These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This data set represents the estimated percentage of the 1-km grid cell that is covered by or subject to the agricultural conservation practice (CP330), Contour Farming (CF) on agricultural land by county. Contour Farming is described as "tillage, planting, and other farming operations performed on or near the contour of the field slope." (U.S. Department of Agriculture, 1995) This data set was created with geographic information...

This data set represents the estimated percentage of the 1-km grid cell that is covered by or subject to the agricultural conservation practice (CP606), Subsurface Drains (SD) on agricultural land by county. Subsurface Drains are described as "a conduit, such as corrugated plastic tubing, tile, or pipe, installed beneath the ground surface to collect and/or convey drainage." (U.S. Department of Agriculture, 1995) This data set was...

This record describes a series of rasters containing mean monthly total nitrogen, ammonium, and nitrate atmospheric wet deposition. These data were estimated by multiplying together interpolated gridded surfaces of concentration (fNTN) and precipitation (PRISM). The concentration surfaces were produced through inverse distance weighting both the mean monthly ammonium, nitrate, and total nitrogen concentration estimates measured at the NADP monitoring sites (National Atmospheric Deposition Program 2019). The concentration surfaces were interpolated to a 4-km grid (same grid as precipitation) using the IDW R package. Wet deposition was then estimated as the product of the concentration surfaces and monthly precipitation...

This data set represents the estimated percentage of the 1-km grid cell that is covered by or subject to the agricultural conservation practice (CP430), Irrigation Water Conveyance by Pipelines (IWCP) on agricultural land by county. Irrigation Water Conveyance by Pipelines is described as "a pipeline and appurtenances installed in an irrigation system."
