The speceis used are: Bertholletia excelsa (castanha-do-Para), Bactris grasipaes (pupunha),Bixa orellana (urucu), Theobroma grandiflorum (cupuacu) and Pueraria phaseoloides as a cover crop. Annual litterfall in the agroforestry system was greater in the high fertilization treatment (1,56 t/ha) than in the low (1,42 t/ha) but the difference was not significant. Prunings were higher in the hig fertilization treatment than in the low, both from peach palm (1,33 t/ha and 1,04 t/ha) and urucu (1,79 t/ha and 1,15 t/ha).  aagroforestry  alegumes  amultiple cropping  anutrient transport  asoil conservation  asoil fertility  aAdubação  aBactris Gasipaes  aBertholletia Excelsa  aBixa Orellana  aCastanha do Para  aCobertura do Solo  aConservação do Solo  aCultivo Multiplo  aFertilidade do Solo  aFloresta Tropical Úmida  aLeguminosa  aPueraria Phaseoloides  aPupunha  aSerapilheira  aTheobroma Grandiflorum  aTransporte de Nutriente  aAgrofloresta  aAmazonas  aBrasil  aCover plants  aFertilizers application  aLitter plants  aManaus  aTropical rain forest  aUrucu1 aBERNHARD-REVERSAT, F.1 aLUIZAO, J.
