ResumenIn general, gypsic soils from the study area (Southeast Spain) have low organic matter content. The organic matter concentrations range between 1 and 2% in the topsoil and from 0.25 to 1% in the underlying horizons. Under these conditions, the post-mining soil rehabilitation is hampered because the original source of soil has been removed and replaced by alternative “soil-forming materials” which are intended to represent suitable substrate for plant growth. An important limitation of these materials is their inherent poor structure, mainly because of their low content of organic matter. In these cases, the development of soil structure can be accelerated through the use of organic amendments. However, not all organic amendments are equally beneficial and there is classical controversy on their suitability as starting materials for the formation of humic substances.
