Soil Survey of Lincoln County, West Virginia GmE—Gilpin-Matewan complex, 25 to 35 percent slopes, very stony Setting Landscape position: On summits, shoulders, and nose slopes of ridges; in areas underlain by interbedded sandstone and shale of the Conemaugh Formation Note: The Gilpin and Matewan soils occur as areas so intermingled and small that mapping them separately is impractical. Composition Gilpin, Matewan, and similar soils: 75 percent Dissimilar inclusions: 25 percent Typical Profile Gilpin Organic layers: 0 to 2 inches—slightly decomposed leaf litter 2 to 3 inches—moderately decomposed, very dark gray leaf litter Surface layer: 3 to 6 inches—very dark grayish brown silt loam Subsoil: 6 to 16 inches—yellowish brown channery silt loam 16 to 28 inches—brown channery silty clay loam Bedrock: 28 to 33 inches—interbedded soft shale, siltstone, and fine grained sandstone 33 inches—hard, fine grained sandstone Matewan Organic layers: 0 to 3 inches—slightly decomposed leaf litter 3 to 4 inches—moderately decomposed, very dark brown leaf litter Surface layer: 4 to 6 inches—olive brown sandy loam Subsoil: 6 to 9 inches—olive brown channery sandy loam 9 to 26 inches—yellowish brown channery sandy loam Substratum: 26 to 34 inches—yellowish brown and dark yellowish brown extremely channery sandy loam Bedrock: 34 inches—hard sandstone Soil Properties and Qualities Drainage class: Gilpin—well drained; Matewan—well drained or somewhat excessively drained Permeability: Gilpin—moderate; Matewan—moderately rapid or rapid Available water capacity: Gilpin—moderate; Matewan—low Depth to a seasonal high water table: More than 72 inches Flooding: None Shrink-swell potential: Low Hazard of erosion: Severe 48
Soil Survey of Lincoln County, West Virginia Slope class: Steep Stoniness: 1 to 3 percent of the surface covered by stones Rockiness: None Natural fertility: Medium Reaction: In unlimed areas, extremely acid to moderately acid throughout Organic matter content in the surface layer: Moderate Surface runoff: High Depth to bedrock: 20 to 40 inches Inclusions Limiting inclusions: Shallow soils Wharton soils Soils that have more clay in the subsoil and are moderately well drained Use and Management Uses: Most areas of this map unit are used as woodland. Some areas have been cleared and are used as hayland or pasture. Cropland Suitability: Unsuited Management considerations: The steepness of slope, a severe hazard of erosion, and the stones on the soil surface are the major management concerns. Crop rotations that include grasses and legumes or small grain, a system of conservation tillage, cover crops and green manure crops, and crop residue management help to prevent excessive erosion and to maintain fertility and tilth. Removal of surface stones reduces equipment wear and helps to increase crop yields. Pasture and Hayland Suitability: Unsuited to hay; suited to pasture Management considerations: The surface stones interfere with the operation of harvesting equipment in areas of hayland. Erosion is a severe hazard if the sod is removed by overgrazing. Proper stocking rates, a planned grazing system, and deferred grazing during wet periods help to keep the pasture in good condition. Woodland Potential productivity: Moderate Management considerations: Seedling mortality caused by droughtiness, plant competition, and the severe erosion hazard are management concerns. Because of the stoniness, machine planting is not practical in areas of this map unit. Mulching seedlings, when practical, and using north-facing slopes for plantations, where possible, reduce the seedling mortality rate. Exposing the soil immediately prior to the production of a seed crop or prior to artificial seeding can help desirable tree seedlings to become established quickly and to compete better with undesirable vegetation. The hazard of erosion can be minimized by building logging roads and trails on the contour; seeding roads, landings, and areas that have been cut and filled to perennial grasses and legumes; and installing water bars and culverts. Because of stones at the surface, wheeled skidders with high clearance should be operated at a reduced speed over carefully chosen routes. 49
