The mean annual soil temperature ranges from about 47 to 53 degrees F. EC is less than 4 mmhos throughout. Coarse fragments range from 0 to 15 percent pebbles throughout the soil but are typically less than 5 percent. Reaction is neutral or mildly alkaline. Texture is clay loam or loam with 18 to 35 percent clay and more than 15 but less than 35 percent fine sand or coarser. The Bt is typically noncalcareous, but some pedons are calcareous due to recharge.
Reaction is neutral or mildly alkaline.
The Btky horizon, when present, has the same color and textural range as the Bt horizon. Pedogenetic accumulations of carbonates and gypsum occur as soft masses, filaments, and nests of crystals, respectively. Reaction is typically mildly or moderately alkaline, but some pedons may be strongly alkaline when not buffered by excess gypsum. Texture is loam or clay loam with 18 to 30 percent clay. Pedogenetic accumulations of carbonates and gypsum occur as common soft masses, filaments, and as nests of crystals.
