Descripción

Mixed plantations of Eucalyptus spp. with leguminous trees can increase soil carbon accumulation, but results may vary according to structure (% of leguminous trees and spacing), aboveground growth potential, land-use history due to belowground interactions, and plantation age. Most studies with mixed plantations in Brazil have been carried out in the 1st or 2nd rotations. This study, however, aims to explore the long-term effects of the presence of Acacia mangium (acacia), a nitrogen-fixing species, on C and N stocks in a mixed plantation with Eucalyptus grandis (eucalyptus).
