Description: Comparision of the water and nutrient fluxes in different perennial land-se systems, either monocultures or mixed cropping systems, in order to determine the resource efficiency of perennial land-se systems. They were comparision of the monocultue systems with Theobroma grandiflorum (cupuacu) or Bactris gasipaes (pupunha), polyculture systems with cupuacu, pupunh, Bixa orellana (urucum) and Bertholletia excelsa (castanha-do-Para) and primary and secondary forest sites. In the first experimental year, the equipment was installed to measure raianfall, throughfall, stemflow and soil water fluxes. These data combined with measurements of nutrient concentrations inform about the element fluxes. for this purpose, laboratory facilities were implemented to analyze anions and cations in the different land-se systems. Additionally, the nutrient and organic matter content of the soils were studied. Firt results showed that the investigated tree species differ in their effect on the water distribution and nutrient accumulation within the different cropping systems.
