RANGE IN CHAI2ACT�RISTICS: Depth to free carbonates ran�e from 30 to 65
<br /> inches. The moflic epipedon thickness ranges fcom 2�4 to 60 inches. Typically the upper
<br /> colluvirn contains less tl�an 2 percent gravel by vofume and the iower pa��t contains 2 to 6
<br /> percent gravel by vo(ume of mised lithology.
<br /> The A horizons have hue of t OYR or is neutral, value of 2 or 3, and chroma of 0 to 2.
<br /> Typically it is loam or clay loam, but silt loam or silty clay laam are within the range. It
<br /> l�as coatinos of clean sand and silt particles in the lower part of the A horizon in some
<br /> pedons. It is moderately acid to neutral.
<br /> The Btg horizon has hu� of I OYR, 2.SY, or SY, value of 2 to�, and chroma of I or 2. [t is
<br /> clay loam, si(ty�clay loam high in sand, �r loam. It has between 2� and 3� percent clay '
<br /> and I S to 35 percent fine sand and coarser. It has B/A clay ratios of 1.2 to l.4. [t has fe�v
<br /> to many, faint to prominent clay filn�s. It is moderately acid to neutral. I
<br /> The C horiaon has hue of a 2.SY or SY, value of� to 6, chroma of I or 2. It is loam or i�
<br /> clay loam. It is slibhtly alkaline or moderately alkaline. The clay content ranges from I 8 '
<br /> to 32 percent and the total sand content ranges from 2� to 4� percent. '

<br /> Navan, Rensselaer, and Westland soils have a molfic epipedon that is less ttlan 24 inches I
<br /> tk�ick. The Buntingville soils have carbonates at depths of less than 20 inches. The
<br /> Clackamas and Nosoni soils (ack free carbonates in the series control section. �
<br /> The Forestcity soils have 4� to 65 percent sand and 10 to 18 percent clay in the II
<br /> underlying material, Tlle J_ii��e�tt�l�n soiis formed in a firm and very firm till associated i
<br /> �vith the Iowan Erosional surface. i
<br /> GEOGRAPHIC S�TTING: Hamel soi{s have concave slopes in swales, rims of c�osed �
<br /> depressions, foot and toe slopes, and upper drainage�vays below sloping to very steep !
<br /> slopes. Slope gradients are 1 to 4 percent. Hamel soils formed in slope colluvium and �
<br /> glacial till of Late Wisconsinan Age. IVlean annual air temperature is about d� to 48 ',
<br /> degrees F. Mean annual precipitation is about 2� to 30 inck�es. Frost free days range from �I
<br /> 125 to 165. Elevation above sea level ranges fram 700 to 1600 Feet. I
<br /> G�OGRAPHIC�+�I,LY ASSOCIATCD SOILS: These ace pcincipally t��e I la�de�� a►1d ���
<br /> f_��5t�� soils. These soils are well drained and are on the hieher lyin�, gently sloping to �
<br /> very steep slopes. j
<br /> DRAINAGE AND PCRM�ABILITY: Poorly drained and somewhat poorly drained. �I
<br /> Surface rtuloff is low or moderately low. Permeability is moderately slaw. The apparent
<br /> seasonal high water table is at .5 to 1.5 feet foi•the poorly drained phase and l.S to 2.5 j
<br /> feet for the somewhat poorly drained phase during spring in normal years. ',
<br /> USE AND V�CETATION: Nlost of this soil is cropped to corn, hay, soybeans, and
<br /> small grains. Ho�vever, significant areas are in pasture and forest. Native vegetation is
<br /> mised wet prairie grasses and deciduous forest. �
