SOIL 
HORIZON DESCRIPTION:

O:           0-2 cm; Leaves, pods, branches

Ah1:       2-14/22 cm; Black (10YR 2/1); silt loam; no rock fragments; strong very fine granular structure; very friable; many fine and very fine roots; clear and wavy to:

Ah2:       14/22-47 cm; Very dark grey (10YR 3/1); silt loam; no rock fragments; strong very fine subangular blocky structure; friable to firm; common fine and very fine roots, few coarse and medium roots; clear and smooth to.

2Bw/2R: 47-62 cm; Brown to dark brown (10YR 4/3) and very dark grey (10YR 3/1); loam; 40-50% weathered angular andesitic rock fragments; strong fine angular blocky to granular structure; friable; few roots of all sizes; abrupt and smooth to:

2R:         > 62 cm; Continuous, partly weathered, andesitic rock.

 

WRB (2001): mollic horizon (0-47 cm); cambic horizon (47-62 cm); no vitric horizon (Ah2 meets P-retention requirement, but is too shallow to be vitric); >40% silt between 2 and 47 cm; continuous rock at 62 cm depth:

Silti-Endoleptic Phaeozem

ST (1999): mollic epipedon (0-47 cm); cambic horizon (47-62 cm); no andic soil properties (Alo + Feo < 0.4%):

Fine-silty, mixed, superactive mesic Vitrandic Haploxeroll
(if volcanic glass content is 13% or more)

Fine-silty, mixed, superactive mesic Ultic Haploxeroll
(if volcanic glass content <13%
