The aim of this work was to develop a suitable index for characterizing the quality of soils in semiarid Mediterranean ecosystems. The preliminary estimate of the attributes involved in soil quality was made taking into account the opinion of experts and our own experience in such ecosystems. These attributes were based on different physical (granulometry, aggregate stability, water holding capacity...
This study analyses the loss of fertility in eroded soils, whose nutrients are retained behind check dams. The study was carried out in the basin of the River Quipar, which flows into the River Segura (SE Spain). In two projects carried out in 1962 and 1996, 425 check dams were constructed in an attempt to reduce sedimentation. Of these check dams, 18 were chosen as representative of the different...
This study aims to identify some of the factors contributing to the piping process in abandoned terraces in seven sites located in the Murcia Region (southeast Spain). The local landscape has the appearance of badland geomorphology, possessing deep valleys which until the 1970s were terraced and cultivated. The terraces have now been abandoned to the piping process. The research focuses on the relationship...
