Soil Series

9.44 VEG SHALE SPOIL (vSS) (5029)


Definition
Major soil group: 09 made ground soils Soils formed in a significant thickness of either artificial man-made material or former soil material or geological substrate that has undergone mechanical removal, transport and replacement.
Soil Group: 4 dense made ground soils Soils described as dense contain a subsurface layer that is at least 15 cm thick, starts within 40 cm depth, is slightly or very slightly porous with high packing density and shows no contemporary evidence of wetness in or above it. IN ADDITION, they are formed on sloping sites of at least 3 degrees. Dense soils tend to be droughty with a low leaching and high erosion potential because their structural conditions restrict rooting and the downward percolation of water, whereas their position on sloping ground means that a relatively large proportion of rainfall is lost as surface run-off.
Soil Subgroup: 4 acid-humose, base-rich dense made ground soils These soils are defined as having superficial F, H, humose Ah, or some combination of these horizons at least 5 cm thick, and a pH (in water, 1:2.5) of less than 5.5 throughout the upper 10 cm. Acid-humose subgroups distinguish soils of low overall biological activity in which the upper parts are acid, depleted of bases (usually less than about 50% base saturated) and have a significant accumulation of poorly incorporated, only slightly transformed organic matter in various stages of humification. The superficial organic layers, often termed mor or moder, are rich in inherited humin and have very slow mineralisation and cycling of nitrogen. Soils which have, between the base of the contemporary topsoil and 80cm or a consolidated coherent man-made substrate, whichever is shallower, a layer that is at least 15 cm thick and comprises EITHER, calcareous material OR earthy material with at least 1% organic matter or a clay content more than 18%, OR base-rich rock waste or man-made material.
