The plantation of annual and perennialc cultures permits the use of only on area for several years without cutting new areas, in case of the rubber trees until 25 years. The use of fertilizer and biological agents like VAMF, which can improve the physical and chemical soil conditions, allow the recultivation of cleared and abandoned sites with great economical returns. This reduce the 'slash and burn' agriculture, as practised by the local small holders, the environmental destruction and the rural exodus.  aagroforestry  aland use  amultiple cropping  asoil conservation  aConservação do Solo  aCultivo Multiplo  aDesenvolvimento Sustentável  aFloresta Tropical Úmida  aUso da Terra  aAgrofloresta  aAmazonas  aBrasil  aReclamation  aSustainability  aTropical rain forest1 aFELDMAN, F.1 aARAUJO, R.
