<br /> �� feet north of the southwest corner of sec. l, T. 110 N., R. 21 W.
<br /> RANGE IN CHARACTERISTICS: Solum thickness and depth to free carbonates range from 24 to 54 �
<br /> inches. Coarse fragments of mixed lithology comprise 2 to 8 percent of the volume of the control �
<br /> section. . �
<br /> I � � . �
<br /> The A horizon has hue of lOYR,value of•2 or 3, and chroma of 1 or 2. The Ap horizon has value of 4 or �
<br /> � 5 and chroma of 1 or 2 and value of 6 when dry. The E horizon lias hue of 1 OYR, value of 4 or 5, and .
<br /> chroma of 1 or 2. The A and E horizons typically are loam, silt loam, sandy loam, or fine sandy loam,
<br /> : buf include clay loam, if eroded. They are neutral to medium acid. �
<br /> The Bt horizon has hue of lOYR in the upper part and lOYR or 2.SY in the lower part, value of 4 or 5, � .
<br /> � and chroma of 3 through 5. Mottles are present in�the lower subhorizons in some pedons. It typically.is.
<br /> � clay loam or loam,but sandy clay loam is in parts in some pedons. The argillic horizon has �18 to 35
<br /> � � percent clay a.nd 30 to 45 percent sand. It is slightly acid to strongly acid. Some pedons have a BC
<br /> , horizon. � � � .
<br /> � The C horizon has a hue of lOYR or 2.SY,value of 4 or 5, and chroma of 3 through 6. It is loam or clay
<br /> loaxn. It lacks mottles in some pedons. It has 15 to 25 percent calcium carbonate equivalent and is mildly �
<br /> or mo.derately alkalikne. . . �� .

<br /> � horizon soils have more illite in the B and C horizon; Belmont soils have redder hue in the B horizon.
<br /> Belmore, Chili,Kalamazoo, and Ockley soils formed in glacial outwash and have sandy or sandy- � .
<br /> skeletal2C horizons. Chenault soils have chert fragments in tlie solum ancl are underlaid by limestone
<br /> bedrock. Coggon, Gallman, Hickory,Pecatonica, Renova,Riddles, Summitville, and Westville�soils
<br /> , have thicker sola. In addition, Coggon soils have low chroma mottles ui part of the B2 horizon. � �
<br /> Conestoga, Kendallville,Letort, Richland, and Rockbridge soils.have more coarse fragments: Douds, El .
<br /> Dara,Kidder, Sisson, and Wawasee soils have less clay and more sand or silt in the lower�part of�the B
<br /> hori�on and in the C horizon. High Gap, Hollinger,Mandeville,Mifflin,Military,Norden,'Roseville, �.
<br /> Whalan, and Woodbine soils have bedrock beginning between depths of 20 and 60 inches. Grellton, .
<br /> Hebron;Lindley, and Rawson soils have more silt or clay or both in either the lower part of the B . �
<br /> horizon or C horizon or both. Kanawha soils are formed in alluvium from acid shale and are in an area
<br /> of higher rainfall: LeRoy and Strawn soils have thinner sola. McHenry and Miami soils have.more silt or
<br /> . � clay, or both in the upper part of the�solum. Martinsville soils have redder hue in the B horizon and
<br /> , formed in stratified outwash or lacustrine sediments. Nodine sails have thicker sola which is more
<br /> stratified and leached of free carbonates to greater depths. Owosso soils have more sand and less silt or
<br /> � clay in the upper part of their sola. Princeton soils formed in aeolian sediments and have stxatified C
<br /> � horizons. Relay soils have hue of 2.SY or SY in all parts of the B horizon. Teanaway soils have firm
<br /> sandy clay loam C horizons with redder hue. Theresa soils formed partly in loess and have 2C horizons
<br /> �with 40,to 60 percenf calcium carbonate. . � �
<br /> . GEOGRAPHIC SETTING: Hayden soils have plane or convex slopes on gently undulating through .
<br /> � : steep glacial moraines of�he Des Moines and Crrantsburg sublobe of the Late Wisconsinan glaciation.
<br /> Their slopes range from 2 to 40 percerit and mostly aze 80 to 300 feet in length. These soils formed in
<br /> calcareous loamy glacial till. Montmorillonite is the dominant clay mineral in the glacial till. Mean .
