ABSTRACT
Conservation of biodiversity and mitigation of global warming are two major environmental challenges today. In the context of climate change and the global carbon cycle, the relationship between plant biodiversity and soil organic carbon sequestration has become a subject of considerable scientific interest. Promoting agroforestry is one option many perceive as a major opportunity to deal with problems related to land-use and CO2-induced global warming. The agroforestry system has today become an established approach to integrated land management, not only for renewable resource production, but also for ecological considerations. In an undisturbed tree system, if nutrients supply is not met by the biological cycling, the import of nutrients from atmosphere is taken care of by soil microorganisms.
