ABSTRACT Due to large-scale wetland reclamation, the typical wetland had been conversed to different wetland use types (upland field, paddy field, and artificial forest) in the Sanjiang Plain. However, there are scarce data regarding soil aggregates and active organic carbons during land-use transition. Here, soil aggregates and the changes in content and storage of active organic carbon [total organic carbon (TOC), dissolved organic carbon (DOC), microbial biomass carbon (MBC), and readily oxidized carbon (ROC)] were studied under three land-uses reclaiming […]

This study was carried out in the Western region of Minas Gerais, Brazil to evaluate the morphological changes in a Yellow-Red Latosol, after a conversion of a 20 year old Brachiaria decumbens pasture, under intensive pasture systems; a pure Brachiaria decumbens and an association of this grass with the legume Stylosanthes guianensis. Through morphological and physical characterization, it could be concluded that: (a) there were structural obstructions to radicular development in the old pasture soil; (b) the soil macrofauna played […]
