    Ap1—0 to 26 centimeters (0.0 to 10.2 inches); brown (10YR 4/3) crushed silt loam; 3 percent sand; 79 percent silt; 18 percent clay; weak fine granular structure; friable; 6.0 very fine roots throughout and 6.0 medium roots throughout and 6.0 fine roots throughout; 5 percent fine prominent spherical strong brown (7.5YR 5/6), moist, masses of oxidized iron with clear boundaries throughout; 3 percent by volume 2-3-5 millimeter mixed fragments; neutral, pH 6.7, hellige-truog; gradual smooth boundary. Lab sample # 11N00564; observed in pit, small
    Ap2—26 to 51 centimeters (10.2 to 20.1 inches); brown (10YR 5/3) crushed silt loam; 3 percent sand; 76 percent silt; 21 percent clay; moderate medium platy structure; friable; 6.0 very fine roots throughout and 6.0 fine roots throughout; 10 percent medium prominent spherical yellowish brown (10YR 5/8), moist, masses of oxidized iron with clear boundaries throughout and 10 percent fine distinct spherical grayish brown (10YR 5/2), moist, masses of reduced iron with clear boundaries throughout; 3 percent by volume 2-3-5 millimeter mixed fragments; neutral, pH 7.1, hellige-truog; gradual smooth boundary.

    Bw—51 to 203 centimeters (20.1 to 79.9 inches); dark grayish brown (10YR 4/2) broken face gravelly loam; 35 percent sand; 33 percent silt; 32 percent clay; massive; very firm; 0.9 fine roots between peds; 10 percent fine prominent spherical yellowish brown (10YR 5/8), moist, masses of oxidized iron with clear boundaries throughout and 10 percent coarse distinct spherical grayish brown (10YR 5/2), moist, masses of reduced iron with clear boundaries throughout and 10 percent fine distinct clay depletions on faces of peds and 10 percent coarse distinct clay depletions on faces of peds; 5 percent by volume nonflat subrounded 2-2-5 millimeter shale, calcareous fragments and 15 percent by volume nonflat subrounded 2-5-15 millimeter limestone, unspecified fragments; slightly alkaline, pH 7.8, hellige-truog. Lab sample # 11N00566; observed in pit, small. Due to the nature of the reclaimed material this horizon also contained strong coarse angular blocky structure. When this structure was added to the horizon, Nasis 6 recognized this horizon as two separate horizons. So it was removed and added to the text notes. Occasional cobbles and stones are found in this horizon
