MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: St. Paul, Minnesota
SERIES ESTABLISHED: Blue Earth County, Minnesota, 1906.
REMARKS:
Particle-size control section--the zone from a depth of 25 to 100 centimeters (A1, A2, AB, Bt,
and BC horizons);
series control section--the zone from the surface to a depth of 150 centimeters (Ap, A1, A2, AB,
Bt, BC, and C horizons).
Diagnostic horizons and features recognized in this pedon include:
mollic epipedon--the zone from the surface to a depth of 89 centimeters (Ap, A1, A2, AB, and Bt
horizons);
cambic horizon-the zone from a depth of 89 to 132 centimeters (BC horizon);
udic moisture regime.
The Bt horizon does not have the 1.2 percent clay increase to meet the requirements of an argillic
horizon.
Cation-exchange class is supported by lab sample number S96IA-193-005, NSSL.
Taxonomy version--tenth edition, 2006.
A cherty silt loam phase is mapped in MLRA 105, this soil is considered a fine-loamy taxadjunct
