SOIL QUALITY UNDER AGROFORESTRY SYSTEMS AND TRADITIONAL AGRICULTURE IN THE ATLANTIC FOREST BIOME

Verrucomicrobia in Brazilian Atlantic forest soil.

The Brazilian Atlantic forest is one of the main biodiversity hot spots in the world (4). This biome stretches along the Brazilian Atlantic coast, from the state of Rio Grande do Norte to Rio Grande do Sul, with an original area of 1,233,875 km that has been reduced to less than 8% of its original cover (Fig. 1). Also included in this hot spot is the offshore archipelago of Fernando de Noronha ...

Agroforestry systems and environmental quality: introduction.

Investments in agroforestry research during the past three decades-albeit modest-have yielded significant gains in understanding the role of trees on farmlands, and the ecological and economic advantages of integrated farming systems. While early research focused mostly on farm or local levels, broader-level ecosystem services of agroforestry systems (AFS) have raised high expectations in recen...

Carbon storage in soil size fractions under two cacao agroforestry systems in Bahia, Brazil.

Shaded perennial agroforestry systems contain relatively high quantities of soil carbon (C) resulting from continuous deposition of plant residues; however, the extent to which the C is sequestered in soil will depend on the extent of physical protection of soil organic C (SOC). The main objective of this study was to characterize SOC storage in relation to soil fraction-size classes in cacao (...
