SOIL HORIZON DESCRIPTION:

O:      0-2 cm;

Ah:    2-17 cm; Black (10YR 2/1), wet, very weak consistence, weakly developed fine granular peds, sandy' loam, slightly stony, small subangular stones, abundant roots, clear and wavy boundary with next horizon

AB:    17-67 cm; Dark reddish brown (5YR 2.5/3), wet, moderately weak consistence, moderately developed medium granular peds, sandy loam, very stony (60 %), large and very large subangular and subrounded stones, abundant woody roots, thixotropic, diffuse and wavy transition to the next horizon.

Bw:    67-92 cm; Dark yellowish brown (10YR 4/4), slightly moist, moderately firm consistence, weakly developed subangular blocky peds, clay loam, very stony (80 %), large and very large subangu1ar and subrounded stones, few woody roots, thixotropic; diffuse and irregular transition to the substrate layer

C:      > 92 cm; Weathered andesite, large and very large stones.

 

WRB (2001): umbric horizon (0-67 cm); vitric horizon (2-92 cm); no andic horizon because of too low clay content; >40% coarse fragments between 17 and 92 cm:

Umbri-Vitric Andosol (Pachic and Skeletic)

ST (1999): umbric epipedon (0-67 cm); cambic horizon (67-92 cm); andic soil properties between 2 and 97 cm; KCl-extractable Al > 2.0 cmol(+) kg-1 is assumed to occur between 25 and 50 cm because of high total acidity; >35% coarse fragments between 17 and 92 cm:

Medial-skeletal, mixed, mesic Alic Hapludand
