Nutrient fluxes from litterfall in mixed cropping systems of the central Amazonia.
The aim of this study was to quantify nutrient fluxes from litter fall and prunings in an agroforestry system and to determine differences associated with fertilization. The speceis used are: Bertholletia excelsa (castanha-do-Para), Bactris grasipaes (pupunha),Bixa orellana (urucu), Theobroma grandiflorum (cupuacu) and Pueraria phaseoloides as a cover crop. Annual litterfall in the agroforestry system was greater in the high fertilization treatment (1,56 t/ha) than in the low (1,42 t/ha) but the difference was not significant. Prunings were higher in the hig fertilization treatment than in the low, both from peach palm (1,33 t/ha and 1,04 t/ha) and urucu (1,79 t/ha and 1,15 t/ha).
