Water scarcity and soil degradation pose challenges to sustainable agriculture. Phosphogypsum, a low-cost solid waste, shows potential as amendment, but its impact on water saving quality need further study. This research assessed the effects of phosphogypsum application rates (CK: no phosphogypsum, 0.075%, 0.15%, 0.3% 0.6%) infiltration, retention, salinity, quality, crop yield irrigation productivity (IWP) identify optimal rate. Phosphogypsum altered pore structure gradients, slowing wetting front migration, increasing infiltration duration (102 158 min), cumulative (17.37 27.44 cm) (p < 0.05) content (18.25% 24.33%) rate increased from CK 0.6%. It also enhanced retention by enhancing aggregation reducing evaporation.By promoting formation stabilization aggregates, (CK reduced bulk density 1.20 g/cm3 1.12 0.05), while porosity, available nitrogen urease activity 3.70%, 39.42% 82.61%, respectively 0.05). These enhancements provided strong foundation for improved performance. Specifically, through three pathways: (1) improving physical properties, which influenced nutrients then enzyme activities; (2) directly affecting nutrients, impacted activities yield; (3) boosting activities, leading yield. The comprehensive benefits initially decreased, with an 0.45% determined TOPSIS, method that ranks alternatives based their proximity ideal solution, considering factors including IWP. findings confirm feasibility effective resource enhance efficiency agricultural practices.

Bayer red mud (RM)-based geopolymers are economical and ecofriendly alternatives to cement because of their superior performance. This study investigated alkali-activated cementitious materials by combining RM, fly ash (FA) slag, the mixtures were used produce composites. The influence Si/Al molar ratio (3.30–3.79) on initial properties (setting time flowability) hardened (compressive strength, drying shrinkage water permeability) composite was studied. Na2O content fixed at 4 wt%, thermal activation temperature 800 °C. phase evolution geopolymerization mechanism effect material FTIR, XRD, TG–DTG SEM–EDS. results M1.2Si333 indicated that compressive strength blends can reach 33.5 MPa 28 days, with a rate 1.20%. Compressive decreases, while increases higher ratio. Microstructural analyses revealed low alkali activator modulus enhance dissolution precursors form C–(A)–S–H gels, which increase strength. promoted application RM-based geopolymer-engineered enhanced resource efficiency bauxite residue.

The resource utilization of red mud (RM) has attracted widespread attention for achieving the waste-to-waste treatment goal. In this work, RM catalysts were synthesized at different calcination temperatures by a simple method. temperature had great effect on catalyst activity in catalytic combustion biodiesel wastewater. calcined 350 °C (RM350) exhibited best activity. chemical oxygen demand (COD) and COD removal rate treated wastewater reached almost 0 mg/L 100%, respectively. was significantly higher than 90.703% prepared α-Fe2O3 same temperature. Characterization results showed that high specific surface area 60.03–64.15 m2/g well-developed mesoporous structure, as did not exceed 400 °C, which beneficial adsorption diffusion. Meanwhile, most Fe2O3 existed an amorphous form abundantly presented surface, lowering reduction enhancing its reducibility. Furthermore, dispersion, leading to increase efficiency.

Red mud and phosphogypsum are two typical industrial by-products. The preparation of red mud/phosphogypsum-based artificial soils offers a promising novel solution to the efficient synergistic disposal them. Fungi, as key drivers, can promote continuous development ecological improvement soils. This study is first report characteristics fungal communities in three after one year incubation. preliminary formation (with relatively low diversity) resulted total 3 phyla, 81 genera, 144 operational taxonomic units (OTUs) Ascomycota was dominant phylum each soil (>99.5%), high-abundance genera included Unclassified_c_Sordariomycetes, Unclassified_o_Sordariales, Emericellopsis, Kernia, Unclassified_f_Nectriaceae, Ramophialophora, Schizothecium, Iodophanus. There were significant differences among compositions which affected material cycling, succession, maturation varying extents. According FUNGuild prediction communities, saprotrophic fungi (such undefined saprotroph, dung saprotroph–undefined saprotroph) played roles promoting degradation humification organic matter cycling carbon Fungal had strong correlations with many environmental factors pH, matter, available nitrogen, phosphorous, sucrase, urease, acid phosphatase, alkaline catalase), indicating interactions between not only conducive optimization structure but also promotes balanced homogeneous distribution various substances, gradual its functions. provides an important scientific basis for clarifying mechanisms mycogenesis during

Background Currently, vaccination has consistently posed challenges in preventing the Porcine reproductive and respiratory syndrome virus (PRRSV), so there is an urgent need for effective controlling strategies. Ma-Xing-Shi-Gan-San (MXSGS), a traditional Chinese medicine (TCM) formula used pulmonary diseases disorders, proven treating H1N1 COVID-19. Herein, we evaluated whether MXSGS exhibits potent antiviral activity against PRRSV. Methods First, PRRSV-infected Marc-145 cell model was established. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) tissue culture infective dose (TCID₅₀) assay were performed to assess inhibitory effects of on PRRSV during different administration stages. Network pharmacology then employed identify key active ingredients core potential targets In addition, gene ontology (GO) Kyoto Encyclopedia Genes Genomes (KEGG) analyses conducted elucidate signaling pathways modulated by MXSGS. Lastly, candidate validated molecular docking analysis. Results significantly inhibited through prophylactic therapeutic suppressed multiple phases viral life cycle, including attachment, internalization, replication, release. network results, 82 118 related identified. Among them, Calycosin, Odoratin, Glyzaglabrin, 7,2′,4′-trihydroxy-5-methoxy-3-arylcoumarin, Eriodictyol selected as ingredients. ALB, PPARG, CASP3, STAT3, TGFB1, JAK2, TLR4, PRKACA, PRKACB screened targets. Furthermore, pathway functional enrichment analysis revealed that impact mainly involved Toll-like receptor pathway, typical NF-κB signaling, positive regulation interleukin-6 production, Th17 differentiation, inflammatory response, defense response. indicated excellent binding affinity between ingredients, with all energies &lt; −6.0 kcal/mol. Conclusion vitro experiments exhibited considerable anti-PRRSV activity. Using approaches, five six identified, underscoring promising pharmaceutical agent
