Inclusions: Barnstable, Windsor, Hinckley and Carver soils
are similar inclusions. . Moderately well drained Sudbury and
Deerfield soils are on lower elevations. Poorly drained Wareham
and Pipestone soils are along drainageways.
Soil Suitability:
Agriculture: Map units 254A and 254B are prime farmland
soil map units. 254C is an important farmland map unit.
Irrigation is needed for optimal production.
Woodland: Well suited for woodland.
Development: Merrimac soils have few limitations for
development. They are associated with aquifer recharge areas and
measures should be taken to protect the aquifer.
