dc.descriptionOne aim of the SHIFT project "Secondary Forests and Fallow Vegetation in the Agricultural Landscape of the Eastern Amazon Region (ENV 25/2)” is to shorten the fallow period by planting fast-growing leguminous trees. Therefore, the screening and identification of suitable leguminous trees for improved fallows in term of biological N2-fixation (BNF) was an important objective of the present work. Previous studies in the main project area showed that an improved fallow system with Acacia mangium planted at a spacing of 1 m x 1 m accumulated about 56 t ha-1 aboveground biomass within two years, which is about twice as much as the above-ground biomass production by Clitorea racemosa (27 t ha-1) at a spacing of 2 m x 2 m or by the spontaneous natural fallow (24 t ha-1).
