There are no other soils in this family. The Chautauqua , Pittstown , Pompton , Rainbow , Sutton , Wapping , Watchaug , Wilbraham , and Woodbridge soils are in closely related families. Chautauqua, Pompton, Sutton, Wapping, and Watchaug soils do not have a dense substratum. Pittstown, Rainbow, and Woodbridge soils have hue yellower than 7.5YR in the B horizon. Wilbraham soils are wetter with iron depletions throughout the B horizon.
Ludlow soils are nearly level to strongly sloping and are on till plains, hills, and drumlins.
Slope ranges from 0 to 15 percent. The soils formed in acid till derived mostly from reddish sandstone, shale, and conglomerate with some basalt. Mean annual temperature ranges from 45 to 52 degrees F., mean annual precipitation ranges from 40 to 50 inches, and the growing season ranges from 130 to 185 days. These are the Berlin , Birchwood , Branford , Broadbrook , Cheshire , Ellington , Hartford , Holyoke , Manchester , Menlo , Narragansett , Penwood , Poquonock , Rainbow , Wapping , Watchuag, Wethersfield , Yalesville , and Wilbraham soils on nearby landscapes. The well drained Wethersfield, poorly drained Wilbraham, and the very poorly drained Menlo soils are associated in a drainage sequence.
