Trees in a grass pasture on Atlantic Forest region

Abstract

This work aimed to evaluate several N₂-fixing and non N₂-fixing tree species, in relation to their surviving rate and growth in grass pasture, in order to form a wood-pasture system at the Atlantic Forest region. Two experiments were carried out in a grass pasture area, one with five N₂-fixing tree species (Acacia holosericea, Mimosa caesalpiniaefolia, Anadenanthera macrocarpa, Enterolobium contortisiliquum and Pseudosamanea guachapelle) and other with five non N₂-fixing (Schinus terebinthifolius, Eucalyptus grandis, Tabebuia chrysotricha, Khaya senegalensis and Senna siamea). M. caesalpiniaefolia, E. contortisiliquum, A. holosericea and E. grandis were the most recommended species for wood - pastures system mainly due to their rapid establishment rate.
