(0 to 7 inches thick)
Bw1--10 to 19 inches; dark yellowish brown (10YR 4/4) fine sandy loam with a few thin strata of fine sand; weak medium subangular blocky structure; very friable; breaks to weak thin plates along depositional strata; common very fine and fine roots; very strongly acid; clear smooth boundary.
Bw2--19 to 29 inches; dark yellowish brown (10YR 4/4) fine sandy loam with common thin strata of fine and very fine sand; weak coarse subangular blocky structure; friable; breaks to moderate medium plates along depositional strata; few very fine and fine roots; few fine prominent strong brown (7.5YR 4/6) masses of iron accumulation; very strongly acid; clear smooth boundary.
Bw3--29 to 39 inches; dark yellowish brown (10YR 4/4) fine sandy loam with few thin strata of fine sand; weak coarse subangular blocky structure; friable; breaks to moderate medium plates along depositional strata; few very fine and fine roots; common medium prominent strong brown (7.5YR 5/6) masses of iron accumulation; very strongly acid; clear smooth boundary. (Combined thickness of the Bw horizons ranges from 8 to 35 inches.)
2C--39 to 60 inches; dark yellowish brown (10YR 4/6) gravelly sand; single grain; loose; few medium faint yellowish brown (10YR 5/6) masses of iron accumulation; about 20 percent gravel; strongly acid.
TYPE LOCATION: Barron County, Wisconsin; about 3 miles south of Cumberland; 2200 feet south and 1850 feet east of the northwest corner of sec. 32, T. 35 N, R. 13 W.
RANGE IN CHARACTERISTICS: Thickness of the solum, thickness of the loamy mantle, and depth to sandy alluvium all range from 24 to 40 inches. Organic matter content shows an irregular decrease with depth. Rock fragments typically are absent in the loamy mantle. Volume of gravel ranges from 0 to 35 percent in the sandy alluvium. Reaction ranges from extremely acid to slightly acid to a depth of 30 inches and from extremely acid to neutral below 30 inches. Redox accumulations are within a depth of 40 inches. Saturation occurs at 30 to 40 inches at some time in most years.
The A horizon has hue of 10YR, 7.5YR, or 5YR; value of 3 or 4; and chroma of 1 to 3.
The E horizon has hue of 5YR, 7.5YR, or 10YR; value of 4 to 6; and chroma of 2 or 3. It is fine sandy loam, sandy loam, loam, very fine sandy loam, or silt loam. Typically it has thin strata of coarser or finer texture.
The Bw horizon has hue of 5YR, 7.5YR, or 10YR; value of 3 to 6; and chroma of 4 to 6. It is fine sandy loam, sandy loam, loam, very fine sandy loam, or silt loam. Typically it has thin strata of coarser or finer texture. Organic carbon content ranges from .3 to .6 percent.
Some pedons have a 2BC horizon with hue of 7.5YR or 10YR, value of 4 to 6, and chroma of 3 to 6. It is sand, fine sand, loamy sand, loamy fine sand, or the gravelly analogs or is startified with these textures. Some pedons have thin strata of finer texture.
The 2C horizon has hue off 7.5YR or 10YR, value of 3 to 6, and chroma of 2 to 6. Value of 3 and chroma of 2 or 3 do not occur together. The 2C horizon has texture like the 2BC horizon.
COMPETING SERIES: There are no competing series. Similar soils are the Kickapoo and Moquah series. Kickapoo soils do not have a cambic horizon and are mesic. Moquah soils do not have a cambic horizon.
GEOGRAPHIC SETTING: Moppet soils are on flood plains. The topography is nearly level or gently undulating with slope gradients from 0 to 3 percent. The soils formed in loamy alluvium. Mean annual precipitation ranges from 28 to 33 inches. Mean annual temperature ranges from 39 to 45 degrees F. The frost free period ranges from about 120 to 135 days. Elevation ranges from 800 to 1950 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: This is the Fordum series. The poorly drained Fordum soils are in lower positions on the flood plain.
DRAINAGE AND PERMEABILITY: Moderately well drained. Surface runoff is slow. Permeability is moderate or moderately rapid in the loamy alluvium and rapid in the sandy alluvium. These soils have an apparent seasonal high water table at a depth of 2.5 to 3.5 feet for 1 month or more per year at some time during the period September to June in 6 or more out of 10 years. These soils are subject to occasional very brief flooding mostly from September to June.
USE AND VEGETATION: Many areas are in woodland. Native vegetation is mixed hardwoods and a few conifers. Common trees are red maple, northern red oak, American basswood, white ash, silver maple, white spruce, and eastern white pine. Some areas have a cover of grasses and weeds. Some areas are used for pastureland.
DISTRIBUTION AND EXTENT: Northern Wisconsin. This soil is of small extent.
