Soil Survey of Bristol County, Massachusetts

SOUTHERN PART

The following Map Unit Description is from the 1981 Soil Survey of Bristol County, Southern Part. Please note: map unit symbols are DIFFERENT for Bristol South and Bristol North reports, do NOT use these descriptions for Bristol North.

WrA-Woodbridge fine sandy loam, 0 to 3 percent slopes. This soil is nearly level, deep, and moderately well drained. It is on hilltops and at the base of long slopes. Areas of this soil are irregular in shape and range from 5 to 60 acres. Most are about 20 acres.

Typically, the surface layer is dark brown fine sandy loam about 9 inches thick. The subsoil is brown fine sandy loam and mottled gravelly fine sandy loam 18 inches thick. The substratum is light brownish gray, very firm, mottled gravelly sandy loam to a depth of 60 inches or more.

Included with this soil in mapping are areas where the substratum is gravelly loamy sand, gravelly loamy coarse sand, and gravelly coarse sandy loam. Also included are convex areas of Paxton soils and areas of Ridgebury soils in depressions and along drainageways. In a few areas stones and boulders cover up to 3 percent of the surface, and in a few others the surface layer and upper part of the subsoil are very fine sandy loam. A few areas have slopes of 3 to 8 percent. Included areas make up about 20 percent of the unit.

The permeability of this Woodbridge soil is moderate in the surface layer and subsoil and slow or very slow in the substratum. Available water capacity is moderate. The surface layer of this soil is friable and is easily tilled under proper moisture conditions. After prolonged rains, a water table between the depths of 20 and 27 inches is perched above the substratum. Root growth is restricted to a depth of about 27 inches by the very firm substratum.

Most areas of this soil are used for farming. Some areas are in woodland, and the soil is well suited to trees. A few areas are used for homesites and other types of community development.

This soil is suited to row crops. A seasonal high water table is the main limitation. The main management practices include using drainage and cover crops and incorporating crop residue and manure into the surface layer.

The soil is well suited to hay and pasture. Use of proper stocking rates, deferred grazing, pasture rotation, and restricted grazing when the soil is wet help to maintain the hardiness and density of pasture plants and prevent surface compaction.

The seasonal perched water table is the main limitation of this soil for community development, especially as a building site and as a site for sanitary landfills and septic tank absorption fields. The slow permeability in the substratum also limits the soil for septic tanks.

Capability subclass: IIw.

WrB-Woodbridge fine sandy loam, 3 to 8 percent slopes. This soil is gently sloping, deep, and moderately well drained. It is on the tops and sides of hills. Areas of this soil are irregular in shape and range from 5 to 60 acres. Most are about 30 acres.

Typically, the surface layer is dark brown fine sandy loam about 9 inches thick. The subsoil is brown fine sandy loam and mottled gravelly fine sandy loam 18 inches thick. The substratum is light brownish gray, very firm, mottled gravelly sandy loam to a depth of 60 inches or more.

Included with this soil in mapping are areas where the substratum is gravelly loamy sand, gravelly loamy coarse sand, and gravelly coarse sandy loam. Also included are convex areas of Paxton soils and areas of Ridgebury soils in depressions and along drainageways. In a few areas stones and boulders cover up to 3 percent of the surface, and in a few others the surface layer and upper part of the subsoil are very fine sandy loam. A few areas have slopes of 0 to 3 percent. Included areas make up about 20 percent of the unit.

The permeability of this Woodbridge soil is moderate in the surface layer and subsoil and slow or very slow in the substratum. Available water capacity is moderate. The surface layer of this soil is friable and is easily tilled under proper moisture conditions. After prolonged rains, a water table between the depths of 20 and 27 inches is perched above the substratum. Root growth is restricted to a depth of about 27 inches by the very firm substratum.

Most areas of this soil are used for farming (fig. 15). Some areas are in woodland, and the soil is well suited to trees. A few are used for homesites and other types of community development.

This soil is suited to row crops. A seasonal high water table is the main limitation, and erosion is a hazard. The main management practices include using drainage, using cover crops, and incorporating crop residue and manure into the surface layer.

The soil is well suited to hay and pasture. Use of proper stocking rates, deferred grazing, pasture rotation, and restricted grazing when the soil is wet help to maintain the hardiness and density of pasture plants and prevent surface compaction.

The seasonal perched water table is the main limitation of the soil for community development, especially as a building site and as a site for septic tank absorption fields and sanitary landfills. The slow permeability in the substratum is also a limitation for septic tanks.

Capability subclass: IIw.

WsB-Woodbridge very stony fine sandy loam, 0 to 8 percent slopes. This soil is nearly level and gently sloping, deep, and moderately well drained. It is on the tops and sides of hills. Stones and boulders cover from less than 1 percent to 3 percent of the surface. Areas of this soil are irregular in shape and range from 5 to 200 acres. Most are about 100 acres.

Typically, the surface layer is dark brown fine sandy loam about 9 inches thick. The subsoil is brown fine sandy loam and mottled gravelly fine sandy loam 18 inches thick. The substratum is light brownish gray, very firm, mottled sandy loam to a depth of 60 inches or more.

Included with this soil in mapping are areas where the substratum is gravelly loamy sand, gravelly loamy coarse sand, or gravelly coarse sandy loam. Also included are convex areas of Paxton soils and areas of Ridgebury soils in depressions and along drainageways. In a few areas stones and boulders cover up to 12 percent of the surface, and a few others have slopes of more than 8 percent. Included areas make up about 20 percent of the unit.

The permeability of this Woodbridge soil is moderate in the surface layer and subsoil and slow or very slow in the substratum. Available water capacity is moderate. The surface layer of this soil is friable and is easily tilled if the stones are removed. After prolonged rains, a water table between the depths of 20 and 27 inches is perched above the substratum. Root growth is restricted to a depth of about 27 inches by the very firm substratum.

Most areas of this soil are in woodland, and the soil is well suited to trees. Some areas are used for pasture. A few are used for homesites and other types of community development.

The stones and boulders on the surface limit the use of most types of equipment and make this soil poorly suited to row crops. A seasonal high water table is also a major limitation for crops.

The soil is suited to hay and pasture, but the limitations to the use of equipment make it difficult to seed and fertilize. Use of proper stocking rates, deferred grazing, pasture rotation, and restricted grazing when the soil is wet help to maintain the hardiness and density of pasture plants and prevent surface compaction.

The seasonal perched water table is the main limitation of the soil for community development, especially as a building site and as a site for septic tank absorption fields and sanitary landfills. The slow permeability in the substratum is also a limitation for septic tanks.

Capability subclass: VIs.

WtB-Woodbridge extremely stony fine sandy loam, 0 to 8 percent slopes. This soil is nearly level and gently sloping, deep, and moderately well drained. It is on the tops and sides of hills. Stones and boulders cover 3 to 15 percent of the surface. Areas of this soil are irregular in shape and range from 5 to 200 acres. Most are about 100 acres.

Typically, the surface layer is dark brown fine sandy loam about 4 inches thick. The subsoil is brown fine sandy loam and mottled gravelly fine sandy loam 23 inches thick. The substratum is light brownish gray, very firm, mottled gravelly sandy loam to a depth of 60 inches or more.

Included with this soil in mapping are areas where the substratum is gravelly loamy sand, gravelly loamy coarse sand, or gravelly coarse sandy loam. Also included are convex areas of Paxton soils and areas of Ridgebury soils in depressions and along drainageways. In a few areas stones and boulders cover up to 25 percent of the surface, and a few others have slopes of more than 8 percent. Included areas make up about 20 percent of the unit.

The permeability of this Woodbridge soil is moderate in the surface layer and subsoil and slow or very slow in the substratum. Available water capacity is moderate. The surface layer of this soil is friable. After prolonged rains, a water table between the depths of 20 and 27 inches is perched above the substratum. Root growth is restricted to a depth of about 27 inches by the very firm substratum.

Most areas of this soil are in woodland. Some areas are used for pasture. A few areas are used for homesites and other types of community development.

The stones and boulders on the surface limit the use of most types of equipment and make this soil poorly suited to farming. A seasonal high water table is also a major limitation. The soil is suited to trees, but the stones and boulders also limit the use of timber equipment.

The seasonal perched water table is the main limitation of the soil for community development, especially as a building site and as a site for septic tank absorption fields and sanitary landfills. The slow permeability in the substratum is also a limitation for septic tanks.

Capability subclass: VIIs.
