TDR, tensiometers and suction cups were installed under cupuacu, pupunha (peach palm), castanha-do-Para (Brazil nut) and urucu (annatto) in a mult-strata agroforestry system. The trees affected leaching losses of applied N to a different extend, and pupunha and urucu were better able to do so than the other investigated species. However, losses of applied fertilizer N can not entirely be prevented considering the extremely rapid soil water percolation under the studied humid tropical conditions and the highly permeable soil.  aleaching  alegumes  anutrients  asoil conservation  asoil fertility  asoil water  atropical rain forests  aÁgua do Solo  aBactris Gasipaes  aBertholletia Excelsa  aBixa Orellana  aCastanha do Para  aCobertura do Solo  aConservação do Solo  aCupuaçu  aFísica do Solo  aFloresta Tropical Úmida  aLeguminosa  aLixiviação  aNitrogênio  aNutriente  aPueraria Phaseoloides  aPupunha  aRelação Água-Planta  aTensiômetro  aAmazonas  aBrasil  aCover plants  aManaus  aPlant water relations  aTheobrama grandiflorum  aUrucu1 aLEHMANN, J.1 aTEIXEIRA, W.1 aHUWE, B.1 aZECH, W.
