Conteúdo:	Eucalyptus ssp. (eucalyptus) is commonly used in integrated crop-livestock-forestry and livestock-forestry systems. Acacia mangium (acacia) grows as fast as eucalyptus in tropical conditions and is capable of fixing N2 from the atmosphere. Both species differ in terms of litter quality: eucalyptus has a higher C:N ratio, lower N:P and C:P ratios, and lower lignin and cellulose contents compared to acacia. This study evaluates how the residues (litter) of each species affect the C and N contents (in g kg-1) in particulate organic matter (POM) and mineral-associated organic matter (MAOM) when nutrients (N, P, S) that intensify the humification process are applied to the soil under two different levels. Our hypothesis is that the sequestration of C-rich litter into the fine fraction (MAOM) could be improved by adding supplementary nutrients.
