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

Contaminant containment for sustainable remediation of persistent contaminants in soil and groundwater

Journal of Hazardous Materials, Год журнала: 2023, Номер 455, С. 131575 - 131575

Contaminant containment measures are often necessary to prevent or minimize offsite movement of contaminated materials for disposal other purposes when they can be buried left in place due extensive subsurface contamination. These include physical, chemical, and biological technologies such as impermeable permeable barriers, stabilization solidification, phytostabilization. is advantageous because it stop contaminant plumes from migrating further allow pollutant reduction at sites where the source inaccessible cannot removed. Moreover, unlike options, do not require excavation substrates. However, regular inspections monitor mobilization migration. This review critically evaluates sources persistent contaminants, different approaches remediation, various physical-chemical-biological processes containment. Additionally, provides case studies operations under real simulated field conditions. In summary, essential preventing contamination reducing risks public health environment. While periodic monitoring necessary, benefits make a valuable remediation option methods feasible.

Biochar-Soil-Plant interactions: A cross talk for sustainable agriculture under changing climate

Frontiers in Environmental Science, Год журнала: 2023, Номер 11

Опубликована: Фев. 14, 2023

Biochars provide several agricultural and environmental benefits, such as soil health improvement, better crop growth yield, carbon sequestration, decreasing greenhouse gas (GHGs) emissions, regulation of nutrient dynamics. This review highlights the role biochar in transforming soil’s physiochemical biological properties, their impact on improving seed germination seedling growth, altering physiological attributes, enhancing resistance against biotic abiotic stresses, productivity, curtailing GHGs, controlling leaching losses. However, type feedstock used, pyrolysis temperature, application rate method, species largely influence performance under different conditions. Application biochars at low rates help to promote growth. Biochar modified microbial processes rhizosphere increased mineralization enhanced availability for plant uptake. Hence, diseases, reduced heavy metals improved resilience stressors. By providing a comprehensive analysis about variable impacts physicochemical development productivity mitigating problems, this is quite valuable developing an efficient specific with desired functionalities. It could be helpful ensuring food security management environment. Furthermore, identifies knowledge gaps suggests future outlooks commercialization applications large-scale.
