MUSKEGO SERIES <br /> The Muskego series consists of very deep,very poorly drained soils formed in herbaceous organic material <br /> over coprogenous limnic material(sedimentary peat)on glacial lake plains and flood plains.T'hese soils <br /> have moderate or moderately rapid <br /> permeability in the herbaceous organic material and slow permeability in the coprogenous material. Slopes <br /> range from 0 to 2 percent.Mean annual precipitation is about 30 inches near the typical pedon site.Mean <br /> annual temperature is about 49 degrees <br /> F. <br /> TAXONOMIC CLASS: Coprogenous, euic,mesic Limnic Haplosaprists <br /> TYPICAL PEDON: Muskego muck- on a slope of less than 1 percent in a cultivated <br /> field at an elevation of about 815 feet. (Colors are for moist soil unless otherwise stated.) <br /> Oap--O to 9 inches;black(lOYR 2/1)broken face and rubbed muck(sapric material); <br /> about 25 percent fiber, 4 percent rubbed;moderate very thick platy structure parting to <br /> moderate fine subangular blocky; friable;many fine roots; mostly herbaceous fiber; <br /> neutral; abrupt smooth boundary. <br /> Oal--9 to 14 inches;black(lOYR 2/1)broken face muck(sapric material); about 30 <br /> percent fiber, 5 percent rubbed;moderate very thick platy structure parting to moderate <br /> fine subangular blocky; friable; many fine roots; mostly herbaceous fiber; neutral; abrupt <br /> smooth boundary. <br /> Oa2--14 to 30 inches; dark brown(7.SYR 3/2)broken face muck(sapric material)with <br /> few thin(less than 1 inch) layers of mucky peat (hemic material); about 50 percent fiber, <br /> 7 percent rubbed; weak thin platy structure; few fine roots; slightly acid; gradual smooth <br /> boundary. <br /> Lcol--30 to 48 inches; dark olive gray(SY 3/2) coprogenous material with fine thin(less <br /> than 1 inch) lenses of yellowish brown(lOYR 5/6)mucky peat(hemic material); weak <br /> very thin platy structure; slightly plastic; neutral; diffuse smooth boundary. , <br /> Lco2--48 to 60 inches; very dark grayish brown(2.SY 3/2) coprogenous material; <br /> massive; slightly plastic; slightly alkaline. <br /> TYPE LOCATION: Ozaukee County, Wisconsin; about 1 mile east and 2 1/2 miles <br /> south of Fredonia; 2,500 feet north and 500 feet west of the southeast corner of sec. 11, <br /> T. 11 N., R. 21 E. or 350 feet north and 375 feet west of end of farmstead driveway; <br /> USGS Fort Washington topographic quadrangle; latitude -43 degrees, 25 minutes, 58 <br /> seconds N. and longitude - 37 degrees, 56 minutes, 34 seconds W. NAD 27. <br /> RANGE IN CHARACTERISTICS: Thickness of the herbaceous organic layers and <br /> depth to coprogenous material (sedimentary peat)ranges from 16 to 51 inches. Fibers are <br /> derived primarily from herbaceous plants. Some pedons contain fragments of twigs, <br /> branches, or logs that range from 1/8 to 5 inches in diameter and amount to less than 15 <br /> percent of the volume. Reaction ranges from strongly acid to neutral (water, 1:1) in the <br /> surface tier and from strongly acid to slightly alkaline(water, 1:1)in the subsurface and <br />
