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

Biochar application to soils can regulate soil phosphorus availability: a review

Biochar, Journal Year: 2025, Volume and Issue: 7(1)

Published: Jan. 16, 2025

Abstract Phosphorus (P) is essential for basic natural processes and can limit the productivity of entire ecosystems. However, agricultural lands worldwide currently suffer from P deficiency. The application fertilizers not only poorly utilized, but also results in gradual accumulation P. Biochar, a substance produced by pyrolysis biomass under low oxygen levels, frequently used as soil amendment. It provides form that readily available plant uptake, thus addresses both short- long-term deficiencies. In this paper, we systematically reviewed relevant studies on “biochar soil” or P” published past decade (2013–2023). A synthesis reported revealed analyzing effect biochar through changes physicochemical properties microbial communities has gradually emerged prominent area research recent years. purpose study was to analyze differential effects addition availability, including clarification underlying mechanisms. showed although generally exerts positive there are differences extent based conditions. Shifting mechanisms, directly increases phosphorus (AP) content soil, indirectly influences availability via physical, chemical, biological properties. To summarize, affect different degrees direct indirect pathways. Graphical
