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. PfA-Paxton fine sandy loam, 0 to 3 percent slopes. This soil is nearly level, deep, and well drained. It is on the tops of ridges and hills. Areas of this soil are typically rectangular and range from 5 to 25 acres. Most are about 10 acres. Typically, the surface layer is very dark grayish brown fine sandy loam about 8 inches thick. The subsoil is 14 inches thick. The upper 8 inches of the subsoil is yellowish brown fine sandy loam, and the lower 6 inches is olive yellow sandy loam. The substratum is pale olive, very firm and brittle gravelly sandy loam to a depth of 60 inches or more. Included with this soil in mapping are small areas of Woodbridge soils, areas where the substratum is gravelly loamy sand or gravelly loamy coarse sand, and areas where the substratum is at a depth of more than 36 inches. Also included are small areas with slopes of 3 to 8 percent and a few places where the surface layer and upper part of the subsoil are very fine sandy loam. Included areas make up about 20 percent of the unit. The permeability of this Paxton 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 is very friable and easily tilled. After prolonged rains, a water table between the depths of 16 and 22 inches is perched above the substratum. Root growth is restricted to a depth of about 22 inches by the very firm substratum. Most areas of this soil are used for hay, improved pasture, or cultivated crops. A few areas are in woodland, and the soil is well suited to trees. Some areas are used for homesites and other types of community development. This soil is well suited to row crops. Mixing crop residue and manure into the surface layer helps to maintain the organic matter content and tilth of the soil. The soil is well suited to hay and pasture (fig. 7). The main management concern is the prevention of overgrazing, which reduces the hardiness and density of desirable plants. Using proper stocking rates and restricted grazing during wet periods help to maintain plant densities and reduce surface compaction. The seasonal perched water table is the main limitation of the soil for community development, especially as a building site and a site for sanitary landfills. The slow permeability in the substratum is a limitation for septic tank absorption fields. Capability class: I. PfB-Paxton fine sandy loam, 3 to 8 percent slopes. This soil is gently sloping, deep, and well drained. It is on the tops and sides of ridges and hills. Areas of this soil are typically irregular in shape and range from 5 to 150 acres. Most are about 50 acres. Typically, the surface layer is very dark grayish brown fine sandy loam about 8 inches thick. The subsoil is 14 inches thick. The upper 8 inches of the subsoil is yellowish brown fine sandy loam, and the lower 6 inches is olive yellow sandy loam. The substratum is pale olive, very firm and brittle gravelly sandy loam to a depth of 60 inches or more. Included with this soil in mapping are small areas of Woodbridge soils and areas where the substratum is gravelly loamy sand or gravelly loamy coarse sand. In places the substratum is at a depth of more than 36 inches. Also included are areas with slopes of 0 to 3 percent. Included areas make up 20 percent of the unit. The permeability of this Paxton 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 is very friable and easily tilled. During and following rainy periods, a temporary water table is often between depths of 16 and 22 inches. Root growth is restricted to a depth of about 22 inches by the very firm substratum. Most areas of this soil are used for hay, improved pasture, or cultivated crops (fig. 8). A few areas are in woodland, and the soil is well suited to trees. Some areas are used for homesites or other types of community development. This soil is well suited to row crops, but erosion is a hazard. Management practices that help reduce runoff and control erosion include minimum tillage, using cover crops, and incorporating crop residue and manure into the surface layer. The soil is well suited to hay and pasture. The main management concern is the prevention of overgrazing, which compacts the surface layer and reduces the hardiness and density of plants. Using proper stocking rates and restricted grazing when the soil is wet help to maintain plant densities and reduces surface compaction. The seasonal perched water table is the main limitation of this soil for community development, especially as a building site or as a site for sanitary landfills. The slow permeability in the substratum of the soil is a limitation for septic tank absorption fields. Capability subclass: IIe. PfC-Paxton fine sandy loam, 8 to 15 percent slopes. This soil is moderately sloping, deep, and well drained. It is on the sides of ridges and hills. Areas of this soil range from about 5 to 150 acres. Most are about 50 acres. Typically, the surface layer is very dark grayish brown fine sandy loam about 8 inches thick (fig. 9). The subsoil is 14 inches thick. The upper 8 inches of the subsoil is yellowish brown fine sandy loam, and the lower 6 inches is olive yellow sandy loam. The substratum is pale olive, very firm and brittle gravelly sandy loam to a depth of 60 inches or more. Included with this soil in mapping are small areas of Woodbridge soils, areas where the substratum is gravelly loamy sand or gravelly loamy coarse sand, and areas where the substratum is at a depth of less than 20 inches or at a depth of more than 36 inches. Wet seep spots are common in this unit, and in a few places the surface layer and upper part of the subsoil are very fine sandy loam. Included areas make up about 20 percent of the unit.
