Biochar application in remediating salt-affected soil to achieve carbon neutrality and abate climate change

Biochar, Год журнала: 2023, Номер 5(1)

Опубликована: Июль 21, 2023

Abstract Salt-affected soils urgently need to be remediated achieve the goals of carbon neutrality and food security. Limited reviews are available on biochar performance in remediating salt-affected context climate change mitigation. This work summarized two pathways during using biochars, i.e., production from sustainable feedstock thermal technologies, application for promoting plant productivity mitigating greenhouse gas (GHG) emission. Converting biomass wastes into biochars can reduce GHG emission promote dioxide removal (CDR), collection halophyte as feedstocks, development poly-generation systems with or negativity could promising strategies. Biochar effectively improve growth soils, showing that grand mean response was 29.3%, via improving physicochemical characteristics, shifting microbial communities, enhancing halotolerance. Moreover, mitigate inducing negative priming effect, soil properties, changing communities associated nitrogen cycle, direct adsorption GHG. However, also may pose effects because stress toxic compounds free radicals, deterioration properties. The promoted is mainly ascribed positive provision labile inorganic fractions substrates. Finally, this review pointed out gaps current studies future perspectives. Particularly, “carbon neutral” negative” system, balancing relationship effectiveness functionality its environmental risks costs, designing biochar-based adsorbents would important directions abate change.

Biochar as a tool for the improvement of soil and environment

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

Опубликована: Дек. 18, 2023

Biochar is a versatile and sustainable tool for agricultural environmental remediation due to its unique physicochemical properties in terms of soil fertility, nutrient retention, water holding capacity. As stable carbon-rich material, biochar promotes plant growth increases crop yields by enhancing microbial activity. It can also be used as sorbent removing pollutants such heavy metals, organic contaminants, nutrients from systems. However, the utility ecological impact affected combined effects many variables. This paper discusses application on potential mitigate various challenges composition, augmenting accessibility, part efforts promote agriculture based recent findings. These findings are expected improve farming while contributing mitigation climate change diverse routes (e.g., sequestering atmospheric carbon, improving quality, reducing greenhouse gas emissions). offers promising opportunity help harness power pave way more resilient future.

Identifying biochar production variables to maximise exchangeable cations and increase nutrient availability in soils

Journal of Cleaner Production, Год журнала: 2024, Номер 446, С. 141454 - 141454

Опубликована: Фев. 24, 2024

Biochar is a product of the thermal treatment sustainably sourced organics or waste biomass, which enhances nutrient availability and exchangeable cations after soil application. feedstock one primary factors influencing in biochar soil-biochar mix. However, this influence not satisfactorily understood due to contrasting data among literature for cation exchange capacity (CEC) lack standard analysis methods CEC mixtures. Therefore, research was conducted assess mixes, where measured as (1) sum base (Na+, K+, Mg 2+, Ca2+) displaced by ammonium acetate (CEC-BC) (2) NH4+ potassium chloride (CEC-NH4+). For first time, we have evaluated CEC-BC CEC-NH4+ 21 different samples using modified method. We then used 12 representative biochars with 3 types (2% w/w biochar) provided insights on relative changes individual cations. Some previous studies indicated relationship between surface area degree additivity resulting mixes. our study demonstrates an absence these correlations products. found that prepared from mixed garden wastes can increase K+ Ca2+ loamy sandy soils mitigate potential sodicity problems soils. clayey may need specific purpose increasing Our results revealed hardwood retain deliver it acting sink source nutrients.
