Scio Soils

Soil Map Unit Description from the RI Soil Survey Report

ScA—Scio silt loam, 0 to 3 percent slopes.

Link to Official Soil Series Description for Scio Soils

This nearly level, moderately well drained soil is in depressions of glacial till plains. Areas are long and narrow and range mostly from 5 to 20 acres.

Typically the surface layer is very dark grayish brown silt loam about 9 inches thick. The subsoil is 22 inches thick. The upper 6 inches is dark brown silt loam. The lower 16 inches is yellowish brown and light olive brown, mottled silt loam. The substratum extends to a depth of 60 inches or more. The upper part is olive gray, mottled silt loam. The lower part is grayish brown, mottled fine sandy loam.

included with this soil in mapping are small areas of well drained to moderately well drained Bridgehampton soils, moderately well drained Ninigret and Tisbury soils, and poorly drained Rumney and Raypol soils. Also included are small areas of soils that have slopes of more than 3 percent. Included areas make up about 10 per cent of this map unit.

The permeability of this soil is moderate in the surface layer and subsoil and slow through rapid in the substratum. Available water capacity is high, 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 above a depth of 40 inches and strongly acid through slightly acid below a depth of 40 inches.

The soil is suitable for community development but is limited by the seasonal high water table. Onsite sewage disposal systems need special design and installation. 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. Quickly establishing plant cover helps to control erosion during construction.

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

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 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 summer. Capability subclass IIw; woodland group 3o.

SdB—Scio very stony slit loam, 0 to 8 percent slopes.

Link to Official Soil Series Description for Scio Soils

This nearly level to gently sloping, moderately well drained soil is on glacial till plains. Stones and boulders cover 2 to 10 percent of the surface. Areas are irregular in shape and range mostly from 5 to 30 acres.

Typically the surface layer is very dark grayish brown silt loam about 9 inches thick. The subsoil is 22 inches thick. The upper 6 inches is dark brown silt loam, and the lower 16 inches is yellowish brown and light olive brown, mottled silt loam. The substratum extends to a depth of 60 inches or more. It is gray, mottled silt loam in the upper part and grayish brown, mottled fine sandy loam in the lower part.

Included with this soil in mapping are small areas of well drained to moderately well drained Bridgehampton soils and moderately well drained Wapping, Tisbury, and Sudbury soils. Also included are small areas of soils that do not have stones or boulders on the surface. Included areas make up abut 10 percent of this map unit.

The permeability of this soil is moderate in the surface layer and subsoil and slow through rapid in the substratum. Available water capacity is high, and runoff is slow or 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. Onsite sewage disposal systems need special design and installation. 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.

This soil is suited to trees, and most areas are in woodland.

The soil is not suited to cultivated crops. The stones and boulders on the surface severely hinder the use of farming equipment.

This soil is suited to woodland wildlife habitat. It is not suited to openland wildlife habitat. The soil is poorly suited to wetland wildlife habitat because it is too dry in summer. Capability subclass VIs; woodland group 3o.
