Description:	Studies on the effect of fertilization on soil acidity and pH dynamics in a mixed tree croping system with castanha-do-Para (Brazil nut), cupuacu, pupunha (peach palm), urucu (annatto) and pueraria.Fertilizer at four different levels (30%, 100%+P and 30%-N-lime, of the recommended fertilization, Embrapa Amazonia Ocidental, Manaus-AM, Brasil) was applied. Fertilization at a level of 30%-N-lime produced highest acidity compared to the other levels of fertilization. The effect of fertilization on soil acidity was restricted to a depth of 0 cm-5 cm. Pueraria and urucu presented the highest acidity at all. depths. The effec of soil pH was opposite to acidity, highest for cupuacu and pupunha and lowest for urucu at all depths.
