Soil Survey of Lincoln County, West Virginia Available water capacity: Moderate Depth to a seasonal high water table: 18 to 30 inches Flooding: None Shrink-swell potential: Low Hazard of erosion: Slight Slope class: Nearly level Stoniness: None Rockiness: None Natural fertility: Medium Reaction: In unlimed areas, extremely acid to neutral in the A and BA horizons and extremely acid to strongly acid in the Bt and C horizons Organic matter content in the surface layer: Moderate Surface runoff: Negligible Depth to bedrock: More than 60 inches Inclusions Limiting inclusions: Soils with slopes of more than 3 percent Soils that have been disturbed by earthmoving equipment Guyan soils Use and Management Uses: Most areas of this Cotaco soil are used for hay or pasture. A few areas are wooded. Cropland Suitability: Suited Management considerations: The flooding may damage crops early in the growing season. The seasonal wetness may delay tillage and planting in the spring. Most crops adapted to the survey area can be grown if an adequate drainage system is installed and flooding is controlled. Pasture and Hayland Suitability: Suited Management considerations: Grazing when the soil is too wet causes surface compaction and poor tilth and damages the sod. Unrestricted access to streams by livestock causes streambank erosion and water pollution. Proper stocking rates, a planned grazing system, and deferred grazing during wet periods help to keep the pasture in good condition. Streambanks should be fenced. Access to streams by livestock should be limited to protected crossings. Woodland Potential productivity: Moderately high Management considerations: Plant competition is severe if openings are made in the canopy. Competing vegetation generally can be controlled by mechanical means. Community Development Suitability: Poorly suited Management considerations: The seasonal wetness limits excavation and trafficability and may delay construction activities in the winter and spring. 32
Soil Survey of Lincoln County, West Virginia Because the soil is soft when wet, road pavement is subject to cracking and buckling under heavy loads. Buildings can be constructed on well compacted fill material that raises the site a sufficient distance above the water table. Constructing roads on raised fill material and installing a drainage system help to prevent the damage caused by wetness. Land capability classification: 2w Woodland ordination symbol: 4A Prime farmland: Yes Hydric soil: No Interpretive Groups CoB—Cotaco loam, 3 to 8 percent slopes Setting Landscape position: On low terraces along the major streams; throughout the county Composition Cotaco and similar soils: 80 percent Dissimilar inclusions: 20 percent Typical Profile Surface layer: 0 to 8 inches—brown loam Subsoil: 8 to 12 inches—yellowish brown loam 12 to 17 inches—yellowish brown, mottled loam 17 to 28 inches—brownish yellow, mottled clay loam 28 to 39 inches—brownish yellow and light gray clay loam Substratum: 39 to 50 inches—brownish yellow and light gray loam 50 to 65 inches—brownish yellow and light gray channery loam Soil Properties and Qualities Drainage class: Moderately well drained Permeability: Moderate Available water capacity: Moderate Depth to a seasonal high water table: 18 to 30 inches Flooding: None Shrink-swell potential: Low Hazard of erosion: Slight Slope class: Gently sloping Stoniness: None Rockiness: None Natural fertility: Medium Reaction: In unlimed areas, extremely acid to neutral in the A and BA horizons and extremely acid to strongly acid in the Bt and C horizons Organic matter content in the surface layer: Moderate Surface runoff: Very low Depth to bedrock: More than 60 inches 33
