Cuiaba: UMFTc1995  ap. 163.  aInvestigações sobre espécies adequadas para o reflorestamento de áreas degradadas na Amazônia Central: In this SHIFT-PROJECT, eight native tree species of Central Amazonia (Swietenia macrophylla Krug., Carapa guianensis Aubl., Hevea brasiliensis (Willd.) Muell. Arg., Schizolobium amazonicum Ducke, Cedrela odorata L., Dipterix odorata Wylld., Hymenaea courbaril L., Tabebuia sp.), wich are accepted for timber production, are investigated with regard to their suitability for agroforestry systems. Therefore exogenous influences on tree growth and wood formation of these species are investigated on three-year-old experimental plots laid out by the EMBRAPA-CPAA/Manaus, and the Institute for Applied Botany/Hamburg University (Env.23) and additional plots with the same tree species laid out by EMBRAPA-CPAA/Manaus, with special reference to the mineral element supply of the plants. In these investigations the total tree biomass and the total mineral element content (N, P, S, K, Ca, Mg, Al, #) of the trees is quantified in one years intervals. Furthermore the intra annual variation of tree growth and wood formation is studied in relation to meteorological conditions and changes in the mineral element supply of the soil. Data of trees grown in a monoculture system (System 4, comp. ENV.23, ENV.45). From these studies more informations about the exogenous influences on tree growth and the sustainability of the mineral element supply of the trees on this forest site are expected.  aagroforestry  aenvironmental degradation  aforest trees  amultiple cropping  awood  aAdubação  aCarapa Guianensis  aCedrela Odorata  aCrescimento  aCultivo Multiplo  aDesenvolvimento Sustentável  aDeterioração do Solo  aFloresta Tropical Úmida  aHevea Brasiliensis  aHymenaea Courbaril  aMadeira  aRecuperação do Solo  aSchizolobium Amazonicum  aSwietenia Macrophylla  aAgrofloresta  aAmazonas  aBrasil  aDipterix odorata  aFertilizers application  aGrowth  aReclamation  aSustainability  aTropical rain forest1 aDUNISCH, O.1 aGASPAROTTO, L.1 aNEVES, E.
