    B1—13 to 25 centimeters (5.1 to 9.8 inches); brown (7.5YR 4/4) silt loam; weak and moderate medium subangular blocky structure; friable; 21.0 roots; faint pale brown (10YR 6/3), moist, silt coats on faces of peds; fragments; slightly acid, pH 6.5, hellige-truog; clear smooth boundary. Lab sample # 40A11040
    B21—25 to 46 centimeters (9.8 to 18.1 inches); brown (7.5YR 4/4) silty clay loam; strong medium subangular blocky structure; firm; 21.0 roots; faint brown (7.5YR 4/4), moist, clay films on faces of peds and faint light gray (10YR 7/1), dry, silt coats; fragments; slightly acid, pH 6.5, hellige-truog; gradual smooth boundary.
