<br /> Coland and Comfrey soils do not have rock fragments in their control sections. In
<br /> addition, Coland soils are deeper to fi•ee carbonates. Defft soils are poorly drained, are not ,
<br /> in closed depressions, have prismatic structure in subsoil, and do not have tongues of the !
<br /> A horizon in the Bg horizon. Gielo�v,James Canyon, Keddie, Kimmer(ing, Konner, (
<br /> NtcClave, Peoh, and Wenas soils are drier in the soil moisture control section during the ;
<br /> 120 days fo[lowinb the summer solstice. Romnell soils contain appreciable amounts af j
<br /> gypsum in their sola. Shandep soils do not�iave tongues of A horizon in the Bg horizon �
<br /> and have a coarse teYtured 2C horizon.
<br /> G�OGRAPHIC SETTING: Glencoe soils typically are in closed depressions or low I
<br /> gradient s�vales within the Des vloines lobe of the Late Wisconsinan glaciation. The i
<br /> Glencoe soils are formed in loamy colluvial sediments and loamy glacial till. Ntean
<br /> annual temperatuee ranbes fi•om �45 to �2 degrees F. Mea� annual precipitation ranges
<br /> From 25 to 32 inches. The fi�ost £ree days range from 12=� to 172. The elevation above sea ;
<br /> level range from 700 to 1600 Feet. �

<br /> Some�vhat poorly drained Nicollet and the poorly drained Canisteo, Webster, and Harps !
<br /> soils are on nearly level to ge��tly undulating slopes. All the above have mollic epipedons
<br /> less than 24 inches thick. In addition, the Canisteo and Hac•ps soils contain fi•ee
<br /> carbonates throughout. The Glencoe soils atso are associated with the f I���cl�n and l,��t�r
<br /> soils and their respective topograpfiic associates in some places. �
<br /> DRAINAGE AND PCRNIEABILITY: Very poorly drained. 5urface runoff is '
<br /> negligible. Permeability is moderate or moderately slo�v. ,
<br /> USE AND VEG�TATION: Mostty drained and cropped to corn and soybe�ns. Native
<br /> vegetation was a wet site plant community of the tall grass prairie plant formation. �'
