Abstract

The thesis project, funded by FAPESP, belongs to the experimental network CIFOR (Center for International Forestry Research) based in Jacarta, Indonesia, and has as one of its research line the study of sustainable management of planted forests in tropical and subtropical environments regions about the intensity of tillage systems and management of these forest harvest residues. Currently, the network includes 16 local experiments with typical commercial forestry plantations (10 with Eucalyptus, 4 with Acacia and 2 with Pinus) in 8 countries (Australia, Brazil, Congo, China, India, Indonesia, South Africa and Vietnam) which represent forest plantations on a wide range of biophysical environments, species with potential production and forest management strategies. The motivation for the proposal of scholarship research (BEPE) is due to the fact that this is developed at the research center Australian Commonwealth Scientific and Industrial Research Organisation - CSIRO, specifically in unit located in Hobart, Tasmania, CSIRO Ecosystem Sciences where the experimental network was conceived. As main aim we have: i) acknowledgment, collection and assessment of data from an experiment set in Australia, which also belongs to the experimental network CIFOR ii) use the model CABALA (Carbon Balance) for modeling the data already collected in the experiment of Brazil as well as data that will be collected in the experiment of Australia. The modeling will be developed with data from nitrogen mineralisation that have been collected in the experiment with E. grandis in Brazil. Samples for determination of nitrogen mineralization in the experiment with E. globulus in Australia will be collected on site and subsequently validated by model CABALA. (AU)
