title: Variations of organic carbon stock in reclaimed estuarine soils (Villaviciosa estuary, NW Spain).
abstract: A study was carried out in the Villaviciosa Estuary (Asturias, NW Spain) to determine the effects of polderization on soil properties and soil organic carbon content. The results showed that the polderized soils were more acidic and contained less carbonates and a higher soil organic carbon (SOC) content than the natural soils. The organic carbon stock in the reclaimed soils ranged from 83.2 to 91.8 t ha(-1), whereas in natural soils was approximately 43.7 t ha(-1). The degree of humification of the surface humic acids also indicated that the stability and degree of decomposition of the organic matter was higher in the reclaimed soils than in natural soils.
