“Reactive Mineral Sink” drives soil organic matter dynamics and stabilization

npj Materials Sustainability, Journal Year: 2023, Volume and Issue: 1(1)

Published: Nov. 27, 2023

Abstract Reactive primary and secondary minerals play a critical role in the transformation stabilization of organic matter (OM) soil, aspect that has been largely overlooked existing literature. In this regard, we propose new model known as “reactive mineral sink” (RMS) to illustrate three mechanisms through which these drive bioprocessing, transformation, transport OM soil. Firstly, from biological perspective, reactive influence enzymatic microbial processing binding proteins or influencing structure communities. Secondly, chemical standpoint, have capacity adsorb and/or coprecipitate with it, leading more diverse distribution This distribution, turn, triggers catalysis redox reactions. Thirdly, on physical level, substantial impact soil architecture, aggregate dynamics, porosity development, hydrological processes. These changes then affect transport, reprocessing OM. The RMS provides conceptual framework underscores fundamental driving dynamics carbon (C) sequestration natural Furthermore, it promotes restoration biogeochemical processes ecological resilience. We advocate for implementation strategies based enhance C soils purposes rejuvenating health mitigating CO 2 emission.

Dosage- and site-dependent retention of black carbon and polycyclic aromatic hydrocarbons in farmland soils via long-term biochar addition

Carbon Research, Journal Year: 2024, Volume and Issue: 3(1)

Published: Feb. 8, 2024

Abstract Biochar, a soil conditioner containing significant amounts of polycyclic aromatic hydrocarbons (PAHs), has gained widespread popularity in agricultural practices due to its advantages improving fertility and carbon sequestration. While biochar may increase black (BC) PAH contents, the quantitative accumulation BC PAHs different environments under varying addition dosages remains poorly understood. Here, we investigated content composition (evaluated using benzene polycarboxylic acids, BPCAs) soils treated with from two long-term experimental farmlands Ningxia (5-year) Shandong (7- 11-year), China. Results showed that increasing cumulative dosage caused elevated contents PAHs, accompanied by decreases their retention efficiencies. Contrasting was observed between sites, site characterized higher efficiencies BPCAs lower possibly owing temperature, more sandy texture, less irrigation, sunlight intensity. Despite both originating sharing similar condensed structures, there no correlation indicating distinct behaviors fates these compounds. These findings emphasize importance optimizing considering site-specific environmental factors for effective sequestration through application. Graphical
