, <br /> ' RANGE IN CHARACTERISTICS: Depth to free carbonates range from 30 to 65 inches. The <br /> mollic epipedon thickness ranges from 24 to 60 inches. Typically the upper colluvim contains <br /> � less than 2 percent gravel by volume and the lower part contains 2 to 6 percent gravel by volume <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 <br /> it is loam or clay loam, but silt loam or silty clay loam are within the range. It has coatings of <br /> clean sand and silt particles in the lower part of the A horizon in some pedons. It is moderately <br /> � acid to neutral. <br /> The Btg horizon has hue of lOYR, 2.SY, 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 /�I��acla, B�II�L�V, Bcr��illc, Bc��oksl��n, Buntin�,��illc, <br /> Clarl�ani�i�, C��rcl�>��a, f��>rrstritv, J�in�e�t��n, Maren�c�, Mill�ro��e, Na��an, Nc����ni, Renstiel�ier, and <br /> � W�stlan�i soils. The Alvada series (Tentative - OH) is not in the OSD file at this time. The Barry, <br /> Berville, Brookston, Cordova, Marengo, Millgrove, Navan, Rensselaer, and Westland soils have <br /> a mollic 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 Forestcity soils have 45 to 65 percent sand and 10 to 18 percent clay in the underlying <br /> � material. The J�in�est�����n 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 �den and Lester <br /> soils. These soils are well drained and are on the higher lying, gently sloping to very steep <br /> ' 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 2.5 feet for the somewhat <br /> poorly drained phase during spring in normal years. <br /> ' <br /> � <br /> ' <br />
