Published: March 1, 2024

Salinization remains a major issue in soil degradation, for which biochar is potential solution. In this meta-analysis, using 660 paired observations from 99 peer-reviewed articles, we evaluated biochar's effect on salt-affected soils and identified the initial properties, properties experimental factors influencing its efficacy. The results showed that addition of had significant ameliorating soils. electrical conductivity saturated paste extract (ECe) was significantly reduced by 13.2%, such severe salinization (rather than slight moderate salinization). Meanwhile, cation exchange capacity increased 17.0%. However, no impact pH. Model selection analyses further indicated level salinity type feedstock were most important regulating response ECe to addition. summary, while our study highlights soils, particularly severely salinized it also underscores need more comprehensive research field. Additional necessary comprehensively address heterogeneity biochars, including their thorough characterization. addition, studies are required explore both salt-tolerant non-salt-tolerant plants

Unlocking the potential of co-applied biochar and plant growth-promoting rhizobacteria (PGPR) for sustainable agriculture under stress conditions

Chemical and Biological Technologies in Agriculture, Journal Year: 2022, Volume and Issue: 9(1)

Published: Aug. 22, 2022

Abstract Sustainable food security is a major challenge in today’s world, particularly developing countries. Among many factors, environmental stressors, i.e., drought, salinity and heavy metals are impediments achieving sustainable security. This calls for finding environment-friendly cheap solutions to address these stressors. Plant growth-promoting rhizobacteria (PGPR) have long been established as an means enhance agricultural productivity normal stressed soils being applied at field scale. Similarly, pyrolyzing agro-wastes into biochar with the aim amend proposed additive enhancement of soil quality crop productivity. Many pot some field-scale experiments confirmed potential increase Recently, studies combined PGPR improving productivity, under conditions, assumption that both additives complement each other. Most reported significant co-applied treatments than sole application or biochar. review presents synthesis addition providing insights mechanistic basis interaction Moreover, this highlights future perspectives research order realize co-application Graphical

Saline water is widely used as an alternative resource for agriculture to overcome the freshwater shortage in arid and semiarid regions. But long-term using of saline irrigation would negatively affect soil properties crop production, salinity should be properly managed reduce risks. In this study, with five levels electrical conductivities (ECiw) at 1.3 (CK), 3.4, 7.1, 10.6, 14.1 dS·m−1 were irrigate winter wheat summer maize annual double cropping system North China Plain (NCP) from 2006 2019, decide threshold value water. Crop yields continuously examined physicochemical monitored 2018 2019 after 12 years' irrigation. Results showed that 0100 cm layer could maintained a low level ECiw 3.4 dS·m−1. Soil salt accumulated seasons leached main root zone following seasons, which rainy region due monsoon climate. No significant difference was observed grain treatment compared CK treatment. The conductivity saturated extract (ECe), pH, sodium adsorption ratio, bulk density within top 030 increased increase ECiw, whereas organic carbon, porosity, macroaggregates (> 0.25 mm) content, activities catalase, urease alkaline phosphatase decreased, indicating deteriorated properties. between not apparent.

In the context of dwindling freshwater resources, it is imperative to comprehensively evaluate crop productivity and soil resource sustainability when considering use saline water for irrigation (SWI). This study aimed investigate effects SWI on salinity variation flat sowing cotton (Gossypium hirsutum L.) through a comprehensive 15-year field experiment conducted in North China Plain, encompassing six levels (ECiw 1.3, 3.4, 7.1, 10.6, 14.1, 17.7 dS m−1, respectively).

Exogenous carbon inputs alleviated salt-induced oxidative stress to cotton in salinized field by improving soil aggregate structure and microbial community

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 16

Published: March 27, 2025

High concentrations of salt ions in salinized soils not only destroy soil structure, but also inhibit crop growth. Straw and straw-derived biochar have great potential improving reducing salinity, environment, alleviating stress. However, the effects mechanisms exogenous addition different carbon sources on aggregate structure microbial community with salinization degrees cotton fields as well antioxidant defense system are still unclear. In this column experiment since 15 March, 2023, three contents (1.5 (S1), 5 (S2), 10 (S3) g/kg) five treatments (straw incorporation: 6 t/hm 2 (C1), 12 (C2); 2.25 (B1), 4.5 (B2); CK: no straw incorporation) were designed. Then, incorporation particle size distribution aggregates, bacterial fungal communities, leaf S1, S2, S3 explored. The results showed that incorporation, especially B2, significantly reduced content soils, increased proportion macroaggregates by 7.01%–13.12%, 5.03%–10.24%, 4.16%–8.31%, respectively, compared those CK. C2, abundances Actinobacteria, Acidobacteria, Enterobacteriaceae, decreased Proteobacteria, Besides, superoxide dismutase (SOD) catalase (CAT) activities salt-stressed leaves, malondialdehyde (MDA) peroxidase (POD) activity, It should be noted effect stress gradually growth increase salinity. summary, could reduce diversity, alleviate cotton.
