TYPE LOCATION: Roseau County. Minnesota; about 4 miles southwest of Badger; 2,500 feet south and 250 feet east of the northwest corner of section 29, T. 161 N., R. 42 W.; 48 degrees, 44 minutes, 22 seconds north latitude and 96 degrees, 6 minutes, 58 seconds west longitude; USGS Greenbush NE topoquadrangle.
RANGE IN CHARACTERISTICS: Thickness of the mollic epipedon ranges from 7 to 16 inches. The depth to the 3C horizon ranges from 20 to 40 inches.
The A horizon has hue of 10YR or 2.5Y or is neutral, value of 2 or 3, and chroma of 0 to 2. Texture is loam, fine sandy loam or sandy loam. Reaction is slightly alkaline or moderately alkaline. Some pedons have an Ak horizon.
The Bk horizon has hue of 2.5Y or 5Y, value of 4 to 6, and chroma of 1 or 2 or is neutral. Textures are similar to the A horizon. The Bk is absent in some pedons that have an Ak horizon.
Some pedons have a 2Bk or 3Bk horizon.
The 2C horizon has hue of 2.5Y or 5Y or is neutral, value of 4 to 6, and chroma of 0 to 2. It averages 35 to 75 percent rock fragments. Distinct or prominent redoximorphic features commonly are present. The fine-earth fraction is coarse sand, sand or loamy sand. Reaction is slightly alkaline or moderately alkaline.
The 3C horizon has hue of 2.5Y or 5Y, value of 4 to 6, and chroma of 1 or 2. It has less than 15 percent rock fragments. Commonly distinct or prominent redoximorphic features are present. Reaction is slightly alkaline or moderately alkaline. Gypsum crystals may be present in the 2C and 3C horizons.
The 3C horizon in the Percy till phase has textures of sandy loam, fine sandy loam, loam or silt loam. It has 12 to 18 percent clay and more than 15 percent fine sand and coarser sand. Calcium carbonate equivalent ranges from 20 to 40 percent. Moist bulk density ranges from 1.75 to 2.00 g/cc.
The 3C horizon in the Des Moines till phase has textures of loam, clay loam or silty clay loam. It has 18 to 35 percent clay and more than 15 percent fine sand and coarser sand. Calcium carbonate equivalent ranges from 10 to 25 percent. Moist bulk density ranges from 1.35 to 1.60 g/cc.
COMPETING SERIES: There are no other series in this family.
GEOGRAPHIC SETTING: Mavie soils formed in a mantle of loamy over very gravelly sandy glaciolacustrine sediments overlying loamy till. These materials are of the late Wisconsin Age. Typically these soils occur on slightly concave broad flats adjacent to beach ridges. Slope ranges from 0 to 2 percent. Mean annual air temperature ranges from 37 to 45 degrees F. Mean annual precipitation ranges from 19 to 24 inches. Frost-free days range from 110 to 135. Elevation above sea level ranges from 750 to 1250 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Foxhome, Rockwell, Roliss, Strathcona, Syrene, Strandquist and Vallers soils. Foxhome soils have a wet soil moisture status at depths of 2.5 to 5 feet at some time during the period of April through June and are higher lying. Rockwell, Roliss, Strathcona, Syrene and Strandquist soils are on similar positions and Vallers soils are on slightly convex areas. Rockwell and Strathcona soils do not have very gravelly 2C horizons. Roliss and Vallers soils are loamy throughout. Syrene soils do not have loamy 3C horizons. Strandquist soils do not have calcic horizons.
DRAINAGE AND PERMEABILITY: Poorly drained. Runoff is negligible. Permeability is rapid in the upper layers and moderate or moderately slow in the underlying material. The soil has a wet soil moisture status at depths as high as 0.5 to 1.5 feet at some time from April through July in most years.
USE AND VEGETATION: Commonly used to grow small grains, sunflowers, and hay. Some areas are pastured. Native vegetation is tall grass prairie with scattered areas of aspen.
DISTRIBUTION AND EXTENT: The Mavie series occurs primarily in eastern and east central portions of the glacial Lake Agassiz basin in northwestern Minnesota. It is moderate in extent.

REMARKS: Diagnostic horizons and features recognized in this pedon are: mollic epipedon - the zone from the surface of the soil to a depth of 12 inches (Ap horizon); calcic horizon - the zone from 12 to 18 inches (Bkg horizon); aquic moisture regime per low chroma with redoximorphic features below the Ap horizon.
