PLYMOUTH COUNTY, MASSACHUSETTS SOIL SURVEY UPDATE

Newport Soils: Very deep well drained soils formed in compact glacial till dominated by dark colored (Carboniferous) minerals. Newport soils are on till plains, smooth convex sideslopes of uplands and on drumlins. Newport soils are mapped primarily in the northern portion of the County.

    Taxonomic Classification: Coarse - loamy, mixed, mesic, Oxyaquic Haplorthods.
    Drainage Class: Well drained.
    Parent Material: Dense glacial till derived from dark colored sedimentary rocks.
    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 Pittstown, Scituate, and Woodbridge soils are on concave and level slopes. Poorly drained Norwell, and Ridgebury soils are along drainageways. Also included are soil which have bedrock within 65 inches.

    Soil Suitability:

    Agriculture: Map unit 325B is a prime farmland soil. Map units 325C, 326C and 326B 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.
