<br /> of mixed lithology.
<br /> ' The A horizons have hue of lOYR or is neutral, value of 2 or 3, and chroma of 0 to 2. Typically it
<br /> is loam or clay loam, but silt loam or silty clay loam are within the range. It has coatings of clean
<br /> � sand and silt particles in the lower part of the A horizon in some pedons. It is moderately acid to
<br /> neutral.
<br /> The Btg horizon has hue of lOYR, 2SY, or SY, value of 2 to 4, and chroma of 1 or 2. It is clay
<br /> � loam, silty clay loam high in sand, or loam. It has between 25 and 35 percent clay and 15 to 35
<br /> percent fine sand and coarser. It has B/A clay ratios of 1.2 to 1.4. It has few to many, faint to
<br /> prominent clay films. It is moderately acid to neutral.
<br /> � The C horizon has hue of a 2.SY or SY, value of 4 to 6, chroma of 1 or 2. It is loam or clay loam.
<br /> It is slightly alkaline or moderately alkaline. The clay content ranges from 18 to 32 percent and
<br /> the total sand content ranges from 25 to 45 percent.
<br /> � COMPETING SERIES: These are the Alvada, �3arry, Berville, Brookston, Buntingville,
<br /> Clackama�, C�>r�i��va, I���restcity, Jameston, Maren��o, Mill�rove, Navan, Nosoni, Rcnssclaer, and
<br /> Westland soils. The Alvada series (Tentative - OH) is not in the OSD file at this time. The Barry,
<br /> � Berville, Brookston, Cardova, Marengo, Millgrove, Navan, Rensselaer, and Westland soils have
<br /> a mollie epipedon that is less than 24 inches thick. The Buntingville soils have carbonates at
<br /> depths of less than 20 inches. The Clackamas and Nosoni soils lack free carbonates in the series
<br /> � control section.
<br /> The Forestciry soils have 45 to 65 percent sand and ]0 to 18 percent clay in the underlying
<br /> materiaL The Jamcstc�wn soils formed in a firm and very firm till associated with the Iowan
<br /> , Erosional surface.
<br /> GEOGRAPHIC SETTING: Hamel soils have concave slopes in swales, rims of closed
<br /> depressions, foot and toe slopes, and upper drainageways below sloping to very steep slopes.
<br /> � Slope gradients are 1 to 4 percent. Hamel soils formed in slope colluvium and glacial till of Late
<br /> Wisconsinan Age. Mean annual air temperature is about 45 to 48 degrees F. Mean annual
<br /> � precipitation is about 25 to 30 inches. Frost free days range from 125 to 165. Elevation above sea
<br /> level ranges from 700 to 1600 feet.
<br /> GEOGRAPHICALLY ASSOCIATED SOILS: These are principally the Ha dcn and I,cster
<br /> � soils. These soils are well drained and are on the higher lying, gently sloping to very steep slopes.
<br /> DRAINAGE AND PERMEABILITY: Poorly drained and somewhat poorly drained. Surface
<br /> runoff is low or moderately low. Permeability is moderately slow. The apparent seasonal high
<br /> � water table is at .5 to 1.5 feet for the poorly drained phase and 1.5 to 2S feet for the somewhat
<br /> poorly drained phase during spring in normal years.
<br /> USE AND VEGETATION: Most of this soil is cropped to corn, hay, soybeans, and small
<br /> � grains. However, significant areas are in pasture and forest. Native vegetation is mixed wet
<br /> prairie grasses and deciduous forest.
<br /> DISTRIBUTION AND EXTENT: Primarily in the southeast one-quarter of Minnesota in the
<br /> 1 timbered, hilly, "gray" till region. Moderately extensive.
<br /> MLRA OFFICE RESPONSIBLE: St. Paul, Minnesota
<br /> ISERIES ESTABLISHED: Hennepin County, Minnesota, 1969.
