Respuesta hidrológica y erosiva de suelos con enmiendas en condiciones climáticas mediterráneas

Abstract

This study deals with the impact of some amendments on runoff and soil loss under dry Mediterranean climate in afforestation sites. Four organic amendments under the same rainfall regime were studied over a two year period: i) straw mulching (SM); ii) mulch with chipped branches of Aleppo Pine (Pinus halepensis L.) (PM); iii) sheep manure compost (SH); iv) sewage sludge (RU). The aim of the study was to evaluate the role played by different soil organic amendments in runoff generation and soil loss from closed and afforested plots. The results denote that PM, SM and RU resulted very effective methods to control runoff and sediments. Moreover, the polymers were effective when I30 was low. However, this effect disappeared as rainfall intensity increased.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech
