In this study we present the effects of different fruit and timber tree species in a multi-strata agroforestry system on inorganic and organic P pools of a Xanthic Ferralsol. The soils were in readily available P, stressing the importance of fertilization and soil management practices for nutrient replenishment. The investigated agroforestry system consisted of cupuacu, pupunha (peach palm), castanha-do-Para (Brazil nut), urucu (annatto) and pueraria. Under canopies of the same tree species a high variation of the P contents were found especially under pupunha. The total P values of the soils in the pupuna row differed from 194 mg g-1 to 516 mg g-1. The sites under the unfertilized legume cover crop pueraria had two times higher soil P contents than those under adjacent unfertilized natural vegetation. It can be assumed that pueraria uses the P from the fertilized area under the tree crops and enrich the soil between the trees. |
