The investigated soil showed an unusual behavior: the hydraulic conductivty was high close to and at saturation as it is commonly found in sady soils; however, at high soil water suction, it can retain large amounts of water which is a typical characteristics for clayey soils. This phenomenon may explained to the particle size distribuition (predominatly clay) and its strong aggregation. The sustainability of this soil is related with the stability of its aggregation, therefore the flocculation index may be a good parameter to evaluate its physical stability. aagroforestry afruit trees aland use amultiple cropping asoil conservation asoil water balance atropical rain forests aÁrvore Frutífera aBalanço Hídrico aConservação do Solo aCultivo Multiplo aDesenvolvimento Sustentável aFísica do Solo aFloresta Tropical Úmida aRecuperação do Solo aRelação Solo-Água aUso da Terra aAgrofloresta aAmazonas aBrasil aManaus aReclamation aSoil chemicophysical properties aSustainability1 aHUWE, B.1 aSCHROTH, G.
