These iron masses become larger and less bright with depth. Reaction is neutral through moderately alkaline. The C horizon has hue of 10YR or 2.5Y, value of 5 through 7 and 4 through 6 moist, with chroma of 2 through 4. It is dominantly silt loam but ranges to include clay loam, loam and silty clay loam. In some pedons, calcium carbonates are in the form of concretions or mycelial-like filaments and coatings on cleavage planes.
Reaction is neutral through moderately alkaline.
These are the Barbert , Crestmeade , Edina , Filbert , Fillmore , Massie and Triplett series. Barbert soils have soil temperatures at a depth of 20 inches that average 45 to 50 degrees F. Crestmeade and Triplett soils are in a warmer and wetter climate and do not pond water on the surface. Also, Triplett soils have more than 10 percent sand in the lower part of the particle size control section. Edina soils have a thinner solum and are more acid in the lower part or the solum. Fillmore soils pond water for brief durations during the growing season.
