ABSTRACT Improvement of fallow vegetation can have a positive impact on the productivity of slash-and-mulch systems in eastern Amazonia. Phosphorus fertilization can increase biomass and nutrient stocks in the fallow phase, thereby improving nutrient cycling and crop productivity. Here, we compared biomass and nutrient stocks under three fallow management strategies: (1) natural fallow (regrowth vegetation) - NF; (2) NF vegetation improved with leguminous trees (Sclerolobium paniculatum Vogel and Inga edulis Mart.) - IF; and (3) NF vegetation improved with leguminous trees plus phosphorus fertilization - IF+P. We quantified above- and belowground biomass and N, P, K, Ca, and Mg stocks after 23 months of fallow. The IF+P increased aboveground (leaf + branch... |
