Vallers soil series
The Vallers series consists of very deep, poorly drained soils that formed in calcareous fine-loamy till on till plains, moraines and lake plains. These soils have moderately slow permeability. Slopes range from 0 to 3 percent.
TAXONOMIC CLASS: Fine-loamy, mixed, superactive, frigid Typic Calciaquolls
The mollic epipedon ranges from 7 to 25 inches in thickness. In some pedons the lower part of the mollic epipedon qualifies as part of the calcic horizon. The calcic horizon has a calcium carbonate equivalent of about 20 to 35 percent. The 10 to 40 inch particle-size control section typically has between 22 and 32 percent clay but ranges from 18 to 35 percent and 15 to 35 percent sand coarser than very fine sand. It typically contains 2 to 8 percent rock fragments of mixed lithology, but in some pedons the upper part lacks rock fragments. Typically, the soil is calcareous throughout, but a few pedons under native vegetation lack free carbonates in the upper 7 inches of the soil. The soil is typically slightly alkaline or moderately alkaline throughout, but is neutral in the surface layer where it lacks free carbonates. Firm subsoil, saline, stony, and depressional phases are recognized.
USE AND VEGETATION: Most of this soil is cultivated. Corn, soybeans, small grains and legumes are the principal crops. Native vegetation is tall grass prairie.
DISTRIBUTION AND EXTENT: Western Minnesota, northeastern South Dakota, and eastern North Dakota. The series is of large extent.
Diagnostic horizons and features recognized in this pedon are: mollic epipedon - the zone from the surface to a depth of 9 inches (Ap horizon); calcic horizon - the zone from 9 to 44 inches (Bkg and Bkyg horizons); aquic moisture regime per 5Y hue, chroma of 2 and redoximorphic concentrations below the mollic epipedon.
