This potential is affected by how biochar interacts with native soil organic carbon (SOC) and fresh organic substrates added to soil. However, only a few studies have been conducted to understand this interaction. To fill this knowledge gap, we conducted a <sup>13</sup>C-glucose labelling soil incubation for 6 months using fine-textured agricultural soil (Stagnosol) with two different biochar amounts. Biochar addition reduced the mineralization of SOC and <sup>13</sup>C-glucose and increased soil microbial biomass carbon (MBC) and microbial carbon use efficiency (CUE). The effects were found to be additive i.e., higher biochar application rate resulted in lower mineralization of SOC and <sup>13</sup>C-glucose. Additionally, soil density fractionation after 6 months revealed that most of the added biochar particles were recovered in free particulate organic matter (POM) fraction. Biochar also increased the retention of <sup>13</sup>C in free POM fraction, indicating that added <sup>13</sup>C-glucose was preserved within the biochar particles. The measurement of <sup>13</sup>C from the total amino sugar fraction extracted from the biochar particles suggested that biochar increased the microbial uptake of added <sup>13</sup>C-glucose and after they died, the dead microbial residues (necromass) accumulated inside biochar pores. Biochar also increased the proportion of occluded POM, demonstrating that increased soil occlusion following biochar addition reduced SOC mineralization. Overall, the study demonstrates the additional C sequestering potential of biochar by inducing negative priming of native SOC as well as increasing CUE, resulting in the formation and stabilization of microbial necromass.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>","PeriodicalId":8789,"journal":{"name":"Biochar","volume":"11 1","pages":""},"PeriodicalIF":12.7,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139476966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most functional microbial populations in the soil, especially the taxa involved in C degradation, nitrification, nitrate-reduction, organic P mineralization, and S cycling showed significantly positive associations with the EMF at different threshold levels, which ultimately was regulated by soil pH and nutrient availability.

This comprehensive review aims to bridge the existing knowledge gaps surrounding the mechanism and significance of nanobiochar (NBC) and carbon nanostructures in the field of antimicrobial applications. Notably, NBC, which is derived from biochar, exhibits promising potential as an environmentally-friendly substance with antimicrobial properties. Its strong adsorption capabilities enable the removal and immobilization of pathogens and pollutants from soil and water and also exhibit antimicrobial properties to combat harmful pathogens. In addition to NBC, carbon dots (CDs) and graphene oxide (GO) have also shown excellent antimicrobial properties. These carbon-based nanomaterials find applications in agriculture for phytopathogen control and post-harvest disease management, as well as in medicine for nanotheranostics and in the food industry for extending shelf life as an eco-friendly alternative to chemicals and antibiotics. However, the long-term toxicity of these nanoparticles to humans and the environment needs further investigation, considering the influence of different physiochemical characteristics on antimicrobial properties and nanotoxicity.
