Degradation and Restoration of Anthrosols in the Amazonia Under Contrasting Agricultural Practices: Evidence From the Assessment of Soil Physical Quality and Carbon and Nitrogen Stocks

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT This study was conducted to assess the impact of different agricultural practices on the physical quality and the carbon and nitrogen stocks of anthropogenic soils used by smallholder farmers in Central Amazonia, Brazil. Undisturbed and disturbed soil samples were collected at three depths (0–0.10 m, 0.10–0.20 m, and 0.20–0.30 m), with five ...
