Description: The objective of this study was to analyse the biomass production and nutrition of pueraria as a cover crop grown in three different agroforestry systems (System 1: cupuacu, pupunha (peach palm), and seringueira (rubber tree); System 2: cupuacu, pupunha and urucu (annatto); System 3: cupuacu, seringueira, coco and citrus) at two levels of fertilisation, and its potential to contribute to the N stocks of the cropping system by biological N2 fixation, in Manaus-AM (Brasil). The larger nutrient uptake and return through litter indicated a rapid nutrient cycling at the plant-topsoil interface thus reducing leaching and keeping nutrients in a vailable form. The considerable amount of biologically fixed N2 was a relevant and important addition to the N pool of the cropping systems.
