Conteúdo:	Aim of the study was to investigate the nitrogen dynamics and the fate of applied nitrogen fertilizer in the soil-plant system of a mixed cropping system consisting of peach palm, cupuacu, urucu, and Brazil nut, in the Manaus-AM (Brasil). 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.
