There are no other soils currently in the same family. The Comus , Linden , and Pope series are similar soils in related families. Comus soils are from outside of LRR R. Linden and Pope soils have been commonly used in the southern portions of LRR R in MLRAs 140 and 144A. Comus soils formed in materials high in mica and are sandy loam or finer to a depth of 40 inches. Linden soils have 5YR or redder hue in the Bw horizon. Pope soils contain less feldspar and weatherable minerals and typically have finer texture in the substratum.
Occum soils are nearly level soils on flood plains, along rivers and streams.
Slope ranges from 0 to 3 percent. The soils formed in recent alluvium derived mostly from gneiss, granite, and schist. Mean annual temperature ranges from 45 to 54 degrees F., mean annual precipitation ranges from 35 to 50 inches, and the growing season ranges from 115 to 190 days. These are the Agawam , Enfield , Hadley , Haven , Hinckley , Lim , Limerick , Merrimac , Pootatuck , Rippowam , Saco , Suncook , Windsor , and Winooski soils on nearby landscapes. The moderately well drained Pootatuck and the poorly drained Rippowam soils are associated in a drainage sequence.
