| Summary, etc |
The influence of trees on soil properties should be a determining factor in the choice of species for tree-crop combinations or for tree plantations in the humid tropics. However, information of this kind is scarce, particularly for native specis. Soil fertility parameters were compared under six tree year-old secondary forest. The site is located at the La Selva Biological Station fo the Organization for Tropical Studies, in the Atlantic humid lowlands of Costa Rica, Central America. Soil extractable Ca, Mg, K,P,Fe,Mn, Cu and Zn, the pH, exchangeable acidity, organic matter and total N were measured under Stryphnodendron excelsum, Dalbergia tucurensis, Dipteryx panamensis, Vochysia hondurensis, Vochysia ferruginea and Tebebuia rosea. Al species are native and of economic value for the timber industry. Higher soil N and levels of organic matter were found in the tree plantation than under grass, with values close to hose in the secondary forest. Within the tree plantation, the highest values for soil organic matter, total N,Ca, and P were found under V.ferruginea. There was an apparent trend of higher soil nitrate content under S.excelsum and D. tucurensis, both leguminous nitrogen-fixing species. The results will be used to make recommendations on species for plantations or for agroforestry, emphasizing the potential positive effects on soil properties for recovery of degraded pastures in the region |
