This data set represents the estimated percentage of the 1-km grid cell that is covered by or subject to the agricultural conservation practice (CP447), Irrigation System by Tailwater Recovery (ISTR) on agricultural land by county. Irrigation System by Tailwater Recovery is described as "a planned irrigation system in which all facilities utilized for the collection, storage, and transportation of irrigation tailwater for reuse have been installed." (U.S. Department of Agriculture, 1995) Tailwater is the area immediately below a dam where the river water is cooler than normal and rich in nutrients. This data set was created with geographic information systems (GIS) and database management tools. The acres on which ISTR'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.

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).

This data set represents the estimated percentage of the 1-km grid cell that is covered by or subject to the agricultural conservation practice (CPIS04), Stream, Lagoon or Other Waste Waster (not including tailwater recovery) as an Irrigation Source (LWWIS) on agricultural land by county. Stream, Lagoon or Other Waste Waster (not including tailwater recovery) as an Irrigation Source is described as an "impoundment made by excavation or earthfill for biological treatment of animal or other agricultural waste." (U.S. Department of Agriculture, 1995) This data set was created with geographic information systems (GIS) and database management tools. The acres on which LWWIS'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).

This data set represents the estimated percentage of the 1-km grid cell that is covered by or subject to the agricultural conservation practice (CP607), Surface Drainage, Field Ditches (SDFD) on agricultural land by county. Surface Drainage, Field Ditches are described as "a graded ditch for collecting excess water." (U.S. Department of Agriculture, 1995) This data set was created with geographic information systems (GIS) and database management tools. The acres on which SDFD'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).

This data set represents the estimated percentage of the 1-km grid cell that is covered by or subject to the agricultural conservation practice (CP428), Irrigation Water Conveyance by Ditch and Canal (IWCDC) on agricultural land by county. Irrigation Water Conveyance by Ditch and Canal is described as "a fixed lining of impervious material installed in an existing or newly constructed irrigation field ditch or irrigation canal or lateral." (U.S. Department of Agriculture, 1995) This data set was created with geographic information systems (GIS) and database management tools.
