Parent material - till from mixed sources. Mean annual precipitation - 12 to 19 inches. Areas with less than about 15 inches have cooler temperatures and lower evaporation. The lower elevation and higher precipitation were added for South Dakota. Runoff is negligible to high depending on slope.
Permeability is moderately slow above the till and slow or moderately slow below.
Vida soils are used mainly for dryland crops and as rangeland. Potential native vegetation is mainly bluebunch wheatgrass, western wheatgrass, needleandthread, little bluestem, and perennial forbs. Vida soils are extensive on the till plains of northern Montana, northwestern North Dakota, and till plains of northeastern South Dakota. Dawson County, Montana, 1971.
