Zusammenfassung
This paper shows the synthesis of a research programme carried out throughout 6 years about the effects of site preparation on forest soil properties, erosion and production in Pinus radiata plantations in a region of Northern Spain. For this study 58 stands located in the Basque Country were selected, all of them on slopes with gradients of between 40 and 50% and over low fertility soils, developed on argillites. Intense site preparation (removal of logging residues and litter and ploughing), increased the values of soil bulk density and decreased the organic matter contents, N, S, Ca and Mg. These labours also involved a severe soil loss by erosion during the six moth following whole-tree harvesting and site preparation. After 4 years the most perturbed soils did not improve their initial properties. These intense practices also affected the nutrition and tree growth.
