Bon and Roxbury soils contain less clay and have loamy control sections and are on slightly higher landscapes than the Clamo soils. Betts soil have a fine-loamy control section and do not have an aquic moisture regime and are on steep adjacent uplands. Durrstein soils have a natric horizon and are on similar landscapes with microrelief. James, Lamo, and Luton soils are on similar landscapes as the Clamo soil. James soils have carbonates at or near the surface and contain more salts.
Lamo soils have a fine-silty control section.
Luton soils do not have free carbonates to depths of 36 inches or more and do not contain gypsum. Surface runoff is slow or very slow. Permeability is slow. Principal crops are native hay, pasture, corn, and small grains. Spring farming operations are frequently delayed because of high water tables and flooding.
