Wapping Soil Map Unit Description- RI

Soil Map Unit Description from the Soil Survey of Rhode Island

WbA—Wapping slit loam, 0 to 3 percent slopes.

This nearly level, moderately well drained soil is in depressions on the crests of glacial upland hills and in drainageways. Areas are irregular in shape and range mostly from 10 to 100 acres.

Typically the surface layer is very dark brown and very dark grayish brown silt loam 5 inches thick. The subsoil is 25 inches thick. The upper 14 inches is dark yellowish brown and yellowish brown silt loam, and the lower 11 inches is dark brown, mottled silt loam. The substratum extends to a depth of 60 inches or more. It is brown, mottled sandy loam to a depth of 37 inches and dark yellowish brown gravelly loamy sand at a depth of more than 37 inches.

Included with this soil in mapping are small areas of well drained Narragansett and Bridgehampton soils and poorly drained Leicester soils. Also included are small areas with stones on the surface. Included areas make up about 10 percent of this map unit.

The permeability of this soil is moderate in the surface layer and subsoil and moderate or moderately rapid in the substratum. Available water capacity is moderate, and runoff is slow. This soil has a seasonal high water table at a depth of about 20 inches from late fall through midspring. The soil is very strongly acid through medium acid.

The soil is suited to trees, but most areas are cleared and used for farming and openland wildlife habitat.

This soil is suited to cultivated crops. It dries out and warms slowly in the spring, limiting early planting and machinery operation, and artificial drainage is needed.

The use of cover crops and the return of crop residue to the soil help to maintain tilth and organic matter content.

This soil is suited to woodland wildlife habitat and openland wildlife habitat. It is poorly suited to wetland wildlife habitat because it is too dry in the summer. Capability subclass IIw; woodland group 3o.

WbB—Wapping silt loam, 3 to 8 percent slopes.

This gently sloping, moderately well drained soil is on the crests and side slopes of glacial upland hills. Areas range from 10 to 100 acres and are mostly irregular in shape.

Typically the surface layer is very dark grayish brown silt loam 5 inches thick. The subsoil is 25 inches thick. The upper 14 inches is dark yellowish brown and yellowish brown silt loam, and the lower 11 inches is dark brown, mottled silt loam. The substratum extends to a depth of 60 inches or more. It is brown, mottled sandy loam to a depth of 37 inches and dark yellowish brown gravelly loamy sand at a depth of more than 37 inches.

Included with this soil in mapping are small areas of well drained Narragansett and Bridgehampton soils and poorly drained Leicester soils. Also included are areas of soils with slopes of more than 8 percent. Included areas make up about 10 percent of this map unit.

The permeability of this soil is moderate in the surface layer and subsoil and moderate to moderately rapid in the substratum. Available water capacity is moderate, and runoff is medium. This soil has a seasonal high water table at a depth of about 20 inches from late fall through midspring. The soil is very strongly acid through medium acid.

This soil is suitable for community development. The main limitation for this use is the seasonal high water table. Onsite sewage disposal systems need special design and installation because of the wetness. If suit able outlets are available, subsurface drains can be used to help prevent wet basements. Roads and streets need careful design to prevent frost heaving. The use of straw bale sediment barriers and quickly establishing plant cover help to control erosion during construction.

The soil is suited to trees, but most areas are cleared and used for farming or openland wildlife habitat.

This soil is suited to cultivated crops. It dries out and warms up slowly in the spring, limiting early planting and machinery operation, and artificial drainage is needed. The use of cover crops, diversions, and stripcropping and the return of crop residue to the soil help to control erosion and maintain tilth and organic matter content.

WcB—Wapping very stony silt loam, 0 to 8 percent slopes.

This nearly level to gently sloping, moderately well drained soil is on side slopes and crests of glacial upland hills. Stones and boulders cover 2 to 10 percent of the surface. Areas are irregular in shape and range mostly from 10 to 100 acres.

Included with this soil in mapping are small areas of well drained Narragansett and Bridgehampton soils and poorly drained Leicester soils. Included areas make up about 10 percent of this map unit.

The permeability of this soil is moderate in the surface layer and subsoil and moderate or moderately rapid in the substratum. Available water capacity is moderate, and runoff is slow to medium. This soil has a seasonal high water table at a depth of about 20 inches from late fall through midspring. The soil is very strongly acid through medium acid.

The soil is suited to trees, and most areas are in woodland. A small acreage is cleared and used for pasture.

This soil is suitable for community development. The main limitation for this use is the seasonal high water table. Onsite sewage disposal systems need special design and installation because of wetness. If suitable outlets are available, subsurface drains can be used to help prevent wet basements. Roads and streets need careful design to prevent frost heaving, and the stones and boulders on the surface need to be removed for landscaping. The use of straw bale sediment barriers and quickly establishing plant cover help to control erosion during construction.

The stones and boulders on the surface make this soil unsuitable for cultivated crops and severely hinder the use of farming equipment. The hazard of erosion is slight to moderate.

This soil is suited to woodland wildlife habitat. It is poorly suited to openland wildlife habitat or wetland wild life habitat. Capability subclass VIs; woodland group 3o.

WdB—Wapping extremely stony silt loam, 0 to 8 percent slopes.

This nearly level to gently sloping, moderately well drained soil is on side slopes and crests of glacial upland hills. Stones and boulders cover 10 to 35 percent of the surface. Areas are irregular in shape and range mostly from 10 to 75 acres.

Typically the surface layer is very dark grayish brown silt loam 5 inches thick. The subsoil is 25 inches thick. The upper 14 inches is dark yellowish brown and yellow ish brown silt loam, and the lower 11 inches is dark brown, mottled silt loam. The substratum extends to a depth of 60 inches or more. It is brown, mottled sandy loam to a depth of 37 inches and dark yellowish brown gravelly loamy sand at a depth of more than 37 inches.

Included with this soil in mapping are small areas of well drained Narragansett and Bridgehampton soils and poorly drained Leicester soils. Also included are small areas with slopes of more than 8 percent. Included areas make up about 10 percent of this map unit.

The permeability of this soil is moderate in the surface layer and subsoil and moderate or moderately rapid in the substratum. Available water capacity is moderate, and runoff is slow to medium. This soil has a seasonal high water table at a depth of about 20 inches from late fall through midspring. The soil is very strongly acid through medium acid.

This soil is suitable for community development but is limited by the seasonal high water table and the stones and boulders on the surface. Onsite sewage disposal systems need special design and installation because of the wetness. If suitable outlets are available, subsurface drains can be used to help prevent wet basements. Roads and streets need careful design to prevent frost heaving, and the stones and boulders need to be re moved for landscaping. The use of straw bale sediment barriers and quickly establishing plant cover help to control erosion during construction.

This soil is suited to trees, and most areas are wooded. The main limitation for woodland is the stones and boulders on the surface, which hinder planting and harvesting equipment.

The stones and boulders make this soil unsuitable for farming and the use of equipment impractical.

This soil is suited to woodland wildlife habitat. It is not suited to openland wildlife habitat; it is poorly suited for wetland wildlife habitat because it is too dry in the summer. Capability subclass VIIs; woodland group 3x.
