SUMMARY:

Shifting agriculture contributes to the supply of local businesses in the Amazonia and, therefore, guarantees the subsistence and income of small producers. However, the activity is responsible for the emission of greenhouse gases due to the use of fire to clean the area and consequent interruption of biogeochemical cycles. This activity intensifies the expansion of secondary forests, which currently corresponds to 280 million hectares worldwide. Therefore, understanding the factors that imply the dynamics of these ecosystems is essential to establish conservation and restoration strategies, especially in the Amazonia. The MANFLORA project, for example, after 8 years of water and nutrient management (1999 - 2007) found effects of irrigation on decomposition rates, in addition to the loss of nutrient removal via litter for root biomass. However, little is known about the possible long-term effects of resource management. Thus, after more than a decade of the conclusion of the research, the objective of this dissertation will be to evaluate, through indicators, the residual effects of the manipulation of water and nutrients in a secondary tropical forest.
