Layer: Corn/Soybeans - Wet (High Tile) (ID: 4)

Name: Corn/Soybeans - Wet (High Tile)

Display Field:

Type: Raster Layer

Geometry Type: null

Description: Corn/Soybean cropland on wet soils in area with high proportion of reported tile drainage within the Mississippi River Basin, minimum size - 1 acre. Minimum field size of 5 acres used as input. In this case a "wet soil" is a Gridded SSURGO mapunit where "pwsl1pomu" (Potential Wetland Landscape) is at least 60 or at least 50 and "drclassdcd" (Drainage Class - Dominant Condition) is poorly or very poorly drained. These mapunits represent those with the highest wetland potential based on these conservative criteria. Drainage class criteria was included to account for mapunit inconsistencies across county/state lines. Areas with high proportion of tile drainage are those counties that contain at least 40,000 tile drained acres as identified in either NASS, NPWRC, or WRI datasets. Tile drainage data sources: 2012 USDA NASS Census of Agriculture; World Resources Institute. 2008. Assessing Farm Drainage <http://www.wri.org/publication/assessing-us-farm-drainage>; USGS Northern Prairie Wildlife Research Center. 2014. Assessment of agricultural subsoil pattern tile drainage on wetland hydrology and ecosystem services in the Prairie Pothole Region <https://www.sciencebase.gov/catalog/item/52fb9ea6e4b00c6b800b98ff>.
