TYPE LOCATION: Meeker County, Minnesota; about 4.5 miles south of the city of Dassel, 2200 feet east and 1500 feet north of the southwest corner of sec. 22, T. 118 N., R. 29 W.; USGS Dassel quadrangle, lat. 45 degrees 0 minutes 45 seconds N. and long. 94 degrees 18 minutes 30 seconds W., NAD27
RANGE IN CHARACTERISTICS: The lower one third of the series control section is saturated for at least 30 consecutive days during April to July and other periods of high rainfall during 6 years out of 10. Depth to free calcium carbonate ranges from 18 to 40 inches. Rock fragments range from 1 to 8 percent by volume throughout the profile. The mollic epipedon is 9 to 18 inches thick.
The A and Ap horizons have hue of 10YR, value of 2 or 3 and chroma of 1 or 2. The A horizon is loam or clay loam. The reaction is moderately acid to neutral.
Some pedons have an E horizon as much as 3 inches thick.
The Bt horizon has hue of 10YR or 2.5Y, value of 4 or 5 and chroma of 3 or 4. Clay films are few to common. The Bt horizon commonly is clay loam or loam, but includes subhorizons of sandy clay loam. The B/A clay ratios range from 1.2 to 1.3. It is moderately acid to neutral.
The Bk and C horizons have a hue of 10YR or 2.5Y, value of 4 to 6 and chroma of 3 or 4. They are loam or clay loam. The clay content ranges from 22 to 30 percent. The sand content ranges from 30 to 45 percent. The calcium carbonate equivalent ranges from 5 to 25 percent. The reaction is slightly alkaline or moderately alkaline.
COMPETING SERIES: These are the Atkinson, Burchard, Calmar, Cokato, Cresco, Durand, Friesland, Griswold, Hitt, Hochheim, Jasper, Joslin, Keosauqua, La Rose, Linkville, Markesan, Moingona, Morrill, Pana, Plattville, Ringwood, Rockton, Rotamer, Schoolcraft, Shelby, Sibleyville, Velma, Wea and Winnebago series. Atkinson, Calmar, Hitt, Plattville, Rockton, and Sibleyville soils have sola that is terminated by lithic or paralithic contact within 60 inches. Burchard, Cokato, Cresco, Griswold, La Rose, Linkville, Moingona, Pana, Rotamer, Schoolcraft, Shelby and Winnebago soils do not have saturation in the lower third of the series control section for more than one month. Joslin soils have a layer in the lower half of the series control section that has hue of 2.5YR or 5YR and a clay content of greater than 35 percent. Keosauqua and Wea soils have strata of sand and less than 20 percent clay in the lower third of the series control section. Friesland soils have silt loam or silty clay loam textures within the series control section. Hochheim and Markesan soils have more than 40 percent calcium carbonate equivalents in the lower third of the series control section. Jasper soils have more than 45 percent sand in the lower third of the series control section. Durand soils have less than 20 percent clay in the upper third of the series control section. Morrill and Ringwood soils have less than 35 percent sand in the upper third of the series control section. Velma soils have strongly acid or very strongly acid reaction in the upper part of the argillic horizon.
GEOGRAPHIC SETTING: Reedslake soils are on convex and linear slopes on ground moraines. They formed in calcareous, loamy glacial till of the Late Wisconsin glaciation. Slopes range from 2 to 5 percent. Mean annual air temperature ranges from 45 to 50 degrees F. Mean annual precipitation ranges from 25 to 32 inches. Frost-free days range from 125 to 165 days. Elevation above sea level ranges from 700 to 1600 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These include the Cordova, Cokato, Glencoe, Hamel, Le Sueur and Storden soils which formed in similar parent materials. The well drained Storden soils are calcareous throughout and are on shoulders and backslopes. The moderately well drained Le Sueur soils are on sideslopes and are wetter. The poorly drained Cordova soils are on nearly level positions. The well drained Cokato soils are above Reedslake soils and are drier. The poorly drained Hamel soils are on footslopes. The very poorly drained Glencoe soils are in closed depressions.
DRAINAGE AND PERMEABILITY: Well drained. Permeability is moderate. Runoff is moderately low. The apparent seasonal high water table is 3.5 to 6 feet from March to June in most years.
USE AND VEGETATION: Most areas of these soils are used for cropland. A few areas are in pasture and woodland. Native vegetation is tall grass prairie and mixed northern hardwoods.
DISTRIBUTION AND EXTENT: Central and South central Minnesota. Extensive. MLRA-103.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: St. Paul, Minnesota
SERIES ESTABLISHED: Meeker County, Minnesota, 1995.
REMARKS: Other features: Mollic epipedon - the zone from the surface to 12 inches (Ap horizon); argillic horizon - the zone from 12 to 26 inches (Bt horizon); udic moisture regime. This soil was formerly included with the Cokato series but was separated because of soil saturation in the lower part of the profile.
