Programa and abstracts... Hamburg: Universityc2000  ap. 226.  aWe studied soil fertility and plant nutrition in multi-strata agroforestry systems with several perennial crop species at four fertilization levels to obtain information on growth-limiting nutrients and to develop optimum sampling schemes for foliar analysis for the different species: peach palm (pupunha), cupuacu, Brazil nut (castanha-do-Para), annatto (urucu) and the cover crop Pueraria phaseoloides.  aagroforestry  amultiple cropping  aplant nutrition  asoil conservation  atropical rain forests  aAdubação  aBactris Gasipaes  aConservação do Solo  aCultivo Multiplo  aCupuaçu  aFloresta Tropical Úmida  aNutrição  aPupunha  aTheobroma Grandiflorum  aAgrofloresta  aAmazonas  aBrasil  aFertilizers application  aManaus1 aSCHROTH, G.1 aMACEDO, J.
