Does Tree Diversity Affect Soil Fertility? Initial Findings from Fallow Systems in West Kalimantan

Intensification of management to achieve more efficient and productive fallows in the uplands of Southeast Asia is likely to alter the species composition and structure of the tree community in traditional fallows. Consequent changes in nutrient cycling may compromise the sustainability of these systems, as well as the future productivity of the land. Therefore, understanding the influence of the tree community on nutrient dynamics is critical to formulating long-term solutions to fallow degradation, especially in systems with low potential inputs of capital and labor.
