, <br /> , annual temperature is about 48 degrees F. <br /> TAXONOMIC CLASS: Fine-loamy, mixed, superactive, mesic Cumulic Endoaquolls <br /> rTYPICAL PEDON: Glencoe clay loam with a concave slope of less than 1 percent in a <br /> depression on a ground moraine in cultivated field. (Colors are for moist soil unless otherwise <br /> � noted.) <br /> Ap--O to 10 inches; black (N 2/0) clay loam; massive; friable; about 2 percent gravel; cloddy; <br /> neutral; abrupt smooth boundary. <br /> � A--10 to 24 inches; black (N 2/0) clay loam; weak tine subangular blocky structure; friable; <br /> about 2 percent gravel; neutral; clear wavy boundary. (Combined thickness of A horizon is 16 to <br /> 32 inches.) <br /> ' ABg--24 to 35 inches; very dark gray (SY 3/1) clay loam; weak fine subangular blocky strucCure; <br /> friable; few tongues of dark olive gray (5Y 3/2) and olive gray (SY 4/2); about 2 percent gravel; <br /> neutral; gradual irregular boundary. (0 to 26 inches thick) <br /> � Bg--35 to 48 inches; olive gray (SY 4/2) loam; moderate coarse subangular blocky structure; <br /> friable: few tongues of very dark gray(SY 3/1); about 5 percent gravel; common fine prominent <br /> light olive brown (2.SY 5/4) and common medium prominent strong brown (7.SYR 5/6j Fe <br /> � concentrations; neutral; gradual wavy boundary. (0 to 30 inches thick) <br /> Cg--48 to 60 inches; grayish brown (2.SY 5/2) loam; massive; friable; about 5 percent gravel; <br /> many medium distinct light olive brown (2.SY 5/4) Fe concentrations; strongly effervescent; <br /> � slightly alkaline. <br /> TYPE LOCATION: Steele County, Minnesota; about 5 miles northwest of Owatonna; 2,640 <br /> � feet south, 2,660 feet west of the northeast corner of sec. 24, T. 108 N., R. 21 W.; USCS <br /> Medford West quadrangle; lat. 44 degrees 8 minutes 46 seconds N. and long. 93 degrees 17 <br /> minutes 45 seconds W., NAD27. <br /> � RANGE IN CHARACTERISTICS: Depth to free carbonates is 30 to 60 inches or more. The <br /> Ap in a few pedons will have small amounts of free carbonates. The thickness of the mollie <br /> epipedon ranges from 24 to 80 inches. The control section averages between 22 and 35 percent <br /> � clay and from 15 to 30 percent fine sand and coarser. Rock fragments of mixed lithology <br /> comprise 0 to 5 percent of the volume of the A and B horizons and 2 to 8 percent of the C <br /> horizon. Some pedons have an 0 horizon up to 6 inches in thickness. A stratified substratum <br /> � phase is recognized with silt loam, sand, sandy loam, and loamy sand textures below 40inches. <br /> The Ap or A horizon has hue of lOYR to SY or neutral, value of 2 or 3, and chroma of 0 or ]. It <br /> is clay loam, silty clay loam, or loam with 25 to 35 percent clay. Ponded phases may have mlicky <br /> � modifiers. It is commonly neutral but ranges from slightly alkaline to slightly acid. <br /> AB horizon has colors and textures similar to the A and Bg horizons. <br /> The Bg harizon has hue of SY or 2.SY, value of 2 to 5, and chroma of 1 or 2. Dark colored <br /> 1 tongues from the A horizon range from few to common. It is loam, clay loam or silry clay loam. <br /> Near the center of some depressions, some pedons have B horizons that have a slight clay <br /> increase relative to the A horizons. It is neutral to slightly alkaline, but in some pedons the lower <br /> ipart of the B horizon is slightly alkaline with slight effervescence. The Bg horizon is absent in <br /> some pedons. <br /> � <br /> � Svoboda Ecolo�ical Resources 744 Brown Road North <br /> Project No.:2007-081-03 ]9 Ted SehulCze <br /> , <br />
