Summary -A field assay was carried out to evaluate the effectiveness of several methods for the afforestation of a semi-arid area of southeast Spain with Pinus halepensis. The trial was designed as a two factor factorial with four soil preparation treatments as the first factor (mechanical terracing, manual terracing, manual terracing with the addition of urban solid refuse [USR] and mechanical terracing with USR) and the addition of fresh forest soil to the planting hole as the second factor. Twentyone months after planting, the methods involving the addition of USR significantly enhanced P halepensis performance, mechanical terracing with USR being the most effective treatment in improving the survival and growth of the pines. The addition of forest soil significantly enhanced P halepensis growth in all the soil preparation treatments except in the manual terracing with USR. P halepensis growth was strongly correlated with soil moisture content (r= 0.83; P < 0.01) which was greatest in the mechanical terracing with USR treatment. Soil fertility levels, which were improved by organic amendment, were significantly correlated with seedling growth, particularly the phosphorus rates (r= 0.75; P < 0.05). The
