Alfisols

Alfisols (grey-brown podsolics) An order of mineral soils that have clay-enriched or argillic B horizons; are alkaline to intermediate in reaction, with the base saturation in the B horizon more than 35 per cent; are usually derived from base-rich parent materials; and are drier than −15 bars moisture potential for at least three months when plants could grow. Alfisols occur under deciduous woodland or grassland in humid areas of the world and are generally productive agricultural soils. Brown earths are the equivalent in Britain.
