Broadbrook Soils

Soil Map Unit Description from the RI Soil Survey Report

BrA - Broadbrook slit loam, 0 to 3 percent slopes.

Link to Official Soil Series Description for Broadbrook Soils

This nearly level, well drained soil is on the crests of upland hills and drumlins. Areas are oval and mostly range from 5 to 80 acres.

Typically the surface layer is dark brown silt loam about 9 inches thick. The subsoil is yellowish brown and light olive brown silt loam 27 inches thick. The substratum is light yellowish brown fine sandy loam to a depth of 60 inches or more.

Included with this soil in mapping are small areas of well drained Narragansett, Paxton, and Newport soils and moderately well drained Rainbow, Pittstown, and Woodbridge soils. Also included are small areas of soils that have slopes of more than 3 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 slow or very slow in the substratum. Available water capacity is moderate, and runoff is slow. This soil is very strongly acid through medium acid.

This soil is suitable for community development. The main limitation is the slow or very slow permeability of the substratum. Onsite sewage disposal systems need special design and installation, and roads and streets need careful design to prevent frost heaving. Steep slopes of excavations slump when saturated. Where out lets are available, footing drains help prevent wet basements. Quickly establishing plant cover and the use of mulch help to control erosion during construction.

This soil is suited to cultivated crops, and most areas are farmed. 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 trees, woodland wildlife habitat, and openland wildlife habitat. It is too dry to provide wetland wildlife habitat. Capability class I woodland group 3o.

BrB - Broadbrook slit loam, 3 to 8 percent slopes.

Link to Official Soil Series Description for Broadbrook Soils

This gently sloping, well drained soil is on the side slopes of glacial upland hills and drumlins. Areas are irregular in shape and mostly range from 6 to 80 acres.

Typically the surface layer is dark brown silt loam about 9 inches thick. The subsoil is yellowish brown and light olive brown silt loam 27 inches thick. The substratum is light yellowish brown fine sandy loam to a depth of 60 inches or more.

Included with this soil in mapping are small areas of well drained Narragansett, Newport, and Paxton soils and moderately well drained Rainbow, Pittstown, and Woodbridge soils. Also included are small areas of soils that have 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 slow or very slow in the substratum. Available water capacity is moderate, and runoff is medium. This soil is very strongly acid through medium acid.

This soil is suitable for community development. The main limitation is the slow or very slow permeability of the substratum. Onsite sewage disposal systems need special design and installation to prevent effluent from seeping to the surface, and roads and streets need careful design to prevent frost heaving. Steep slopes of excavations slump when saturated. Footing drains help prevent wet basements. The use of siltation basins and straw bale sediment barriers and quickly establishing plant cover help to control erosion during construction.

Most areas of this soil are used for farming, a use to which the soil is suited. The hazard of erosion is moderate. Stripcropping, the use of diversions and cover crops, and the return of crop residue to the soil help to maintain tilth and organic matter content and control erosion.

This soil is suited to trees, woodland wildlife habitat, and openland wildlife habitat. This soil is too dry to provide wetland wildlife habitat. Capability subclass IIe; woodland group 3o.

BsB - Broadbrook very stony silt loam, 0 to 8 percent slopes.

Link to Official Soil Series Description for Broadbrook Soils

This nearly level to gently sloping, well drained soil is on crests and side slopes of glacial upland hills and drumlins. Stones and boulders cover 2 to 10 percent of the surface of the soil. Areas are oval and mostly range from 5 to 80 acres.

Typically the surface layer is dark brown silt loam about 9 inches thick. The subsoil is yellowish brown and light olive brown silt loam 27 inches thick. The substratum is light yellowish brown fine sandy loam to a depth of 60 inches or more.

Included with this soil in mapping are small areas of well drained Narragansett, Charlton and Paxton soils and moderately well drained Rainbow and Woodbridge soils. A included are small areas of soils that have slopes of more than 8 percent and soils that do not have 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 slow or very slow in the substratum. Available water capacity is moderate, and runoff is slow to medium. This soil is very strongly acid through medium acid.

This soil is suited to trees and pasture, and most areas are in woodland or pasture grasses and legumes.

This soil is suitable for community development but is limited by the slow or very slow permeability of the substratum and the stony surface. Onsite sewage disposal systems need special design and installation to prevent effluent from seeping to the surface, and roads and streets need careful design to prevent frost heaving. Removal of stones and boulders is necessary for landscaping. The use of straw bale sediment barriers and siltation basins and quickly establishing plant cover help to control erosion during construction.

The stony surface makes this soil suited to cultivated crops and severely hinders the use of farming equipment. The hazard of erosion is moderate, but maintaining a permanent plant cover helps to control this hazard.

This soil is suitable for woodland wildlife habitat. Stoniness limits the suitability for openland wildlife habitat. The soil is too dry to provide wetland wildlife habitat. Capability subclass VIs; woodland group 3o.
