AbstractThe use of agroforestry systems is one way to minimize soil degradation caused by slash and burn agriculture. This research investigated agroforestry systems models for areas of low fertility soils. The experimental area is located in the state of Rondônia, western of Brazilian Amazon region, in a clayey oxisol. The following treatments were tested in the experiment: 1) brazil nut (Bertholletia excelsa) x cupuaçu (Theobroma grandiflorum); 2) Cordia alliodora x cupuaçu; 3) peach palm (Bactris gasipaes) x cupuaçu; 4) brazil nut; 5) cordia and 6) peach palm. Fruit production, timber growth, exportation, and immobilization of nutrients, and nutrient cycling were determined. From the results of this study, brazil nut appears as a good option to associate with cupuaçu in low fertility soils; chemical fertilization must be considered when associating cordia wood or peach palm with cupuaçu; brazil nut x cupuaçu system litter production represented a nutrient source for cupuaçu fruit production; association did not affected Brazil nut aerial biomass, while cordia wood was influenced.
