11 Sandy and poorly developed soils on lunettes, dunes and sand seets (siliceous) on Quaternary aeolian sediments

These soils are generally sandy and unconsolidated (loose) with organic matter in variable amounts acting as the binding agent for the surface being the only significant pedological development in the surface soil (providing some structure). The subsurface soil and subsoil is generally deep (>100 cm) on dunes, bleached and loosely to weakly coherent. Depth to a pan, consolidated sand or clay rich sediment will generally depend on topographic position with less unconsolidated sand depth in the lower positions. On the siliceous deposits nutrient availability is very low and has low retention given the high sand content and high internal drainage (unless restricted by other materials or high watertables either inland or at sea level). Notable characteristics are the light (sandy) textures, held only by organic matter at the surface with some cementation and possibly clay at depth, rapid permeability and low nutrient and water holding capacity.
