Última Carbon sequestration in clay and silt fractions of Brazilian soils under conventional and no-tillage systems Scientia Agricola Reis,Cecília Estima Sacramento dos; Dick,Deborah Pinheiro; Caldas,Jennifer da Silva; Bayer,Cimélio. The capacity of soils to sequestrate carbon (C) is mainly related to the formation of organo-mineral complexes. In this study, we investigated the influence of soil management systems on the C retention capacity of soil with an emphasis on the silt and clay fractions of two subtropical soils with different mineralogy and climate. Samples from a Humic Hapludox and a Rhodic Hapludox, clayey soils cultivated for approximately 30 years under no-tillage (NT) and conventional tillage (CT) were collected from six layers distributed within 100-cm soil depth from each site and from an adjacent native forest. After the removal of particulate organic matter (POM), the suspension (<53 µm) was sonicated, the silt and clay fractions were separated in accordance with...
