ST (1999): Medial, mixed, mesic Typic Fulvudand

Locality: Slovakia, Vtácnik Mountains,

Coordinates: X (S-JTS): 454933; Y (S-JTS): 1237126.

Altitude: 1235 m

Relief: steeply sloping hill-slope

Aspect: NE

Land use: woodland (Acer pseudoplatanus, Fagus sylvatica)

Parent material: pyroxenic andesite

SOIL HORIZON DESCRIPTION:

O:      0-5 cm;

Ah1:   5-10 cm; Black (10YR 2/1), moist; very weak consistence, weakly developed fine granular peds, sandy loam, moderately stony, medium subangular stones, abundant roots, clear and wavy boundary to the next horizon

Ah2:   10-30 cm; Very dark brown (10YR 2/2), moist; moderately weak consistence, moderately developed medium granular peds, sandy loam, moderately stony with medium and large subangular and angular stones, abundant roots, thixotropic, diffuse and wavy transition through AB layer to Bw horizon

AB:    30-45 cm; Very dark greyish brown (10YR 3/2), moist; moderately weak consistence, moderately developed medium granular and fine subangular peds, loam, moderately stony with medium and large sub-angular and angular stones, abundant roots, thixotropic;

Bw:    45-85 cm; Dark brown (10YR 3/3), slightly moist; moderately firm consistence, moderately developed medium granular and fine subangular peds, clay loam, very stony, medium and large subangular and angular stones, common woody roots, thixotropic, diffuse and wavy transition to the substrate through B/C layer;

B/C:   >85 cm; Dark yellowish brown (10YR 4/4), slightly moist; very firm consistence, moderately developed fine subangular peds, clay-loam, very stony, large subangular and angular stones, common woody roots, thixotropic.

 

 

WRB (2001): umbric horizon (0-45 cm); no melanic horizon because too low clay content in Ah1, Ah2 and AB horizons to meet the criteria for andic horizon; vitric horizon (5->85 cm); >40 coarse fragments below 45 cm depth; BS <50% throughout and <20% between 5 and 45 cm:

Umbri-Vitric Andosol (Endoskeletic and Hyperdystric)

ST (1999): umbric epipedon (0-45 cm); no melanic epipedon because melanic index is more than 1.7 between 5 and 35 cm (all other requirements apply); andic soil properties (5->85 cm):

Medial, mixed, mesic Typic Fulvudan
