The combined effects of tillage and organic amendments on microbial respiration its contribution to soil hydraulic conductivity are still uncertain in the 0–40 cm layer a loess soil. We conducted two-year field experiment explore amendments, their interaction respiration, aggregate stability, pore parameters, Loess Plateau. Three methods (conventional (CT), deep (DT) no (NT)) plus five fertilizer treatments (mineral (control) alone along with 20 t ha−1 wheat straw (MWS), husk (MWH), farmyard (MFS) bioorganic (MBF)) were set up as experimental treatments. findings demonstrated that significantly increased saturated compared control 0–10 10–20 layers. Soil had indirect by improving water stability macroporosity. Additionally, hydrological parameters significant 20–40 layer. NT-MBF resulted greatest conductivity, which was directly correlated soil’s strong organization. Given issue subsurface compaction our study area, it is recommended local farmers adopt enhance microbial, structural properties.

Wildfires are significant disturbances that reshape soil ecosystems, impacting properties, microbial communities, and enzyme activities. In Pinus tabulaeformis forests in northern China, the effects of wildfire on health, particularly Actinobacteriota enzymatic functions, remain poorly understood. This study investigates both direct indirect fire severity these factors examines how fire-induced changes properties mediate responses. Our findings show significantly alters chemical including an increase pH a reduction organic carbon water content, under high severities. These directly impact with showing resilience light moderate intensities but declining severity, especially subsoil layers. Soil enzymes, such as urease protease, played crucial role mitigating negative impacts nutrient cycling. Their activity promoted availability, aiding ecosystem recovery, even intensity reduced overall fertility. Structural Equation Modeling (SEM) further revealed relationships between Actinobacteriota, shaped by thermal complex interactions mediated moisture levels. underscores importance considering mutual activities post-fire recovery. The highlight while high-severity fires disrupt health dynamics, enzymes can help regulate enhancing cycling supporting stability. insights contribute to better understanding wildfire-induced degradation provide actionable strategies for restoration management fire-prone ecosystems.

Response of the Stabilization of Organic Carbon to Straw Incorporation and Nitrogen Application: Evidence from Carbon Fractions and Bacterial Survival Strategies

Agronomy, Год журнала: 2025, Номер 15(5), С. 1034 - 1034

Despite the global imperative to enhance carbon sequestration in agricultural landscapes, saline–alkali soils present distinctive soil–microbe constraints that limit our understanding of optimal management strategies. This study addresses critical knowledge gaps regarding mechanistic relationships between bacterial community structure and stabilization processes soil. A three-year field experiment was conducted Yellow River Delta, China, with two N levels (N1, 270 kg ha−1; N2, 210 ha−1) three C treatments (S0, 0 S1, 5000 S2, 10,000 ha−1). SOC by straw incorporation increased 16.34–22.86% 8.18–11.91%, no significant difference S1 S2 treatments, because specific mineralization rate (SCMR) treatment 13.80–41.61% higher than treatment. The reduced nitrogen application (N2) enhanced efficiency 3.40–12.97% compared conventional rates, particularly when combined half incorporation. Furthermore, N1S1 treatment, N2S1 induced qualitative transformations chemistry, increasing aromatic compounds (28.79%) while reducing carboxylic fractions (10.06%), resulting structural stability sequestered carbon. Bacterial analysis revealed shifts composition under different treatments. Half (S1) abundance oligotrophic strategists (Verrucomicrobiae Acidimicrobiia) decreasing copiotrophic bacteria (Bacteroidia), indicating a transition from r-strategy k-strategy microbial communities fundamentally altered cycling. were beneficial stabilize composition, reduce optimize survival strategy, thus achieve sequestration.

Soil management has a direct impact on its physical properties and crop productivity. In the case of pitahaya (Hylocereus spp.), mulch could be essential for conserving soil moisture structure. This study analyzed how in cultivation affects at different particle sizes (sand, silt, clay). Two plots were evaluated: one with other traditional management, assessing moisture, bulk density, size depths. Statistical analysis was performed using ANOVA Tukey test 5%. The results revealed that soils managed showed higher surface layer (0–5 cm) lower density compared to unmulched soils. suggests reduces evaporation helps improve Mulch is suggested as strategy optimize quality crops, thus promoting productivity sustainability.
