The effect of AMF combined with biochar on plant growth and soil quality under saline-alkali stress: Insights from microbial community analysis

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 281, P. 116592 - 116592

Published: June 19, 2024

Arbuscular mycorrhizal fungi (AMF) and biochar application individually can enhance plant tolerance to saline-alkali stress promote growth efficiency. However, little is known about the potential synergistic effects of their combination on improving soil quality under stress. This experiment adopted potted method explore four treatments switchgrass quality: (BC), Rhizophagus irregularis (Ri), + Ri (BR) a control without or (CK). Compared CK treatment, biomass increased by 92.4 %, 148.6 177.3 % in BC, Ri, BR treatment groups, respectively. Similarly, rhizosphere index 29.33 22.7 49.1 respective groups. The significantly altered microbial composition diversity. Notably, compared other treatments, archaeal α-diversity group showed significant decrease. relative abundance bacteria, archaea at genus level (e.g., Bacillus, Trichome candidatus_methanopenens). Network analysis that complexity closeness interactions between different taxa were stronger than with being more prominent. In summary, combined has better effect promoting stress, soil, increasing study provides new approach for efficient development utilization land.

Soil organic carbon accumulation mechanisms in soil amended with straw and biochar: entombing effect or biochemical protection?

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

Published: Feb. 12, 2025

Abstract Converting crop residues into biochar and subsequently incorporating it soils is a promising strategy to improve carbon sequestration in agroecosystems. However, differences the potential mechanisms for soil organic (SOC) accumulation between its feedstock materials remain unclear. This study performed nine-year field experiment involving four treatments Mollisol: mineral fertilizers alone combined with maize straw or biochar, control without amendments. The main objectives of this were assess how incorporation influence SOC content, chemical composition, microbial necromass (MNC) community characteristics. Compared alone, significantly ( P < 0.05) increased while (40.5% increase) had more pronounced effects than (23.7% increase). Similarly, both MNC content boosted biomass, but impact did biochar. Additionally, markedly aromaticity by 26.6% 0.05), reduced 2.85% > 0.05). Fungi, rather bacteria, played crucial role increasing through their inputs under incorporation. Our results demonstrated that enhanced primarily entombing effect necromass, biochemical protection from recalcitrant aromatic carbon. present findings provide valuable insight practices lead maximize sequestration.

Remediation of Pb-contaminated soil using biochar-based slow-release P fertilizer and biomonitoring employing bioindicators

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: Jan. 30, 2023

Abstract Soil contamination by Pb can result from different anthropogenic sources such as lead-based paints, gasoline, pesticides, coal burning, mining, among others. This work aimed to evaluate the potential of P-loaded biochar (Biochar-based slow-release P fertilizer) remediate a Pb-contaminated soil. In addition, we aim propose biomonitoring alternative after soil remediation. First, rice husk-derived was obtained at temperatures (450, 500, 550, and 600 °C) (raw biochars). Then, part resulting material activated. Later, raw biochars activated were immersed in saturated KH 2 PO 4 solution produce biochars. The ability materials immobilize increase bioavailability evaluated an incubation test. incorporated into doses 0.5, 1.0, 2.0%. After 45 days, samples taken biomonitor remediation process using two bioindicators: phytotoxicity test enzyme activity. Activated produced 500 °C has been found present best conditions for significantly reduced increased P. enzymatic activity correlated with decrease bioavailable but not Biomonitoring is promising evaluation soils processes.

An Overview of Climate Change Impacts on Agriculture and their mitigation strategies

Published: July 19, 2023

In recent days, the adverse effect of climate change on soil properties in agriculture sector is a dreadful reality worldwide. Climate change-induced abiotic stresses such as salinity, drought and temperature fluctuations are devastating crops’ physiological responses, productivity overall yield which ultimately posing serious threat to global food security agroecosystems. The applications chemical fertilizers pesticides contribute towards further deterioration rapid climate. Therefore, more careful, eco-friendly sustainable strategies required mitigate impact climate-induced damage sector. This paper reviews recently reported damaging impacts various crops along with two emerging mitigation strategies; biochar biostimulants, light studies for combating worsening deteriorated environment yields, properties, environment.
