Ap—0 to 9 centimeters (0.0 to 3.5 inches); pale brown (10YR 6/3), dark grayish brown (10YR 4/2), moist; silt loam; 3 percent yellowish brown (10YR 5/6) medium distinct mottles; weak very fine granular structure; soft, very friable; Ksat of 9.17 um/s; moderate permeability; pale brown (10YR 6/3), dry, and dark brown (10YR 3/3), moist, and very pale brown (10YR 7/3), dry,; fragments; noneffervescent, by hcl, unspecified; clear smooth boundary. Lab sample # 40A29925
A—9 to 20 centimeters (3.5 to 7.9 inches); brown (10YR 5/3), dark brown (10YR 3/3), moist; silt loam; weak coarse subangular blocky structure; slightly hard, friable; Ksat of 9.17 um/s; moderate permeability; fragments; noneffervescent, by hcl, unspecified; abrupt wavy boundary. Lab sample # 40A29926. The structure in this horizon may be influenced by tillage; where observed in the cut of the pit, this horizon had an indefinite and irregular zone near its base that had characteristics of an E (or A2) horizon. The color graded in these areas to 10YR 7/3 to 6/3 dry but when moist was about the same color as is described above. It had a vesicular appearance and was slightly lighter in texture. In other places no definite zone of lighter color or vesicular nature could be seen but aggregates frequently were flecked with spots of 10YR 8/2.
Bt—20 to 32 centimeters (7.9 to 12.6 inches); grayish brown (10YR 5/2), very dark grayish brown (10YR 3/2), moist; silty clay loam; moderate and strong fine prismatic parts to moderate and strong fine subangular blocky structure; hard, firm; Ksat of 0.915 um/s; slow permeability; 10 percent ; fragments; noneffervescent, by hcl, unspecified; clear smooth boundary. Lab sample # 40A29927. patchy - phpvsfiid 1202587; patchy - phpvsfiid 1202587
Btb1—32 to 48 centimeters (12.6 to 18.9 inches); gray (10YR 5/1), very dark grayish brown (10YR 3/2), moist; silty clay; moderate medium prismatic parts to strong medium angular blocky structure; hard, firm; Ksat of 0.915 um/s; slow permeability; fragments; noneffervescent, by hcl, unspecified; abrupt smooth boundary. Lab sample # 40A29928. The horizon has thick prominent Clay skins; the structural cracks between the peds in this horizon are filled with lighter colored materials washed from the horizon above.
Btb2—48 to 56 centimeters (18.9 to 22.0 inches); grayish brown (10YR 5/2), dark grayish brown (10YR 4/2), moist; silty clay loam; 3 percent dark yellowish brown (10YR 4/4) medium faint mottles; weak coarse prismatic parts to moderate coarse subangular blocky structure; hard, friable; Ksat of 0.915 um/s; slow permeability; 1 percent carbonate concretions and carbonate threads; fragments; strong effervescence, by hcl, unspecified; gradual smooth boundary. Lab sample # 40A29929. The horizon has a few small calcium carbonate concretions and mycelia.
Bkb1—56 to 64 centimeters (22.0 to 25.2 inches); pale brown (10YR 6/3), brown (10YR 5/3), moist; silt loam; weak coarse prismatic parts to moderate coarse angular blocky structure; hard, friable; Ksat of 2.82 um/s; moderately slow permeability; fragments; strong effervescence, by hcl, unspecified; gradual smooth boundary. Lab sample # 40A29930. This horizon has been thoroughly reworked by worms and dark channels containing material of the horizons above occur prominently in it. There are some channel fillings between the peds of dark material apparently washed down from the preceding horizons.
Bkb2—64 to 69 centimeters (25.2 to 27.2 inches); light gray (10YR 7/2), light brownish gray (10YR 6/2), moist; silt loam; weak coarse prismatic parts to weak coarse subangular blocky structure; slightly hard, very friable; Ksat of 9.17 um/s; moderate permeability; fragments; strong effervescence, by hcl, unspecified; gradual smooth boundary. Lab sample # 40A29931. This horizon contains some accumulated lime but less than the horizon above or the horizon below; this horizon has been thoroughly reworked by worms, and worm casts and channels filled with darker materials from the horizons above are plentiful; some of the aggregate faces are coated with darker material apparently washed from the horizons above.
Bkb3—69 to 89 centimeters (27.2 to 35.0 inches); light gray (10YR 7/2), pale brown (10YR 6/3), moist; silt loam; weak coarse subangular blocky structure; hard, friable; Ksat of 9.17 um/s; moderate permeability; carbonate concretions and 1 percent worm casts and 3 percent carbonate masses and worm nodules; fragments; strong effervescence, by hcl, unspecified; gradual smooth boundary. Lab sample # 40A29932. The horizon contains moderate amounts of accumulated lime chiefly as lime flour but with some calcium carbonate concretions. The amount of lime is greater than in the horizon above or in the horizon below; there are a few worn casts and worm channel fillings in the horizon.
2C—89 to 117 centimeters (35.0 to 46.1 inches); very pale brown (10YR 8/3), pale brown (10YR 6/3), moist; coarse sandy loam; massive; slightly hard, very friable; Ksat of 28.225 um/s; moderately rapid permeability; carbonate threads and 3 percent carbonate masses and carbonate concretions; fragments; strong effervescence, by hcl, unspecified. Lab sample # 40A29933. The horizon contains moderate amounts of accumulated calcium carbonate as lime flour and as concretions and mycelia, but there is less than in the horizon above.
