In this study the biomass product and the mineral element supply of selected useful tropical plants will be determined. Parallel to it the availability of nutrient element in the soil will be analyzed. These experiments may allow an evaluation, in which way a sustainable growth of the suggested plant system under the prevailing site conditions is possible.  abiomass  aforest trees  aminerals  aBactris Gasipaes  aBiomassa  aBixa Orellana  aEssência Florestal  aFloresta Tropical Úmida  aMineral  aProdução  aSchizolobium Amazonicum  aSwietenia Macrophylla  aTheobroma Grandiflorum  aAmazonas  aBrasil  aProduction  aTropical rain forest  aUseful tropical plants1 aLIEBEREI, R.1 aPREISINGER, H.1 aBAUCH, J.1 aGASPAROTTO, L.
