    Ap—0 to 8 centimeters (0.0 to 3.1 inches); light brownish gray (10YR 6/2), dark grayish brown (10YR 4/2), moist; silt loam; weak very fine granular structure; soft, very friable; Ksat of 28.225 um/s; moderately rapid permeability; fragments; noneffervescent, by hcl, unspecified; clear smooth boundary. Lab sample # 40A29934
    Bt1—8 to 15 centimeters (3.1 to 5.9 inches); grayish brown (10YR 5/2), very dark grayish brown (10YR 3/2), moist; silty clay loam; weak coarse prismatic parts to moderate coarse subangular blocky structure; very hard, firm; Ksat of 9.17 um/s; moderate permeability; gray (10YR 6/1) and white (10YR 8/1) on horizontal faces of peds; fragments; noneffervescent, by hcl, unspecified; clear smooth boundary. Lab sample # 40A29935
    Bt2—15 to 28 centimeters (5.9 to 11.0 inches); grayish brown (10YR 5/2), very dark grayish brown (10YR 3/2), moist; silty clay loam; strong fine prismatic parts to strong medium angular blocky structure; hard, friable; Ksat of 2.82 um/s; moderately slow permeability; 10 percent ; fragments; noneffervescent, by hcl, unspecified; clear smooth boundary. Lab sample # 40A29936. patchy - phpvsfiid 1202592; patchy - phpvsfiid 1202592
    Btb—28 to 42 centimeters (11.0 to 16.5 inches); gray (10YR 5/1), very dark gray (10YR 3/1), moist; silty clay loam; moderate medium prismatic parts to strong fine angular blocky structure; hard, friable; Ksat of 0.915 um/s; slow permeability; fragments; noneffervescent, by hcl, unspecified; abrupt smooth boundary. Lab sample # 40A29937
    Btkb1—42 to 50 centimeters (16.5 to 19.7 inches); light brownish gray (10YR 6/2) and pale brown (10YR 6/3), very dark grayish brown (10YR 3/2) and grayish brown (10YR 5/2), moist; silty clay loam; moderate medium prismatic parts to strong fine angular blocky structure; hard, friable; Ksat of 0.915 um/s; slow permeability; 1 percent carbonate concretions; fragments; strong effervescence, by hcl, unspecified; gradual smooth boundary. Lab sample # 40A29938. Tonhautchen are moderately thick and relatively prominent; variation in color is due to the intense worm working in which materials from the horizons above have been thoroughly worked into this horizon. In addition it appears that some of the material from the above horizon have been washed down into structural cracks and now coat the surfaces of the aggregates there.
    Btkb2—50 to 66 centimeters (19.7 to 26.0 inches); light brownish gray (10YR 6/2), grayish brown (10YR 5/2), moist; silty clay loam; weak coarse prismatic parts to moderate medium angular blocky structure; hard, friable; Ksat of 2.82 um/s; moderately slow permeability; 3 percent prominent clay films; 3 percent carbonate masses and carbonate concretions and worm casts; fragments; strong effervescence, by hcl, unspecified. Lab sample # 40A29939. The horizon contains moderate amounts of accumulated lime chiefly as lime flour and as concretions; Tonhautchen are moderately prominent; this horizon is also thoroughly reworked by worms and contains casts and channels filled with darker materials from the horizons above.
    Btkb3—66 to 86 centimeters (26.0 to 33.9 inches); light gray (10YR 7/2), light brownish gray (10YR 6/2), moist; silt loam; weak coarse subangular blocky structure; hard, friable; Ksat of 2.82 um/s; moderately slow permeability; clay films; worm casts and carbonate threads and carbonate masses and carbonate concretions; fragments; strong effervescence, by hcl, unspecified; gradual smooth boundary. Lab sample # 40A29940. The horizon contains much accumulated lime chiefly as lime flour but with some concretions and mycelia; Tonhautchen are very thin and patchy; the horizon has been partially reworked by worms, and dark channel fillings and worm casts occur throughout it.; patchy - phpvsfiid 1202589; patchy - phpvsfiid 1202589
    Bk—86 to 107 centimeters (33.9 to 42.1 inches); very pale brown (10YR 7/3), pale brown (10YR 6/3), moist; silt loam; massive, and weak coarse subangular blocky; slightly hard, very friable; Ksat of 9.17 um/s; moderate permeability; 3 percent carbonate concretions and carbonate threads; fragments; strong effervescence, by hcl, unspecified; gradual smooth boundary. Lab sample # 40A29941. The horizon contains moderate amounts of concretionary and mycelial lime but somewhat less than the horizon above.
    C—107 to 127 centimeters (42.1 to 50.0 inches); very pale brown (10YR 7/3), pale brown (10YR 6/3), moist; silt loam; massive; slightly hard, very friable; Ksat of 9.17 um/s; moderate permeability; fragments; strong effervescence, by hcl, unspecified. Lab sample # 40A29942. The horizon contains moderate amounts of accumulated lime chiefly as lime flour.
