The data entered in the pedon horizon lab data results table for this horizon are from KSSL lab pedon id 11N0419, sample # 11N02171.; The horizon designation was changed from Bz3 to By3 because the lab data pH values clues us in that what is being called salt accumulations are more likely gypsum accumulations because the pH values are very high.; The salt crystals have been changed to gypsum crystals based on the lab data pH values being very high.

Bky—85 to 103 centimeters (33.5 to 40.6 inches);, brown (10YR 5/3) crushed, moist; silty clay loam; 38 percent clay; moderate medium subangular blocky structure; 3.0 very fine roots throughout and 3.0 fine roots throughout; 2 percent fine distinct irregular weakly coherent cemented carbonate nodules with clear boundaries in matrix and 5 percent fine distinct irregular weakly coherent cemented gypsum crystals, unspecified with clear boundaries in matrix and 2 percent medium distinct irregular weakly coherent cemented carbonate nodules with clear boundaries in matrix and 5 percent medium distinct irregular weakly coherent cemented gypsum crystals, unspecified with clear boundaries in matrix; fragments; slight effervescence, by hcl, 1n; gradual wavy boundary.; observed in pit, small. The data entered in the pedon horizon lab data results table for this horizon are from KSSL lab pedon id 11N0419, sample # 11N02172.; The horizon designation was changed from Bkz1 to Bky1 because the lab data pH values clues us in that what is being called salt accumulations are more likely gypsum accumulations because the pH values are very high.; The salt crystals have been changed to gypsum crystals based on the lab data pH values being very high.

Bk—103 to 140 centimeters (40.6 to 55.1 inches);, brown (10YR 5/3) crushed, moist; silty clay loam; 36 percent clay; moderate medium subangular blocky structure; 3.0 very fine roots throughout and 3.0 fine roots throughout; 3 percent coarse distinct irregular strongly coherent cemented carbonate nodules with clear boundaries in matrix and 3 percent medium distinct irregular strongly coherent cemented carbonate nodules with clear boundaries in matrix and 8 percent medium distinct irregular weakly coherent cemented carbonate masses with clear boundaries in matrix; fragments; slight effervescence, by hcl, 1n; clear wavy boundary.; observed in pit, small. The data entered in the pedon horizon lab data results table for this horizon are from KSSL lab pedon id 11N0419, sample # 11N02173.; The horizon designation was changed from Bkz2 to Bk because there are no salt accumulations described for this horizon.

2C1—140 to 191 centimeters (55.1 to 75.2 inches);, grayish brown (10YR 5/2) crushed, moist; sandy loam; 15 percent clay; massive; 0.5 very fine roots throughout and 0.5 fine roots throughout; 4 percent fine distinct irregular weakly coherent cemented black (10YR 2/1), moist, manganese masses with clear boundaries in matrix and 5 percent medium prominent irregular weakly coherent cemented yellowish brown (10YR 5/6), moist, masses of oxidized iron with clear boundaries in matrix and 5 percent fine distinct irregular weakly coherent cemented dark yellowish brown (10YR 4/6), moist, masses of oxidized iron with clear boundaries in matrix; fragments; very slight effervescence, by hcl, 1n; clear wavy boundary.; observed in pit, small.
