'; The A or Ap horizons have hue of lOYR, value of 2 or 3, and chroma of I or 2. The E
<br /> . horizon where present, has value of 3 to 5, and chroma of 1 to 3. The A and E horizons
<br /> are loam or clay loam, but sandy loam, fine sandy loam, or sil[ loam is within the range.
<br /> They range from moderately acid to neutraf.
<br /> The Bt horizon has hue of IOYR or 2.SY, value of 4 or 5, and chroma of 3 or 4. It is clay
<br /> loam or loam and has 24 to 35 percent clay and 30 to 45 percent sand. The B/A clay
<br /> , ratios range from 1.2 to 1.4. It is strongly acid to slightly acid in the upper part and
<br /> moderateky acid to neutral in the [ower part. A Bw horizon is sometimes present below
<br /> the Bt.
<br /> � The Bk horizon has hue of lOYR or 2.SYR, value of 4 or 5, and chroma of 3 to 6.The Bk
<br /> . horizon is loam or clay loatn. It is slightly alkaline or moderately alkaline. Relict
<br /> redoximorphic features are present in some pedons. �
<br /> � The C horizon has hue of 2.SY oz lOYR, value of 4 to 6, and chroma of 3 to 6. It is loam
<br /> or clay loam. It is slightly alkaline or moderately alkaline. Relict redoximorphic featares
<br /> are present in some pedons. �
<br /> COMPETING SERIES: These are the Angus,Ar�,vle, Baltimore, Bassett, BIoT omin�,
<br /> Caleb, Dowa iac, Danbrid�e, Gara, Koronis,Lauramie, Lon lois, L dick, Mohawk,
<br /> . Neda, Newcomer, Oneco;Orwood,Racine,Razort, Sehbo,TaoDi,Waucoma, and
<br /> Winneshiek soiis in the same family. Angus and Sebbo soil have saturation in the lower
<br /> ' third of the series eontrol section. Argyle,Baltimore, and Oneco soils have B horizons
<br /> , . � with 7.SYR or redder hue. Bassett soils are very strongly acid to moderately acid in the
<br /> upper part of the Bt horizon.Blooming and Racine soils have 15 to 35 percent sand in the
<br /> ' upper part of the particle-size control sectian. Caleb soils have some subhorizons that
<br /> �. have more than 45 percent in the lower part of the control section. Dowagiac and Koronis �
<br /> , soils have less than 24 percent clay in the lower one third of the particle-size control
<br /> section. Dunbridge,Waucoma,Newcomer and Winneshiek soils have soIa terminated by
<br /> bedrock at depths abdve 60 inches.Gara soils average less than 2 percent rock fragments
<br /> in the control section. Longlois, Lydic, and Neda soils have more than 8 percent rock
<br /> €ragments in some subhorizon of the control section. Lauramie soils have rnare than 45
<br /> percent sand in some subhorizon in the middle part of the control seetion. Mohawk soils
<br /> have a higher content of silt and have dark color�s in the B horizon which apparently aze
<br /> inherited from dark shale. Orwood soils have no rock fragments in the particle-size
<br /> control section. Razort soils have less than 30 percent sand in the control section.
<br /> � GEOGRAPHIC SETTING:These soils have convex siopes on moraines and till plains.
<br /> Slope gradients range from 5 to 70 percent.They formed in calcareous, loamy glacial tiIl
<br /> of late Wisconsinan Age.Mean annual temperature ranges from 45 degrees Eo 52 degxees
<br /> F. Nlean annuat precipitation ranges from 25 to 33 inches. Frost free days range from 125
<br /> to 1 b5. EIevations range from 700 to 1 b00 feet.
<br /> GEOGRAPHICALLY ASSOCIATED SOILS: These include the Cordova, Dundas,
<br /> Glencoe, Hamel, Houghton, Klossner, Le Sueur,Muske�o, and Nessel soils. Poorly
<br /> , drained Cordova and somewhat poorly and poorly drained Dundas soils are on flats and
<br /> upper drainageways with a high seasonal water table. Very poorly drained Glencoe,
