Biochar has been widely recognized for its potential to increase carbon sequestration and mitigate climate change. This potential is affected by how biochar interacts with native soil organic carbon and fresh organic substrates added to soil. However, only a few studies have been conducted to understand this interaction. To fill this knowledge gap, the authors conducted a 13C-glucose labelling soil incubation for 6 months using fine-textured agricultural soil (Stagnosol) with two different biochar amounts.
