultural Land in the Conterminous United States, 1992: National Resource Inventory Conservation Practice 449.

Dataset Identification:

Resource Abstract:
description: This data set represents the estimated percentage of the 1-km grid cell that is covered by or subject to the agricultural conservation practice (CP449), Irrigation Water Management Recovery (IWM) on agricultural land by county. Irrigation Water Management Recovery is described as "the process of determining and controlling the volume, frequency, and application rate of irrigation water in a planned, efficient manner...to promote [a] desired crop response." (U.S. Department of Agriculture, 1995) This data set was created with geographic information systems (GIS) and database management tools. The acres on which IWM'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.; abstract: This data set represents the estimated percentage of the 1-km grid cell that is covered by or subject to the agricultural conservation practice (CP449), Irrigation Water Management Recovery (IWM) on agricultural land by county.
