摘要

The evolution of pasture production and tree growth will determine the adequate evolution of the stocking rate in a recently established silvopastoral system. This study aims to evaluate the effect of lime and sewage sludge doses on soil pH, tree growth (diameter at breast height DBH and height) and pasture production in different positions (beneath and beyond the tree and N, W, E, and S) after six years of the experiment. Soil pH, tree height, and DBH were improved when no lime and a high dose of sewage sludge were applied, which limited pasture production. The same effect on soil and tree variables was found in the lime and intermediate sewage sludge dose treatments, but in this case this improvement increased pasture production and may have beendue to the greater effect of the sun on ecological variables (temperature and humidity), which allowed the incorporation of the remains of the leaves of the tree and pasture into the soil. The position of the pasture affected the effect of the treatmentson pasture production, being more important in northern and western positions, where the effect of the sun on temperature and humidity is more important.
