PLYMOUTH COUNTY, MASSACHUSETTS SOIL SURVEY UPDATE
Newfields Soils: Very deep, moderately well drained soils formed in loamy mantle, underlain by sandy glacial till and ice-contact deposits. Newfields soils are on uplands, moraines and ice-contact areas.
to Official Series Description
Newfields Pedon Description 2342701
Unit (s): 426A, 426B, 427A, 427B.
Classification: Coarse-loamy over sandy or sandy skeletal,
mixed, mesic, Oxyaquic Dystrochrepts.
Drainage Class: Moderately well drained.
Parent Material: Ice contact deposits and/or ablation till.
Permeability: Moderate throughout.
Available Water Holding Capacity: Moderate.
Soil Reaction: Extremely acid through slightly acid throughout.
Depth to Bedrock: Greater than 65 inches.
Seasonal High Watertable: Depth: 1.5 to 4 feet. Type: Apparent/Perched. Months: November to April.
Hydrologic Group: B.
Hydric Soil: No (may have hydric inclusions).
Flooding/Ponding Potential: Frequency and Type: None.
Potential Inclusions: Birchwood and Scituate soils are similar inclusions. Poorly drained Mattapoisett and Norwell soils are along drainageways. Well drained Canton, Montauk and Merrimac soils are on convex slopes.
Agriculture: Map units 426A and 426B are prime farmland soils. 427A and 427B are important agricultural map units. Irrigation is needed for optimal yield. The seasonal high water table may delay some practices during the spring and limit root growth.
Woodland: Well suited for woodland productivity.
Development: Major limitations related to the seasonal high watertable. Mounded septic systems are usually required. Newfields soils are mapped in ice contact areas and the substratum may consist of variable types of geologic sediments. Slowly permeable layers may result in slow percolation rates for on-site sewage disposal systems.
