<br />Winents do not occur in all areas, but where they
<br />«occur, they are up to 4 feet in thickness.

<br />•n»is soil needs drainage to be productive. 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 />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 />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 />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.
