9.57 VEG CHINA CLAY SPOIL (vCC) (5015)


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: 5 well aerated made ground soils Permeable or moderately permeable soils that are not wet within 70 cm for more than 90 days nor within 40 cm for more than 30 days in most years. They are identified from one of the two following sets of characteristics: EITHER At least 60 cm of superficial material that shows no contemporary evidence of wetness within 40 cm depth and contains no layers, 15 cm or more thick, that are slightly or very slightly porous with high packing density. OR A coherent, consolidated man-made substrate at 40 to 60 cm depth that is directly overlain by material showing no contemporary evidence of wetness and containing no layers, 15 cm or more thick, that are slightly or very slightly porous with high packing density. Well aerated soils are free draining and relatively easily rootable to at least 40 cm depth, but have a significant leaching potential.
Soil Subgroup: 7 slightly acid, base-poor well aerated made ground soils Soils differentiated in slightly acid subgroups are defined as having a pH (in water, 1:2.5) of less than 6.5 to at least 10 cm depth and no layer more than 15 cm thick with a pH of 6.5 or more at any point within 80 cm depth. They occur only in base-poor subgroups and represent a critical stage of soil development between the leached and acid-humose condition. Slightly acid soils support relatively fragile ecosystems that are particularly sensitive to acidification. Lacking, between the base of the contemporary topsoil and 80 cm 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.
