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. This study will provide a scientific basis for improvement utilization soils.

Soil Organic Carbon and Humus Characteristics: Response and Evolution to Long-Term Direct/Carbonized Straw Return to Field

Agronomy, Journal Year: 2024, Volume and Issue: 14(10), P. 2400 - 2400

Published: Oct. 17, 2024

While numerous studies have examined the effects of direct and carbonized straw return on soil fertility, most focus short-term impacts. Long-term research is needed to understand how these practices affect fertility organic carbon transformation, providing guidance for use biochar in agriculture. This study long-term corn (CS), (BIO), biochar-based fertilizer (BF) applied over 5, 10, 15 years aggregates, carbon, humus composition a peanut field microplot experiment. Using pig manure compost (PMC) as control, we assessed water-stable aggregate distribution, content carbon’s infrared spectral characteristics. The goal was different utilization methods impact retention sustainable agricultural practices. results showed that (BIO) had significantly better effect increasing proportion stability large aggregates compared (CS) (BF). After ten continuous fertilization, soils treated with BIO higher than CS. fifteen BF similar CS treatment. Additionally, primarily accumulated 2–0.25 mm (SMA), treatment improved quality humus. FTIR spectra indicated application increased aromatic soil, enhancing carbon. returns stability, quality, contributing sequestration. Fertilization duration directly indirectly regulated formation through its while materials influenced indirectly.

Comparative effects of different types and doses of biochar on soil quality indicators and arugula growth under saline conditions

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: March 24, 2025

Abstract Population and food demand increased rapidly so to face this increment; we must dramatically increase crop production ensure global security. Hence, saline agriculture is a possible solution for producing in salt-affected soils using water irrigation. The objectives of study were investigate the effects applying different types doses biochar soil under irrigation by on quality indicators growth parameters yield arugula plant. Four biochar: banana leaves (BLB), rice straw (RSB), sorghum stalks (SSB), wood chips (WCB) applied pots at levels 1%, 3%, 5% (w/w). This pot experiment was cultivated with (6.2 dS m − 1 ). Total available nitrogen significantly relative control treatment (unamended soil) 41%, 34%, 43%, 33%, 24%, 44% adding 3%WCB, 5%WCB, 1%BLB, 3%BLB, 5%BLB, 5%SSB, 1%RSB, 5%RSB treatments, respectively. Results showed significant increases potassium (K) over 48%, 125%, 410%, 738%, 137%, 352%, 632%, 158%, 576%, 849% 1%SSB, 3%SSB, 3%RSB, Cation exchange capacity 26%, 22%, 30%, 58%, 31%, 54%, 28%, 48% 5%RSB, Relative treatment, fresh biomass plant improved 97%, 143%, 76%, 129%, 103%, 146%, 81%, 57%, 121%, 97% highest value biomass, uptake, phosphorus uptake observed 3%SSB applications. According results obtained from our study, recommend 3% which promising approach rehabilitate use sustainable production, attributed effective improvement nutrient productivity, conditions as it enhances tolerance plants salt stress well supply quality. Also, saves costs addition compared dose. also provided useful information about optimal quantities used improve productivity soils.
