Coly soils lack a mollic epipedon and are on upland side slopes. Hobbs soils are stratified above a depth of 10 inches and formed in alluvium on flood plains. Holdrege, Lowry and Nuckolls soils are on similar landscape positions. Hord soils are on stream terraces. Runoff is low to very high depending on slope.
Permeability is moderate.
Most of the acreage of these soils is in native grass. Big bluestem, little bluestem, sideoats grama, blue grama, and western wheatgrass are the dominant species. Cultivated areas are cropped mainly to corn, winter wheat, sorghum, and alfalfa. The soil is extensive. Harlan County, Nebraska, 1970.
