Soil nutrient leaching in mixed tree cropping systems in the central Amazon.
Studies on the leaching losses of applied 15N tagged fertilizer during one rainy season, in the central Amazonia (Manaus-AM, Brasil). TDR, tensiometers and suction cups were installed under cupuacu, pupunha (peach palm), castanha-do-Para (Brazil nut) and urucu (annatto) in a mult-strata agroforestry system. The trees affected leaching losses of applied N to a different extend, and pupunha and urucu were better able to do so than the other investigated species. However, losses of applied fertilizer N can not entirely be prevented considering the extremely rapid soil water percolation under the studied humid tropical conditions and the highly permeable soil.
