The soils formed in silty alluvium. Climate is subhumid. Mean annual temperature ranges from 45 to 52 degrees F, and mean annual precipitation ranges from 18 to 26 inches. These include the competing Lamo soils and the Alcester , Bon , and Clamo soils. Lamo and Clamo soils are on similar landscapes.
Clamo soils contain more clay in the control section.
Alcester and Bon soils are better drained and on higher positions. Alcester soils are leached of carbonates to greater depths and do not have visible salts. Poorly drained and somewhat poorly drained. Surface runoff is slow or very slow. Permeability is moderate or moderately slow in the solum and moderately slow or slow in the underlying material.
