12 Sandy, saline and poorly developed soils on lunettes, dunes and sand sheets, (calcareous) 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 calcareous deposits nutrient availability is low to moderate and has relatively 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). Saline and calcareous soils are included in this grouping. 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 moderate nutrient and low water holding capacity. These soils are alkaline, generally calcareous and close proximity to the coast.
