We established an experimental field in Cañamero?s raña (SW Spain) for the study of the recovery of degraded Mediterranean Ultisols due to inappropriate agricultural use. The experiment involved the application of liming materials, based on ?sugar foam? alone or with ?phosphogypsum? and the implementation of a dehesa, through the reforestation with Quercus suber L. or Quercus faginea Lam. with or without a leguminous shrub of Adenocarpus telonensis (Loisel) D.C. This Mediterranean ecosystem allows the coexistent of a sustainable agroforestry crop, common in the study area, with a high range of biodiversity. After 3 years of the establishment of the experiment, the mixture with ?sugar foam? and ?phosphogypsum? was effective in reducing the exchange Al and increase the exchange Ca to a depth of 50 cm, while the ?sugar foam? affected the 35 cm depth of the soil, where the argillic horizon (with low permeability) begins. However, the amendments had a weak influence on the development of the trees, and this result contrasted with the positive effect exerted both amendments on the biomass production of pasture and forage crops in a field experiment attached to this since the first year of its application. Adenocarpus scrub grew rapidly in all cases, especially in amended plots, and had a negative impact on the development of the trees due to water competition in the dry season (June to October). | |
