Conteúdo:	Presentation of the effects of different fruit and timber tree species in a multi-strata agroforestry systems in comparison to secondary vegetation and primary forest sites on inorganic and organic P pools of a Ferralsols in the Amazon basin. The S pools were also assessed, but could not be presented here due to the lenght of this contribution. Conclusion: The modified Hedley procedure proved to be extremely useful for the studied soil type to demonstrate the highly contrasting P dynamics of the experimental sites. The different tree species exhibited a pronuounced and relevant effect on P properties in the multi-strata agroforestry system. These strongly contrasting effects have to be considered when designing multi-strata agroforestry systems and may help to improve the efficiency of nutrient cycling.
