We studied eighteen 300 m 2 plots in which 1 year-old seedlings had been planted after subsoiling on the contour. Plots were stratiﬁed according to aspect (north and south) and previous land use/parent material: shrubland on limestone (LM-SH), shrubland on gypsum rock (GY-SH), and cropland on colluvium (CO-AG). Soils developed on limestone and colluvium had average rooting depths of 27 and 37 cm, respectively, and mean concentrations of active lime and phosphorus (P) of 130 and 190 mg g -1 and 10 and 19 mg kg -1 , respectively. Soils developed on gypsum had a mean rooting depth of 26 cm, and a mean gypsum concentration of 73 %. Height and diameter of trees varied signiﬁcantly according to parent material/previous land use but not to slope aspect. Mean height and diameter of trees were signiﬁcantly higher in CO-AG plots than in LM-SH and GY-SH plots. Soil P and depth were the main variables explaining differences in dominant height across all 18 plots. In CO-AG plots mean height was negatively related to soil pH but positively related to soil P concentration. In LM-SH plots, mean diameter and height were negatively related to active lime concentration. This study suggests that soil P is a major determinant of holm oak performance in shallow calcareous soils and highlights the importance of conducting detailed soil studies in order to assess the viability of plantations with this species.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">García-Ruiz, José M.</style></author><author><style face="normal" font="default" size="100%">Lana-Renault, Noemí</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Hydrological and erosive consequences of farmland abandonment in Europe, with special reference to the Mediterranean region – A review</style></title><secondary-title><style face="normal" font="default" size="100%">Agriculture, Ecosystems &amp; Environment</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Bench terrace ﬁelds</style></keyword><keyword><style  face="normal" font="default" size="100%">EUROPE</style></keyword><keyword><style  face="normal" font="default" size="100%">farmland abandonment</style></keyword><keyword><style  face="normal" font="default" size="100%">Runoff generation</style></keyword><keyword><style  face="normal" font="default" size="100%">Semiarid areas</style></keyword><keyword><style  face="normal" font="default" size="100%">soil erosion</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2011</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2011///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://linkinghub.elsevier.com/retrieve/pii/S0167880911000041</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">140</style></volume><pages><style face="normal" font="default" size="100%">317 - 338</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Farmland abandonment is a major problem in parts of Europe, particularly in mountain areas and semiarid environments. In such places, farmland abandonment represents a signiﬁcant land use change from cropping to a complex of plant successions. The present study assesses the hydromorphological effects of land abandonment in Europe, and the consequences thereof with respect to water resource availability and soil erosion. The evolution of abandoned ﬁelds depends on (i) the time of abandonment; (ii) climatic conditions in the abandoned area; (iii) particular characteristics of the ﬁelds; (iv) the land management regimen following abandonment; and, (v) the role played by government policy. Throughout most of Europe, vegetation on abandoned farmland has evolved into dense forest or shrub. The expansion of vegetation explains, in part, the perceived decline in water resources, reductions in soil loss and sediment delivery, and the progressive improvement of soil characteristics. Such evolution has resulted in changing stream morphology, featuring narrowing and incision, and a decline in sedimentation level in Mediterranean reservoirs. The abandonment of bench terrace ﬁelds coincided with an increase in the occurrence of small landslides in the steps between terraces, as well as changes in the spatial organization of saturated areas. Plant colonization is slower in semiarid areas, increasing the development of soil crusts that reduce inﬁltration and increase overland ﬂow. Land policies with detailed capability are necessary to remediate the consequences of farmland abandonment in various European environments.</style></abstract><issue><style face="normal" font="default" size="100%">3-4</style></issue></record></records></xml>
