REMARKS:
Particle-size control section--the zone from a depth of 30 to 80 centimeters (Bt1, 2Bt2, and 2Bt3 horizons);
series control section--the zone from the surface to a depth of 150 centimeters (Ap, BE, Bt1, 2Bt2, 2Bt3, 2Bt4, 2BC, and 2C horizons).
Diagnostic horizons and features recognized in this pedon include:
ochric epipedon--the zone from the surface to a depth of 20 centimeters (Ap horizon);
argillic horizon--the zone from a depth of 30 to 102 centimeters (Bt1, 2Bt2, 2Bt3, and 2Bt4 horizons);
udic moisture regime.
Cation-exchange activity class is inferred from lab data from similar soils in the surrounding area.
