A—0 to 10 centimeters (0.0 to 3.9 inches); very dark grayish brown (10YR 3/2) interior, grayish brown (10YR 5/2) interior, dry; fine sandy loam; soft, very friable, nonsticky, nonplastic; fragments; very strongly acid, pH 4.8, pH meter; clear irregular boundary. Lab sample # 40A33987. plentiful tree, shrub & grass roots; structureless but slightly cohesive

E—10 to 25 centimeters (3.9 to 9.8 inches); grayish brown (10YR 5/2) interior, light brownish gray (10YR 6/2) interior, dry; fine sandy loam; soft, very friable, nonsticky, nonplastic; 5.5 roots; 5.5 fine vesicular pores; 1 percent worm casts; fragments; strongly acid, pH 5.3, pH meter; clear smooth boundary. Lab sample # 40A33988. contains occasional strongly cemented subrounded dark reddish brn iron concretions; few worm casts concentrations; many roots

B/Et—25 to 51 centimeters (9.8 to 20.1 inches); yellowish brown (10YR 5/6) interior, light yellowish brown (10YR 6/4) interior, dry; fine sandy loam; weak blocky structure; hard, friable, slightly sticky, slightly plastic; 5.5 roots; 1 percent worm casts; fragments; very strongly acid, pH 4.6, pH meter; gradual smooth boundary. Lab sample # 40A33989. many fine continuous pores; occasional roundish strongly cemented, reddish iron concretions; distinctly and finely mottled brnish yllw & gray heavy FSL; few worm casts concentrations; many roots

Lab sample # 40A33990. distinctly & coarsely mottled light gray, brnish yllw & strong brn FSL. occasional yllwish red med-sized mottles comprising soil peds that have weakly cemented cntrs. that can be crushed between fingers; common tree roots.
