ABSTRACT Integration of systems with pastures, using silvopastoral systems, can increase soil carbon levels, optimize land use, improve the quality and productivity of agricultural products, and promote the conservation of environmental resources. This study aimed to evaluate the influence of management practices of marandu grass at eucalyptus shading levels in a silvopastoral systems, on organic carbon and nitrogen stocks, and soil chemical properties in the Brazilian Cerrado. Environments with different light availability in the plots (SPS 55-60, SPS 50-55, SPS […]

There is evidence that pastures formed by some species of the genus Brachiaria could be benefited by the biological nitrogen fixation process (BNF), which would give these pastures a higher longevity. Among the diazotrophic bacteria found in association with these forage grasses, the species Azospirillum amazonense is most outstanding. This study aimed to verify the influence of the Brachiaria species, pasture management, and seasonal variations on the A. amazonense populations associated to the plant roots. Different pastures (B. humidicola, B. […]
