DECOMPOSITION, DYNAMIC OF INORGANIC ELEMENTS AND MICROBIAL COLONIZATION OF ARARIBÁ (Centrolobium tomentosum Guill. ex Benth) LEAVES ON LATOSOLS OF BRAZILIAN ATLANTIC FOREST

Leguminous trees are being planted in order to establish restoration units in the Brazilian Atlantic forest ecosystem. The success of the establishment depends on the growth, productivity of plants and litter decomposition rates. The objective of this study was to investigate the decomposition of ar...

The objective of this study was to investigate the decomposition of araribá (Centrolobium tomentosum Guill. Ex Benth) leaves, at two sites. Site 1 was an experimental plantation of the native species C. tomentosum, which was inoculated with rhizobia plus mycorrhizal fungi, and Site 2 was a eucalyptus (Eucalyptus grandis W.
