KLOSSNER SERIES The Klossner series consists of very deep,very poorly drained soils formed in well decomposed organic material 16 to 50 inches thick overlying loamy deposits on moraines,till plains,lake plains,flood plains, and hillside seep areas.They have moderately slow to moderately rapid permeability in the organic material,and moderate or moderately slow permeability in the loamy material.Slopes range from 0 to 8 percent.Mean annual precipitation is about 28 inches.Mean annual temperature is about 47 degrees F. TAXONOMIC CLASS: Loamy,mixed, euic, mesic Terric Haplosaprists TYPICAL PEDON: Klossner muck-with a 1 percent slope in a cultivated field. (Colors are for moist soil unless otherwise stated.) Oap--O to 10 inches;black(N 2/0)muck,very dark gray(IOYR 3/1)dry; about 20 percent fiber, less than 5 percent rubbed;weak fine subangular blocky structure;very friable;many very fine roots; moderately acid; abrupt smooth boundary. Oa--10 to 26 inches;black(10YR 2/1)muck, dark gray(1 OYR 4/1)dry; about 60 percent fiber, about 6 percent rubbed; weak fine subangular blocky structure;very friable;many very fine roots; moderately acid; gradual smooth boundary. (Combined thickness of O horizon is 16 to 50 inches.) 2A1--26 to 36 inches;black(N 2/0)mucky silty clay loam; weak medium subangular blocky structure; friable; few very fine roots; slightly acid; gradual smooth boundary. 2A2--36 to 48 inches;black(N 2/0) silty clay loam; massive; friable; few dark reddish brown(5YR 3/4)iron oxide concentrations in root channels; about 1 percent gravel; neutral; gradual wavy boundary. (Combined thickness of 2A horizon is 8 to 45 inches thick.) 2Cg1--48 to 65 inches; olive gray(5Y 5/2) clay loam;massive; friable; dark reddish brown(5YR 3/4)Fe oxide concentrations in root channels;many medium prominent yellowish brown(1 OYR 5/6)Fe concentrations; about 1 percent gravel; slightly effervescent; slightly alkaline; gradual wavy bounday. 2Cg2--65 to 80 inches; gray(5Y 5/1)loam;massive; friable;many medium prominent light olive brown(2.5Y 5/4) and yellowish brown(IOYR 5/4)Fe concentrations; about 3 percent gravel; slightly effervescent; slightly alkaline. TYPE LOCATION:Nicollet County,Minnesota; 2600 feet north and 2300 feet east of the southwest comer, sec. 12,T. 110 N.,R. 28 W.;USGS Nicollet quadrangle; lat. 44 degrees 20 minutes 53 seconds N. and long. 94 degrees 8 minutes 28 seconds W., NAD27. RANGE IN CHARACTERISTICS: The thickness of the organic material ranges from 16 to 50 inches. It is derived primarily from herbaceous plants. The organic matter content ranges from 25 to 60 percent in the organic surface and 5 to 20 percent in the 2A horizon. The reaction of the organic material ranges from moderately acid to slightly alkaline. Some organic layers contain free carbonates.
