Abstract:
Biochar, the carbon-rich material produced from biomass pyrolysis, has garnered significant attention and research interest owing to its myriad of potential benefits for soil enhancement. These benefits range from increasing soil carbon storage, boosting soil fertility, to transforming and fixing pollutants in soil, all of which serve to ameliorate the overall soil environment. The impact of these improvements extends to the metabolic activities and community structure of soil microorganisms, either directly or indirectly, creating ripple effects on soil health. This paper embarks on a thorough review of biochar's effects on various soil aspects. These include the soil's physicochemical properties, such as its structure, composition, and reaction properties, and how biochar can influence these to improve the soil environment. It also explores how biochar affects enzyme activities in the soil that are crucial for various biochemical processes, as well as nutrients vital for plant growth and development. Importantly, the ability of biochar to interact with contaminants, rendering them harmless or less toxic, is examined, alongside an investigation into the related microbial activities that are influenced by these changes. This work also aims to summarise the potential mechanisms of interaction between biochar and microorganisms, providing a clearer understanding of how biochar influences the soil microbiome. It discusses the potential risks associated with biochar use, such as the release of harmful substances or unintended shifts in microbial communities, emphasizing the importance of a balanced view towards biochar application. Overall, the aim of this study is to lay a robust theoretical groundwork for future research in this field, contributing towards a better understanding and utilisation of biochar for soil enhancement and sustainable agriculture.
