Tomlin soil and landscape NC
Tomlin sandy clay loam, 10 to 15 percent slopes, moderately eroded (Iredell County, NC)
Setting
Major land resource area: Southern Piedmont (MLRA 136)
Landscape: Upland and hillslope on ridge
Landform position: Backslope
Elevation: 700 to 1,200 feet
Map Unit Composition
Tomlin and similar soils: Typically 80 percent, ranging from about 75 to 90 percent
Typical Profile
Tomlin
Surface layer:
0 to 10 inches; dark reddish brown sandy clay loam
Subsoil:
10 to 28 inches; dark red clay
28 to 48 inches; red clay loam
48 to 67 inches; red loam
Substratum:
67 to 80 inches; red loam
Components
Similar components:
• Clifford soils, which do not have a dark red subsoil like the Tomlin soil, in similar areas
Dissimilar components:
• Poplar Forest soils, which have a subsoil that is thinner than that of the Tomlin soil and that contains a high content of mica flakes, in similar areas
Soil Properties and Qualities
Available water capacity: Moderate (about 8.2 inches)
Slowest saturated hydraulic conductivity: Moderately high (about 0.6 in/hr)
Depth class: Very deep (more than 60 inches)
Depth to root-restrictive feature: More than 60 inches
Agricultural drainage class: Well drained
Depth to seasonal water saturation: More than 6 feet
Flooding hazard: None
Ponding hazard: None
Shrink-swell potential: Low
Runoff class: Medium
Surface fragments: None
Parent material: Saprolite derived from diorite, gabbro, diabase, and/or gneiss
Use and Management Considerations
Cropland
Suitability: Suited
Management concerns: Erodibility, tilth, and soil fertility
Management measures and considerations:
• Resource management systems that include conservation tillage, crop residue
management, stripcropping, and sod-based rotations help to prevent further erosion by stabilizing the soil, controlling surface runoff, and maximizing the infiltration of water.
• Incorporating crop residue into the soil or leaving residue on the soil surface helps to minimize clodding and crusting and maximize the infiltration of water.
• Restricting tillage to periods when the soil is not wet helps to minimize clodding and crusting and increases the infiltration of water.
• Applying lime and fertilizer according to recommendations based on soil tests helps to increase the availability of plant nutrients and maximize crop productivity.
