    A—0 to 38 centimeters (0.0 to 15.0 inches); black (10YR 2/1) silty clay; weak medium angular blocky structure; slightly hard; fragments; abrupt smooth boundary. Lab sample # NDSU1694, NDSU1693; dry when described;
    O—13 to 0 centimeters (5.1 to 0.0 inches); black (10YR 2/1) peat; soft; fragments; abrupt smooth boundary.; dry when described;. Soils were sampled for laboratory analysis in 15cm increments. Profile was dry to surface when sampled. Coarse fragments 1-5%. KCI extractable iron tests were performed on 0-15 and 45-60 cm increments. Both tested negative.
    E—38 to 69 centimeters (15.0 to 27.2 inches); very dark grayish brown (10YR 3/2) silty clay loam; weak fine platy structure; soft; fragments; abrupt smooth boundary. Lab sample # NDSU1695, NDSU1696; dry when described;
    Bt—69 to 229 centimeters (27.2 to 90.2 inches); black (10YR 2/1) clay; very firm; fragments. Lab sample # NDSU1697, NDSU1698; dry when described;
