Biochar-Based Granular Fertilizers with Agro-Industrial Binders Enhance Enzymatic Activity and Nutrient Cycling in Tropical Oxisols

José Mendes dos Santos Júnior, Luiz Arnaldo Fernandes, Fernando Colen, Leidivan Almeida Frazão e Rodinei Facco Pegoraro Abstract Abstract The low fertility of tropical Oxisols challenges sustainable agriculture. While biochar-based granular fertilizers (BBGFs) offer a solution, the influence of different organic binders is unclear. This study investigated how BBGFs formulated with bio-oil (BO), pyroligneous extract […]
