Soil Survey of Lincoln County, West Virginia Interpretive Groups Land capability classification: 6e Woodland ordination symbol: 4R on north aspects and 3R on south aspects Prime farmland: No Hydric soil: No Sm—Skidmore gravelly sandy loam, frequently flooded Setting Landscape position: On narrow flood plains along the tributaries of streams; throughout the southern part of the county Composition Skidmore and similar soils: 85 percent Dissimilar inclusions: 15 percent Typical Profile Surface layer: 0 to 10 inches—brown gravelly sandy loam Subsoil: 10 to 22 inches—dark yellowish brown very gravelly sandy loam 22 to 30 inches—dark yellowish brown extremely cobbly sandy loam Substratum: 30 to 65 inches—dark yellowish brown and brown extremely cobbly loamy sand Soil Properties and Qualities Drainage class: Well drained Permeability: Moderately rapid Available water capacity: Low Depth to a seasonal high water table: 36 to 48 inches Flooding: Frequent Shrink-swell potential: Low Hazard of erosion: Slight Slope class: Nearly level Stoniness: None Rockiness: 15 to 35 percent Natural fertility: Medium Reaction: In unlimed areas, moderately acid or slightly acid throughout Organic matter content in the surface layer: Moderate Surface runoff: Negligible Depth to bedrock: More than 60 inches Inclusions Limiting inclusions: Soils that are less than 60 inches deep over bedrock Lobdell soils Soils that have more than 35 percent gravel in the surface layer Use and Management Uses: Most areas of this Skidmore soil are used as woodland or pasture. Cropland Suitability: Suited 128
Soil Survey of Lincoln County, West Virginia Management considerations: The flooding delays fieldwork and damages crops. The droughtiness and poor tilth are management concerns. Runoff from the adjacent hillsides can cause scouring and sedimentation in areas of this soil. Protecting the soil against flooding and maintaining a drainage system help to prevent crop damage. Because of the limited available water capacity, most crops should be irrigated. Applying a system of conservation tillage, growing cover crops, including grasses and legumes in the cropping sequence, and returning crop residue to the soil help to improve and maintain tilth and to maintain the content of organic matter. The installation of diversions helps to control runoff and overwash from adjacent upland backslopes. Pasture and Hayland Suitability: Well suited Management considerations: The flooding deposits debris on the grassland. Maintaining natural fertility is a management concern. The species selected for planting should be those that can provide high-quality forage and satisfactory ground cover and are tolerant of the flooding. Proper stocking rates, pasture rotation, timely deferment of grazing, and applications of fertilizer help to keep the pasture in good condition. Woodland Potential productivity: High Management considerations: The seedling mortality rate and plant competition are management concerns. Planting when the soil is moist can reduce the seedling mortality rate. Exposing the soil immediately prior to the production of a seed crop or prior to artificial seeding helps desirable tree seedlings to become established quickly and to compete better with undesirable vegetation. Community Development Suitability: Unsuited Management considerations: The flooding is a management concern. Constructing roads, buildings, and houses on elevated, well compacted fill material helps to prevent the damage caused by flooding. Interpretive Groups Land capability classification: 2w Woodland ordination symbol: 8W Prime farmland: No Hydric soil: No Ud—Udorthents, smoothed Setting Landscape position: Excavated, graded, filled, and revegetated areas in the uplands; throughout the county Composition Udorthents: 85 percent Limiting inclusions: 15 percent 129
