Description:	Study on the fertilizer effects on P, K, Ca and Mg contents in mixed tred cropping system (castanha-do-Para, pupunha, cupuacu, pueraria). Fertilizers at four different levels (30%, 100%, 100%+P and 30%-N-lime) of the recommended fertilization, Embrapa Amazonia Ocidental, Manaus-AM, Brasil). The high soil nutrient contents under pupunha indicated that this species does not need the large amounts of fertilizers applied. For urucu, the P and K fertilization could be reduced. Generally, the species effect was more clearly visible below 15 cm depth, whereas the effect of fertilizationdominated the nutrient differences at the topsoil.
