It is formed on uplands from calcareous eolian material. The surface is a loam.The underlying material is a silt loam. The soils have moderate permeability. Their available water holding capacity is high. Roots penetrate to 60 inches or more. Runoff is slow and the erosion hazard due to wind is high. Map unit: 16 Colby loam, 3 to 5 percent slopes Description Category: SOI This is a deep well drained soil on upland hill and ridges. It formed in calcareous eolian deposits.Typically the surface is a pale brown loam about 10 in.thick.The underlying material is a very pale brown silt loam to a depth of 60 in. Permeability is moderate.Available water holding capacity is high.The effective rooting depth is 60 in. or more.Surface runoff is medium to rapid, and the hazard of water erosion is moderate. Map unit: 4 Aquolls and Aquepts, Flooded Description Category: SOI This map unit is in depressions in smooth plains and along bottoms of natural drainageways throughout the survey area.This unit consists of 55 percent Aquolls and 25 percent Aquepts soils.These soils are deep, poorly drained.They formed in recent alluvi um. The soils have a mildly to moderately alkaline loamy or clayey surface layer and underlying material that extends to a depth of 60 inches or more.The water table is at or near the surface, creating a hydric soil condition.The erosion hazard due to w ind is low. Map unit: 42 Nunn clay loam, 1 to 3 percent slopes Description Category: SOI The Nunn soil is a deep,well drained soil. It is formed on terraces and smooth plains in mixed eolian and alluvial deposits.The surface is a clay loam.The underlying material is clay loam and sandy loam. The soils have moderately slow permeability. T heir available water holding capacity is high. Roots penetrate to 60 inches or more. Runoff is slow and the erosion hazard due to wind is low.
