, ' textures. It is moderatel acid t y o shghtly alkalme. Some pedons contam thm layers of ' coprogenous earth. The 2Cg horizon has hue of lOYR, 2.SY, SY, SGY, or is neutral, value of 2 to 7 and ctu-oma of 0 to 2. It is loam, silt loam, silty clay loam, clay loam, sandy clay loam, sandy loam or fine sandy ' loam, or their gravelly or cobbly analogues. It is slightly acid to moderately alkaline. The upper 30 cm(12 inches) of this horizon averages less than 35 percent clay. Some pedons contain thin strata of fine sand, loamy sand, or silt. Gravel or cobble sized rock fragments range from 0 to 25 � percent by volume. Some pedons contain free carbonates. Sandy substratum and ponded phases are recognized. A firm tilt phase of clay loam with a moist bulk density of 1.6 to 1.9,gm/cc is recognized. � COMPETING SERIES: These are Lim�oud, Me�lo. Palrns, Philbon and Shalcar series. Linwood soils have well expressed granular structure to depths of rnore than 30 cm(12 inches) and formed mainly in woody fibers. Medo soils have sandy textur�s in the lower part of the � series control section. Palms soils have organic matter content greater than 75 percent and do not have an A horizon directly below the organic material. Philbon soils have fibi�ic and hemic material in the upper 30 cm(12 inches). Shalcar soils have less thari 3 degrees C (26 degrees F) , difference between mean January and mean July temperatures. GEOGRAPHIC SETTING: Klossner soils are in basins that were formerly lakes or ponds, lake plains, till plains, flood plains, or moraines. They are also on hillside seep areas in moraines and � side slopes of river valleys. Slope ranges from 0 to 9 percent. The soiis on nearby uplands are generally loamy. The mean annual air temperature ranges from 7 to 11 degrees C (45 to 50 degrees F). The mean annual precipitation ranges from 610 to 813 mm(24 to 32 inches). Frost- ' free period ranges fi•om 110 to 160 days. Elevation above sea level ranges from 244 to 427 m (800 to 1400 feet). GEOGRAPHICALLY ASSOCIATED SOII,S: 1`he main ones are the Callisteo, I-Iai-us, , Okoboii, Glencoe, Muske�o and I-lou�hton soils. Canisteo and Harps soils are on the rims of depressions. Glencoe and Okoboji are at the outer edges of the depressions. Muskego and Houghton soils are in larger depress�ons. , DRAINAGE AND SATITRATED HYDRAULIC CONDUCTIVIT'Y: Very poorly drained. Surface runoff is negligibte to ponded. The saturated hydraulic conductivity, measured in em p� hour, is .OS to 5.1 (.02 to 2.0 inches) in the upper m�terial and .OS to 1.5 (.02 to .6 inches) in the ' lower part. Seasanal high saturation ranges frorn plus 91 to 30 crn(3 to 1 foot) for undrained areas of this soil. Areas that are drained have variable depths to saturation based on the effectiveness of the drainage network. ' USE AND VEGETATION: The greater part of this soil is cultivated to corn, soybeans, small grains and specialty crops such as vegetables or grass sod. Other areas are in vegetation of grasses, reeds, sedges, alder, aspen, or willow. Some of the hillside seep ai•eas are set aside as ' natural areas and called fens. DISTRIBUTION AND EXTENT: The south central and southeast part of Minnesota and passi`bly northern Iowa. The series is extensive. � MLRA OFFICE RESPONSIBLE: St. Paul, Minnesota SERIES ESTABLISHED: I�iicollet County, Minnesota, 1989. REMARKS: Diagnostic horizons and features recognized are: sapric soil materials from the ' surface to about 66 cm(26 inches); loamy mineral material from 66 to l27 cm(26 to SO inches) or more; aquic moisture regime.
