<br />loam, and fine sandy loam, but they are predominantly
<br />loam. Platte soils are sandy and poorly drained. Las
<br />Animas soils are poorly drained, stratified sandy loams.
<br />Typical pedon of Bankard sand, in native grass about
<br />24 miles south of Eckley on the south streambank of the
<br />Arikaree River, 425 feet west and 340 feet north of the
<br />southeast corner of sec. 25, T. 3 S., R. 46 W.
<br />A1-0 to 5 inches; light brownish gray (10YR 6/2) sand,
<br />dark grayish brown (10YR 4/2) moist; weak fine
<br />granular structure; soft, very friable; common very
<br />fine, fine, and medium roots; strongly effervescent;
<br />moderately alkaline; clear wavy boundary. •
<br />C1 -5 to 30 inches; very pale brown (10YR 7/3) sand,
<br />brown (10YR 5/3) moist; single grain; loose;
<br />common very fine, fine, and medium roots; weakly
<br />effervescent; moderately alkaline; clear wavy
<br />boundary.
<br />C2 -30 to 60 inches; very pale brown (10YR 7/3) sand,
<br />brown (10YR 5/3) moist; common medium distinct
<br />yellowish brown (10YR 5/6) mottles; single grain;
<br />loose; few fine and medium roots; weakly
<br />effervescent; moderately alkaline.
<br />Bankard soils typically are calcareous; in some
<br />pedons, they are noncalcareous in the upper few inches.
<br />The C horizon ranges from sand to mixed sand and
<br />gravel.
<br />Bayard series
<br />The Bayard series consists of deep, well drained soils
<br />that formed in calcareous, moderately sandy material on
<br />alluvial fans and foot slopes. Slopes range from 2 to 6
<br />percent. The mean annual precipitation is 17 inches, and
<br />the mean annual temperature is 51 degrees F.
<br />Bayard soils are similar to Manter, Paoli, Laird, and
<br />Kim soils. They are near Kim and Manter soils. Manter
<br />soils have a sandy loam B2t horizon. Paoli soils have an
<br />A horizon that is more than 20 inches thick. Laird soils
<br />have a Cca horizon that has a very high content of lime.
<br />Kim soils are loamy.
<br />Typical pedon of Bayard fine sandy loam, 2 to 6
<br />percent slopes, in grass about 5 miles west and 1 mile
<br />south of Wray, 800 feet south and 800 feet east of the
<br />northwest corner of sec. 17, T. 1 N., R. 44 W.
<br />A1-0 to 5 inches; grayish brown (10YR 5/2) fine sandy
<br />loam, very dark grayish brown (10YR 3/2) moist;
<br />moderate medium granular structure; soft, very
<br />friable, nonsticky and nonplastic; many very fine and
<br />fine roots; mildly alkaline; clear smooth boundary.
<br />AC-5 to 15 inches; grayish brown (10YR 5/2) fine
<br />sandy loam, very dark grayish brown (10YR 3/2)
<br />moist; moderate medium subangular blocky
<br />structure; hard, very friable, nonsticky and
<br />nonplastic; common very fine and fine roots; mildly
<br />alkaline; clear wavy boundary.

<br />C1ca -15 to 21 inches; pale brown (10YR 6/3) fine
<br />sandy loam, dark brown (10YR 4/3) moist; weak
<br />medium subangular blocky structure; slightly hard,
<br />very friable, nonsticky and nonplastic; common very
<br />fine and fine roots; violently effervescent; few fine
<br />rounded masses of lime; moderately alkaline; clear
<br />wavy boundary.
<br />C2ca -21 to 36 inches; very pale brown (10YR 7/3) fine
<br />sandy loam, brown (10YR 5/3) moist; weak coarse
<br />subangular blocky structure; slightly hard, very
<br />friable, nonsticky and nonplastic; few very fine and
<br />fine roots; violently effervescent; few medium soft
<br />masses of lime; gradual wavy boundary.
<br />C3 -36 to 60 inches; very pale brown (10YR 7/3) loamy
<br />fine sand, brown (10YR 5/3) moist; single grain;
<br />loose; few very fine and fine roots; violently
<br />effervescent; moderately alkaline.
<br />The thickness of the mollic epipedon is.8 to 20 inches.
<br />The content of gravel and pebbles ranges from 0 to 15
<br />percent. The A horizon is neutral or mildly alkaline. The
<br />depth to lime ranges from 8 to 18 inches.
<br />Canyon series
<br />The Canyon series consists of shallow, well drained
<br />soils that formed in calcareous, loamy material that
<br />weathered from highly calcareous sandstone. Canyon
<br />soils are on hills, knolls, and ridges. Slopes range from 1
<br />to 25 percent. The mean annual precipitation is 17
<br />inches, and the mean annual temperature is 51 degrees
<br />F.
<br />Canyon soils are near Kim, Bayard, Colby, and Midway
<br />soils. Kim soils are deep and loamy. Bayard soils are
<br />deep fine sandy barns. Colby soils are deep and silty.
<br />Midway soils are shallow and clayey.
<br />Typical pedon of Canyon loam, in an area of Canyon -
<br />Dioxice complex, 1 to 9 percent slopes, in native grass
<br />about 19 miles north of Yuma, 390 feet south and 20
<br />feet east of the northwest corner of sec. 14, T. 5 N., R.
<br />48 W.
<br />A1-0 to 5 inches; grayish brown (10YR 5/2) loam, very
<br />dark grayish brown (10YR 3/2) moist; weak fine
<br />granular structure; slightly hard, very friable,
<br />nonsticky and slightly plastic; many very fine and
<br />fine roots; violently effervescent; moderately
<br />alkaline; clear smooth boundary.
<br />AC -5 to 8 inches; grayish brown (10YR 5/2) loam, dark
<br />grayish brown (10YR 4/2) moist; weak fine
<br />subangular blocky structure parting to weak fine
<br />granular; slightly hard, very friable, slightly sticky and
<br />slightly plastic; many very fine and fine roots;
<br />violently effervescent; moderately alkaline; clear
<br />smooth boundary.
<br />C1ca -8 to 12 inches; light brownish gray (10YR 6/2)
<br />loam, dark grayish brown (10YR 4/2) moist;
