A—0 to 3 centimeters (0.0 to 1.2 inches);, dark brown (10YR 3/3) crushed, moist; loam; 16 percent clay; weak fine granular structure; 5.0 very fine roots throughout and 5.0 fine roots throughout; fragments; noneffervescent, by hcl, 1n; diffuse wavy boundary.; moist when described; observed in pit, small. The data entered in the pedon horizon lab data results table for this horizon are from KSSL lab pedon id 11N0423, sample # 11N02197.; The horizon designation was changed from A1 to A.

Bw—3 to 13 centimeters (1.2 to 5.1 inches);, very dark brown (10YR 2/2) crushed, moist; clay loam; 32 percent clay; moderate medium prismatic parts to moderate fine subangular blocky structure; 5.0 very fine roots throughout and 5.0 fine roots throughout; fragments; noneffervescent, by hcl, 1n; clear wavy boundary.; moist when described; observed in pit, small. The data entered in the pedon horizon lab data results table for this horizon are from KSSL lab pedon id 11N0423, sample # 11N02198.; The horizon designation was changed from A2 to Bw because this horizon has more developed than an A horizon and that is supported by the soil structure and color.

Bk—13 to 42 centimeters (5.1 to 16.5 inches);, very dark brown (10YR 2/2) crushed, moist; clay loam; 34 percent clay; strong medium prismatic parts to moderate medium subangular blocky structure; 5.0 very fine roots throughout and 5.0 fine roots throughout; fragments; very slight effervescence, by hcl, 1n; clear wavy boundary.; moist when described; observed in pit, small. The data entered in the pedon horizon lab data results table for this horizon are from KSSL lab pedon id 11N0423, sample # 11N02199.; The horizon designation was changed from Bw to Bk because there are CaCO3 masses present.

Bky—42 to 68 centimeters (16.5 to 26.8 inches);, dark grayish brown (10YR 4/2) crushed, moist; loam; 26 percent clay; strong medium prismatic parts to moderate medium subangular blocky structure; 3.0 very fine roots throughout and 3.0 fine roots throughout; 3 percent fine distinct irregular weakly coherent cemented gypsum masses in matrix and 15 percent medium distinct threadlike weakly coherent cemented carbonate masses in matrix; fragments; strong effervescence, by hcl, 1n; gradual wavy boundary.; moist when described; observed in pit, small. The data entered in the pedon horizon lab data results table for this horizon are from KSSL lab pedon id 11N0423, sample # 11N02200.; The horizon designation was changed from Bkz1 to Bky because the described salt crystals are actually gypsum masses.

B'k1—68 to 90 centimeters (26.8 to 35.4 inches);, dark grayish brown (10YR 4/2) crushed, moist; clay loam; 32 percent clay; strong medium prismatic parts to moderate medium subangular blocky structure; 3.0 very fine roots throughout and 3.0 fine roots throughout; 30 percent distinct pressure faces on vertical faces of peds; 3 percent coarse distinct irregular weakly coherent cemented carbonate masses in matrix; fragments; strong effervescence, by hcl, 1n; gradual wavy boundary.; moist when described; observed in pit, small. The data entered in the pedon horizon lab data results table for this horizon are from KSSL lab pedon id 11N0423, sample # 11N02201.; The horizon designation was changed from Bkz2 to B'k1 because there are no salt crystals described.; continuous - phpvsfiid 592023; continuous - phpvsfiid 592023

B'k2—90 to 119 centimeters (35.4 to 46.9 inches);, grayish brown (10YR 5/2) crushed, moist; clay loam; 38 percent clay; strong medium prismatic parts to moderate medium subangular blocky structure; 0.5 very fine roots throughout and 0.5 fine roots throughout; 30 percent distinct pressure faces on vertical faces of peds; 5 percent coarse distinct irregular weakly coherent cemented carbonate masses in matrix and 1 percent medium distinct irregular weakly coherent cemented carbonate nodules in matrix; fragments; violent effervescence, by hcl, 1n; clear wavy boundary.; moist when described; observed in pit, small. The data entered in the pedon horizon lab data results table for this horizon are from KSSL lab pedon id 11N0423, sample # 11N02202.; The horizon designation was changed from Bkz3 to B'k2 because there are no salt crystals described.; continuous - phpvsfiid 592024; continuous - phpvsfiid 592024

BC—119 to 131 centimeters (46.9 to 51.6 inches);, grayish brown (2.5Y 5/2) crushed, moist; clay loam; 38 percent clay; strong medium prismatic parts to moderate medium subangular blocky structure; 3 percent medium distinct irregular black (2.5Y 2.5/1), moist, manganese masses in matrix and 4 percent medium distinct irregular dark yellowish brown (10YR 4/6), moist, masses of reduced iron in matrix; 5 percent by volume nonflat subrounded very strongly coherent cemented 2-?-20 millimeter metamorphic, unspecified fragments; noneffervescent, by hcl, 1n; clear wavy boundary.; moist when described; observed in pit, small. The data entered in the pedon horizon lab data results table for this horizon are from KSSL lab pedon id 11N0423, sample # 11N02203.

2C1—131 to 144 centimeters (51.6 to 56.7 inches);, light brownish gray (2.5Y 6/2) crushed, moist; sand; 4 percent clay; single grain; 2 percent medium distinct irregular yellowish brown (10YR 5/6), moist, masses of reduced iron in matrix and 4 percent medium faint irregular dark yellowish brown (10YR 4/4), moist, masses of reduced iron in matrix; 5 percent by volume nonflat subrounded very strongly coherent cemented 2-?-5 millimeter igneous, unspecified fragments; noneffervescent, by hcl, 1n; gradual wavy boundary.; wet when described; observed in pit, small. The data entered in the pedon horizon lab data results table for this horizon are from KSSL lab pedon id 11N0423, sample # 11N02204.

2C2—144 to 202 centimeters (56.7 to 79.5 inches);, pale brown (10YR 6/3) crushed, moist; sand; 4 percent clay; single grain; 10 percent medium and coarse distinct irregular yellowish brown (10YR 5/6), moist, masses of reduced iron in matrix; 4 percent by volume nonflat subrounded very strongly coherent cemented 2-?-5 millimeter igneous, unspecified fragments and 4 percent by volume nonflat subrounded very strongly coherent cemented 5-?-20 millimeter igneous, unspecified fragments; noneffervescent, by hcl, 1n.; wet when described; observed in pit, small. The data entered in the pedon horizon lab data results table for this horizon are from KSSL lab pedon id 11N0423, sample # 11N02205.
