Conteúdo: | The land use systems investigated were installed by ENV-23 inplots of 32m by 48m in a randomized complete block design with five blocks. Two of the blocks were later excluded by ENV-45 due to differing growth. ENV-45 investigates two monoculture systems (with perennial species cupuacu and pupunha, respectively (both fertilized at 100% of the dose recommended by Embrapa for the single trees of the respective species) and one agroforestry system with Brazilian nut, cupuacu, pupunha, and urucum as perennial species. This AF system was investigated at twi fertukuzer keveks 100% and 30%. Cassava was cropped in the AF-System in 1993 only and is not considered in this study. Puerearia was cover crop in all systems, although sparse in the pupunha monoculture; secondary growth was regularly teimmed in the plots. The primary forest of the site was mechanically cleared for the first time in 1980. The row rubber-experiments which preceded the present SHIFT-experiment were abandoned in 1986. Soil tupe of the non-inundated site is an Oxisol with almost 90% low activity clay..
