Biochar as a sustainable tool for improving the health of salt-affected soils

Soil & Environmental Health, Journal Year: 2023, Volume and Issue: 1(3), P. 100033 - 100033

Published: July 20, 2023

Salt-affected soil has become one of the major threats to health. However, evaluation biochar amendment effects and underlying mechanisms on physical, chemical, biological indicators used for assessing health salt-affected is lacking. This review summarized performance in improving soils. Biochar addition significantly improved physico-chemical properties by enhancing aggregate stability (15.0–34.9%), porosity (8.9%), water retention capacity (7.8–18.2%), increasing cation exchange (21.1%), organic carbon (63.1%), nutrient availability (31.3–39.9%), as well decreasing bulk density (6.0%) alleviating salt stress (4.1–40.0%). Following incorporation, can also be improved, particularly microbial biomass (7.1–25.8%), facilitating enzyme activity (20.2–68.9%), ultimately plant growth. To properly assess soil, it important select related ecological service functions including production, quality, climate change, human will improve multifunctionality enhance current assessment methods. Finally, limitations future needs research biochar-based technologies soils are discussed. first conducted a global meta-analysis illustrating indicators. Moreover, offers valuable insights developing sustainable tools remediating soil.

Long-term effects of biochar application on the growth and physiological characteristics of maize

Frontiers in Plant Science, Journal Year: 2023, Volume and Issue: 14

Published: June 14, 2023

Biochar, as a soil conditioner, has been widely used to promote the growth of maize, but most current research is short-term experiments, which limits on long-term effects biochar, especially physiological mechanism biochar maize in aeolian sandy still unclear. Here, we set up two groups pot respectively after new application and one-time seven years ago (CK: 0 t ha-1, C1: 15.75 C2: 31.50 C3: 63.00 C4: 126.00 ha-1), planted with maize. Subsequently, samples were collected at different periods explore effect physiology its after-effect. Results showed that plant height, biomass, yield highest rates increase rate ha-1 22.22% biomass 8.46% compared control under treatment. Meanwhile, height increased gradually treatment (increased by 4.13%-14.91% 13.83%-58.39% control). Interestingly, changes SPAD value (leaf greenness), soluble sugar protein contents leaves corresponded trend growth. Conversely, malondialdehyde (MDA), proline (PRO), catalase (CAT), peroxidase (POD) superoxide dismutase (SOD) manifested an opposite In conclusion, can inducing biochemical characteristics, excessive ranging from 63.00-126.00 inhibited After field aging, inhibitory amount disappeared changed promoting effect.

Biochar can be used for multifunctional applications including the improvement of soil health and carbon storage, remediation contaminated water resources, mitigation greenhouse gas emissions odorous compounds, feed supplementation to improve animal health. A healthy preserves microbial biodiversity that is effective in supressing plant pathogens pests, recycling nutrients growth, promoting positive symbiotic associations with roots, improving structure supply nutrients, ultimately enhancing productivity growth. As a amendment, biochar assures biological through different processes. First, supports habitats microorganisms due its porous nature by formation stable micro-aggregates. also serves as nutrient source. alters physical chemical properties, creating optimum conditions diversity. immobilize pollutants reduce their bioavailability would otherwise inhibit However, depending on pyrolysis settings feedstock comprised contaminants polycyclic aromatic hydrocarbons potentially toxic elements activity, thereby impacting

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

Biochar, Journal Year: 2023, Volume and Issue: 5(1)

Published: July 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.
