Resumen
From a cartographic soils study and a systematical sampling of superficial horizons in the Sierra Magina natural park, we have analyzed the influence of the rock, as original material of the soil, in the differentiation of reference levels of quality of soil and in its degree of modification. Twelve characteristics as indicative of soil quality let us to establish four reference levels of soil quality: Mollic Leptosol on calcareous-dolomitic tectonized rocs, Haplic Phaeozem on doline, Mollic Leptosol on slope calcareous deposits and Mollic Leptosol on calcareous lapiaz. Cartographic soil units on calcareous colluvial slope deposits and on lapiaz calcareous compact are the most susceptible to modify the quality of soils, fundamentally by the decrease of the organic remains contribution in the first case and by the erosion processes accelerated in the second case. The decrease in the organic carbon content, nitrogen and clay, as well as the increase in the value and chroma of the soil color are the diagnostic features more evident of the deterioration of the quality in cartographic soil units.
