The <br />\horizon is medium acid to neutral.

Be- <br />30Se water is removed slowly by tile drains, tiles <br />I med to be closely spaced to be effective. If prop- <br />■Tly drained and managed, this soil is moderately <br />..II suited to crops grown in the county. An occa-^ <br />:ional sod crop helps tile drains to remove excess <br />•uer more rapidly. (Capability unit IIw-:; wood ­ <br />land group 6; building site group 11] <br />Shorewood Series <br />The Shorewood series consists of deep, moderately <br />^11 drained soils that formed in calcareous clayey <br />:tdiments 2 to 5 feet thick over calcareous loamy <br />till. In many places a 1-foot to 3-foot layer of <br />iilty sediment occurs between the clay and the loamy <br />till. These are nearly level to gently sloping <br />*eils in smooth, convex positions on hills and <br />njolis. Slopes are mostly simple. The native <br />^netation was mixed hardwoods. Shorewood soils are <br />*>3eciated mainly with Hayden and Erin soils. <br />In a representative profile, the surface layer is <br />black silty clay loam about 10 inches thick. The <br />^soil is about 23 inches thick and consists of <br />^ree layers. The upper part is very dark grayish - <br />silty clay; the middle part is olive-brown <br />'ilty clay, and the lower part is light olive-brown <br />^'Ity clay. The underlying material is light olive- <br />btoun clay loam. <br />Shorewood soils have high available .moisture ca ­pacity, moderately slow permeabilit:.', ar.d medium to slow internal drainage. The water table in the more nearly level areas is at a depth of 3 to 5 feet during wet periods. The root zone is deep, but plant roots develop slowly in the firm, clayey sub­soil. The surface layer is high in organic-matter <br />content. Shorewood soils are very fertile, but <br />crops grown on them respond well to additional <br />fertilizer. <br />Representative profile of Shorewood silty clay <br />loam, 0 to 2 percent slopes, in a cultivated field, <br />240 feet east and 320 feet north of the southwest <br />comer, SEl/4 SEl/4 SWl/4 sec. 23, T. 11^ N., R. 23 <br />Ap-0 to 10 inches, black (lOYR 2/1) silty clay <br />loam; strong, very fine, subangular blocky <br />structure; friable; neutral; clear, smooth <br />boundary . <br />B1--10 to 13 inches, very dark grayish-brown (2.SY <br />3/2) silty clay; strong, fine, subangular <br />blocky structure; firm; few pores; common, <br />patchy, grainy coatings cn ped faces; medium <br />acid; clear, smooth boundary. <br />B2t--18 to 30 indies, olive-brown C-‘SY 4/4) silty <br />clay; strong, medium, subangular blocky and <br />angular blocky structure; firm; common pores; <br />thick, moderately patchy, black and very dark <br />brown clay films on ped faces; sli^tly acid; <br />clear, smooth boundary. <br />B3t —50 to 33 inches, light olive-brown (Z.SY 5/4) <br />silty clay; moderate, coarse, subangular <br />blocky structure; firm; common pores; thin, <br />pateny, black clay films on vercical ped <br />faces; few black organic stains; neutral, <br />clear, smooth boundary. <br />C—33 to 60 inches, light olive-brown (2.5Y 5/4) <br />clay loam; weak, fine and medium, subangular <br />blocky structure; firm; many pores; few, fine, <br />black, Old root channel fillings; common, <br />medium, prominent, yellowish-brown (lOYR 5/8) <br />iron oxide concretions; calcareous; moderately <br />alkaline. <br />The solum is 23 to 40 inches thick. The A hori ­ <br />zon is black, very dark brown, or very dark gray. <br />The B2 horizon ranges from dark grayish brown to <br />light olivb brown auid yellowish brown in color. Tex­ <br />ture ib t>’pically silty clay that is 40 to 50 per­ <br />cent clay, but clay content ranges from 35 to 60 <br />percent. Sand content is less than 15 percent and <br />centers around 5 percent. The C horizon is grayish <br />brown to light olive brown. Te.xture is silt.: clay, <br />silty clay loam, clay loam, silt loam, zr loam, <br />depending upon thickness of the sediments. There is <br />commonly loamy till within a depth of 7 feet. The A <br />horizon is slightly acid to neutral, and the B hori ­ <br />zon is neutral to medium acid. <br />Shorewood soils are lower in sand content and <br />typically higher in clay content than similar Kil­ <br />kenny, Le Sueur, and Lerdal soils. They have a <br />thicker and darker colored A horizon than the asso ­ <br />ciated Dalbo soils . They are better drained than <br />the associated Minnetonka soils. <br />V-m: <br />•.i '. ^ vV. <br />1 ^ =:--i
