The growing season ranges from 110 to 180 days. These are the moderately well drained Dartmouth , the somewhat poorly and poorly drained Raynham , the poorly drained Binghamville , and the poorly and very poorly drained Birdsall soils on associated landscapes. The Agawam , Enfield , Haven , Ninigret , Subdury, and Tisbury soils are in similar terrace positions, but formed in loamy over sandy materials. The Deerfield , Merrimac , and Windsor soils are in similar terrace positions, but formed in sandy or gravelly material. The Hadley , Limerick , Occum , Ondawa , Podunk , Pootatuck , Rippowam , Rumney , and Winooski soils are on adjacent flood plains.
Permeability is moderate in the solum and moderately slow or slow in the substratum.
Most areas of less than 15 percent slopes have been cleared of trees and are used for growing hay, pasture, and corn. Some areas are used for potatoes, sweet corn, vegetables and other cash crops. Woodlands are white, red, and black oaks, sugar maple, ash, black, yellow, and white birches, beech, white pine, and hemlock. The series is of limited extent. Grafton County, New Hampshire, 1987.
