Secondary salinization of soil seriously hinders the healthy cultivation facility grapes. Biochar has been shown to mitigate negative effects saline stress on plants. However, long-term response mechanism between soil’s key physicochemical properties, ion concentration, and enzyme activity physiological resistance grape plants biochar combined with cow dung application alleviate secondary remains unclear. In this study, a field experiment was set up once in September 2021 five different treatments, including no amendments. which used as blank control (CK), (10 t·ha -1 , T1), (30 T2), mixed (5 +15 T3), +30 T4), respectively. The results showed that compared CK treatment, treatments significantly reduced total salt(TS) content electrical conductivity(EC) value; increased water-stable aggregates nutrient content; stimulated an increase urease (S-UE), sucrose (S-SC) phosphatase(S-ALP)activities; changed exchangeable calcium magnesium concentrations. Among T4 treatment TS EC by 73.03% 61.11%, chlorophyll malondialdehyde (MDA), activities superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) leaves. decreased MDA, SOD, POD, CAT 54.59%, 40.14%, 44.28%, 70.17% Correlation analysis balance ions stability aggregate structure were factors alleviating stress. conclusion, can oxidative improve quality grapes improving aggregates, coordinating concentration ions, stimulating activity.

The accumulation of salt in arable lands is a source significant abiotic stress, contributing to 10% decline the world’s total and threatening food productivity sustainability agriculture. About 76 million hectares productive land are estimated have been affected by human-induced salinization such as extreme deposits soil, which mainly caused actions humans. For instance, continued irrigation frequent use chemical fertilizers need be understood. To ensure availability, it essential improve upon traditional farming methods using current technologies facilitate reclamation saline-affected achieve high sustainable production. This review details innovative strategies modification metabolic pathways, manipulation antioxidant genetic engineering, RNA interference technology, engineered nanoparticles, arbuscular mycorrhizal fungi (AMF), organic amendments, trace elements for improving saline marginal lands. These were identified contributed improvement plants salinity tolerance diverse ways. plant metabolites amino acids, sugars, polyols, saponins, anthocyanins, polyphenols, tannins detoxify play crucial roles mitigating detrimental effects oxidative damage posed stress.

To mitigate the issues of severe farmland soil salinization, environmental degradation stemming from overuse chemical fertilizers, and suboptimal composition, a study was conducted to investigate influence different types ratios organic fertilizers on physical attributes saline–alkali soil. This aimed relationship between proportions moisture, fertilizer application rates, carbon molecular structure, environment in soils. Reducing substituting them with can improve quality lands. The results indicated that replacing part urea reduced salinity by 11.1 22.8% 0–60 cm layer, decreased pH 0.11 1.52%, increased redox potential (Eh) values 2.5 4.3% 0–20 layer mild moderate It also accumulation matter (OM) during growing season.

Agronomy, Год журнала: 2025, Номер 15(6), С. 1283 - 1283

Опубликована: Май 23, 2025

Coastal saline–alkali soils, characterized by poor structures and low fertility, limit sustainable agricultural development. This study aimed to investigate how green manure application influence soil aggregate stability organic carbon (SOC) sequestration in such coastal saline soils. Field experiments were conducted comparing the following five treatments: (1) control (CK); (2) ryegrass full incorporation (RF); (3) mulching (RM); (4) alfalfa (AF); (5) (AM). The results demonstrated that significantly increased large macroaggregate (>2 mm) proportions 20.60–56.70% while reducing microaggregates (<0.25 24.35–68.43%. SOC across 0–40 cm depth, primarily driven macroaggregates microaggregates, which contributed 23.7–73.5% 34.8–91.4% of total increase, respectively. Mulching treatments (AM/RM) surface sequestration, full-incorporation practices (AF/RF) boosted subsoil stocks. These highlight as an effective strategy rehabilitate soils enhancing providing technical guidance for rehabilitation regions.
