According the results, annato, cupuacu and peach palm seemed to take up more than 90% of th incorporated nitrogen fertilizer under their own canopy. However, Brazil nut took up more than 70% of the fertilized nitrogen from the fertilized areas under the canopies of the neighboring trees (peach palm: 40%, annato: 25%, cupuacu: 8%) two weeks of the fertilizer application. At the end of the rainy season, Brazil nut even took up more than 80% from underneath neighboring trees crops (peach palm: 42%, annato: 36%, cupuacu: 6%). Furthemrmore, peach palm and Brazil nut were better able than the other two trees in reducing nutrient leaching due to their deep root system.  aland use  aleaching  amultiple cropping  anitrogen  atropical rain forests  aAdubação  aBactris Gasipaes  aBertholletia Excelsa  aCastanha do Para  aCultivo Multiplo  aDesenvolvimento Sustentável  aFloresta Tropical Úmida  aLixiviação  aNitrogênio  aPupunha  aRaiz  aUso da Terra  aAgrofloresta  aAgroforesty  aAmazonas  aBixa orella  aBrasil  aFertilizers application  aManaus  aSustainability  aUrucu1 aLEHMANN, J.1 aKAISER, K.1 aTEIXEIRA, W.
