DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage: well drained
Saturated hydraulic conductivity: moderately slow
Runoff: slow or medium depending on slope
USE AND VEGETATION: Hemingford soils are mostly cultivated, and some areas are irrigated.
Winter wheat is the principal dryland crop.
Corn, field beans, sugar beets, and alfalfa are the principal irrigated crops.
Where in rangeland, the native vegetation is mid and short grasses.
DISTRIBUTION AND EXTENT: Hemingford soils are of moderate extensive.
They occur in western Nebraska and possibly in adjacent parts of Colorado.
