Descripción:	Experimental polycylture systems have been established in central Amazonia in order to test their suitability for sustainable land use. comparative studies on vegetation, on soil microbiological aspects and the quantification of mineral nutrients allow first approaches to understand regulating factor of the agroforestry systems. The leguminous plant Pueraria phaseoloides reveals to be a suitable management factor in plant polycultures, but it turned out to act also as competitor for mineral nutrients. Up to eight months after slash and burn treatment the soil microbial titer for nodulation of pueraria is very low, the morphologically intact spores of arbuscular micorrhizal fungi of the topsoil are dead. The naturally occuring leguminous plants of the primary and secondary forest were listed. Their potential as factor for polyculture systems has so far not been evaluated.
