PLYMOUTH COUNTY, MASSACHUSETTS SOIL SURVEY UPDATE

Broadbrook Soils: Very deep, well drained soil formed in silty eolian sediments underlain by loamy dense glacial till. Broadbrook soils are on smooth, convex topslopes and upper sideslopes of drumlins and glaciated hills.

Map Unit (s): 340B, 340C, 340D, 341B, 341C, 341D
Map Phases:

Taxonomic Classification: Coarse - loamy, mixed, mesic, Oxyaquic Dystrochrepts.
Drainage Class: Well drained.
Parent Material: Eolian silt and very fine sand underlain by dense glacial till.
Permeability: Moderate in the solum, slow or very slow in the dense substratum.
Available Water Holding Capacity: Moderate.
Soil Reaction: Very strongly acid to moderately acid throughout. .
Depth to Bedrock: Greater than 65 inches.
Seasonal High Watertable: Depth: 2.5 to 4 feet.
Type: Perched
Months: January to May.
Hydrologic Group: C.
Hydric Soil: No.
Flooding/Ponding Potential: Frequency and Type: None.
Potential Inclusions: Paxton and Montauk soils are similar inclusions. Moderately well drained Scituate, Birchwood, and Woodbridge soils are on concave slopes and lower elevations. Poorly drained Norwell, Sippican, and Ridgebury soils are in depressions and along drainageways.

Soil Suitability:

Agriculture: Map unit 340B is a prime farmland soil. Map units 340C, 341C and 341B are important farmland soils.

Woodland: Well suited for woodland.

Development: Major limitations related to slow permeability in the dense till substratum. Large surface and subsurface stones and boulders may interfere with excavation. Erosion hazards are likely during development, measures should be taken to prevent erosion.
