SHOREWOOD SERIES <br /> T'he Shorewood series consists of very deep,moderately well drained and somewhat poorly drained soils <br /> that formed in a mantle of clayey glacial lacustrine sediments and underlying loamy calcareous till or that <br /> formed entirely in lacustrine sediments.These soils are in glacial lake plains and moraines.Permeability is <br /> moderately slow or slow. Slopes range from 0 to 12 percent.Mean annual precipitation is about 28 inches. <br /> Mean annual temperature is about 47 degrees F. <br /> TAXONOMIC CLASS: Fine, smectitic, mesic Aquertic Argiudolls <br /> TYPICAL PEDON: Shorewood silty clay loam with a slightly convex 3 percent slope in <br /> a cultivated field. (Colors are for moist soil unless otherwise noted.) <br /> Ap--O to 8 inches; black (lOYR 2/1) silty clay loam, dark gray (lOYR 4/1) dry; weak <br /> very fine and fine subangular blocky structure; friable; many roots; neutral; abrupt <br /> smooth boundary. <br /> A--8 to 11 inches; black(lOYR 2/1) silty clay loam; weak and moderate very fine and <br /> fine subangular blocky structure; friable; many roots; neutral; clear smooth boundary. <br /> (Combined thickness of A horizons is 8 to 16 inches thick) <br /> AB--11 to 17 inches; very dark gray (lOYR 3/1) grading to very dark grayish brown <br /> (lOYR 3/2) in lower part, silty clay loam, dark gray(lOYR 4/1) dry; moderate very fine <br /> and fine subangular and angular blocky structure; friable; many faint gray (lOYR 5/1) <br /> coatings of clean silt and sand on faces of peds; few roots; slightly acid; clear smooth <br /> boundary. (0 to 10 inches thick) <br /> Bt1--17 to 24 inches; dark grayish brown(lOYR 4/2) silty clay; weak and moderate fine <br /> and medium prismatic structure; firm; many faint very dark grayish brown(lOYR 3/2) <br /> clay films on faces of peds; few distinct light gray (lOYR 6/1) coatings of clean sand and <br /> silt on faces of peds; strongly acid; clear smooth boundary. <br /> Bt2--24 to 33 inches; dark grayish brown(2.SY 4/2) clay; common fine distinct olive <br /> brown(2.SY 4/4) Fe concentrations; weak and moderate medium and coarse prismatic <br /> structure; firm; many faint very dark grayish brown(2.SY 3/2) and few prominent black <br /> (lOYR 2/1) clay films on faces of peds and in root channels; strongly acid; clear smooth <br /> boundary. <br /> Btg--33 to 39 inches; grayish brown(2.SY 5/2) silty clay; common fine distinct light <br /> olive brown(2.SY 5/6) Fe concentrations; weak coarse prismatic structure parting to <br /> weak and moderate fine and very fine subangular blocky; friable; common prominent <br /> black(lOYR 2/1) clay fillings in root channels; slightly effervescent; neutral; clear <br /> smooth boundary. (Combined thickness of the Bt horizon is 18 to 38 inches) <br /> 2BCg--39 to 45 inches; grayish brown(2.SY 5/2) clay loam; common fine distinct olive <br /> brown(2.SY 4/4) and light olive brown(2.SY 5/4) Fe concentrations; weak fine <br /> subangular blocky structure; friable; few faint dark grayish brown(2.SY 4/2) and few <br /> prominent black(l 0YR 2/1) clay fillings in root channels; about 3 percent gravel; <br /> strongly effervescent; slightly alkaline; clear smooth boundary. <br /> 2Cg--45 to 60 inches; grayish brown(2.SY 5/2) loam; common fine distinct light olive <br /> brown(2.SY 5/6) Fe concentrations; massive with some horizontal cleavages; about 5 <br /> percent gravel; strongly effervescent; slightly alkaline. <br /> TYPE LOCATION: Blue Earth County, Minnesota; about 4 miles southeast of <br /> Mankato; 2300 feet east and 100 feet north of the southwest corner of sec. 34, T. 108 N., <br />
