Mixed plantations of Eucalyptus spp. with nitrogen fixing trees may accumulate more carbon in the soil than their monoculture, but this is affected by some factors including the percentage and spacing of leguminous trees, aboveground growth potential, forest management, rotation and the land-use history. This study aims to explore the long-term effects (third rotation) of intercropping Acacia Mangium – a leguminous tree species that fixes N2 – with E. grandis on soil C and N stocks in a sandy soil (Itatinga Municipality, SP).
