Biochar (BC) application has the potential to be integrated into a carbon-trading framework owing to its multiple environmental and economic benefits. Despite the increasing research attention over the past ten years, the mechanisms of BC-induced priming effects on soil organic carbon mineralization and their influencing factors have not been systematically considered. This review aims to document the recent progress in BC research by focusing on (1) how BC-induced priming effects change the soil environment, (2) the factors governing the mechanisms underlying BC amendment effects on soils, and (3) how BC amendments alter soil microbial communities and nutrient dynamics. Here, we carried out a detailed examination of the origins of different biochar, its pyrolysis conditions, and potential interactions with various factors that affect BC characteristics and mechanisms of C mineralization in primed soil. These findings clearly addressed the strong linkage between BC properties and abiotic factors that leads to change the soil microclimate, priming effects, and carbon stabilization. This review offers an overview of a fragmented body of evidence and the current state of understanding to support the application of BC in different soil environments with the aim of sustaining or improving the agricultural crop production.

生物炭 (BC) 应用具有多种环境和经济效益，因此有可能被整合到碳交易框架中。尽管近十年来研究日益受到关注，但尚未系统地考虑 BC 诱导土壤有机碳矿化的启动效应机制及其影响因素。本综述旨在记录 BC 研究的最新进展，重点关注 (1) BC 诱导的启动效应如何改变土壤环境，(2) 控制 BC 修正对土壤影响机制的因素，以及 (3) BC 如何修正改变土壤微生物群落和养分动态。在这里，我们对不同生物炭的来源、其热解条件、以及与影响底质土壤中碳矿化特征和碳矿化机制的各种因素的潜在相互作用。这些发现清楚地说明了 BC 特性与导致改变土壤微气候、启动效应和碳稳定的非生物因素之间的密切联系。本综述概述了零散的证据和当前的理解状态，以支持在不同土壤环境中应用 BC，以维持或改善农作物生产。
