Soil Profile Morphology:
|A1||0-20 cm||Dark gray (10YR4/1 moist), grayish brown (10YR5/2 dry), fine sandy loam; moderately pedal; weak to firm consistence; pH 5.5:|
SW71 Profile. Note: Surface (A1) horizon has been stripped from the soil profile
|A2e||20-50/60 cm||Light brownish gray (2.5Y6/2 moist), conspicuously bleached (2.5Y8/1 dry); fine sandy loam; hard setting; common (<20%), fine ferromanganiferous gravel (mostly not magnetic) sporadic and not in thick layer; very firm consistence; clear to gradual change (incipient B1) to; pH 5.8:|
|B21ss||50/60-100/120 cm||Dark yellowish brown (10YR3/4 moist and dry); many (~25%), faint, fine to coarse (5-20 mm) yellow brown/ dark red mottles; heavy clay; coarse (50-120 mm) prismatic, parting to thick lenticular or angular blocky structure; slickensides; diffuse yellower change to; pH 6.0:|
|C/B||100/120+ cm||Brownish yellow (10YR6/8 moist) to yellow (10YR8/8 dry); fine sandy with white (10YR8/1 moist) and very dark gray (5YR3/1 moist) ped faces; below 150 cm, extremely hard to break with geopick; cemented ferruginised sandstone.|
|The surface soil is strongly acid. The deeper subsoil is moderately acid.||Salinity rating is low in the surface becoming very low in the subsoil.||
||The clay content increases markedly at the A/B boundary.|
