To rehabilitate the productivity, C sequestration, and biodiversity of the huge expanses of low biomass, abandoned pastures in the central Amazon of Brazil, we have designed and are testing four agroforestry multistrata systems. A key goal was to optimize both biological productivity and economic returns, while minimizing nutrient losses through a combination of biological and modest chemical inputs. A key specification of the design was to optimize both biological productivity and economic returns, while minimizing nutrient losses through a combination of biological and modest chemical inputs. We identified local agroforestry systems and the preferred food and fruit crops for home consumption and sale to local markets. Local researchers identified the key soil and crop production constraints.
P is very low.
Not all of the above specifications need appear in a single system. A mosaic of three to five systems containing these specifications in various combinations is likely to be both productive and resilient to biological, environmental and economic shocks. The dominant vegetation at the site is moist, evergreen forest. Soil Depth ECEC Base Sat. The dominant vegetation at the site is moist, evergreen forest.
