Carbon Sequestration Strategies in Soil Using Biochar: Advances, Challenges, and Opportunities

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(31), P. 11357 - 11372

Published: July 26, 2023

Biochar, a carbon (C)-rich material obtained from the thermochemical conversion of biomass under oxygen-limited environments, has been proposed as one most promising materials for C sequestration and climate mitigation in soil. The contribution biochar hinges not only on its fused aromatic structure but also abiotic biotic reactions with soil components across entire life cycle environment. For instance, minerals microorganisms can deeply participate mineralization or complexation labile (soluble easily decomposable) even recalcitrant fractions biochar, thereby profoundly affecting cycling Here we identify five key issues closely related to application review outstanding advances. Specifically, terms use pyrochar, hydrochar, stability soil, effect flux speciation changes emission nitrogen-containing greenhouse gases induced by production application, barriers are expounded. By elaborating these critical issues, discuss challenges knowledge gaps that hinder our understanding provide outlooks future research directions. We suggest combining mechanistic biochar-to-soil interactions long-term field studies, while considering influence multiple factors processes, is essential bridge gaps. Further, standards should be widely implemented, threshold values urgently developed. Also needed comprehensive prospective assessments restricted account contributions contamination remediation, quality improvement, vegetation accurately reflect total benefits
