We investigated the effects of different drought regimes (controlled, medium-drought (MD), and severe-drought (SD)] and nitrogen (N; with or without) addition on biomass and physio-biochemical responses in <i>Alhagi sparsifolia</i> seedlings. Both drought stresses significantly increased superoxide dismutase (O₂^•−), hydrogen peroxide (H₂O₂), malondialdehyde, and oxidized-glutathione in leaves and roots, thereby impairing growth and metabolism. Furthermore, there is a significant accumulation of fructose and glucose, but lower sucrose and starch, possibly due to higher sucrose synthase, α-amylase, β-amylase and hexokinase but lower sucrose phosphate synthase and fructokinase. Drought-stressed seedlings also displayed higher abscisic and, jasmonic acids, strigolactones, glucose-6-phosphate dehydrogenase (G-6-PDH), phosphoenolpyruvate carboxylase, O₂^•−-H₂O₂-scavenging enzymes, but lower gibberellin, cytokinin, and indole-acetic acid. However, N-addition quantifies the productivity of drought-stressed seedlings by improving the leaf relative water content (LRWC), biomass, chlorophyll-a, sucrose-synthesizing enzymes (SPP and SPS), and hormones. It also increased the G-6-PDH in stressed seedlings to satisfy the need for NADPH and reduced the sucrose and starch degrading enzymes, leading to higher starch and sucrose levels. Upregulation of O₂^•−-H₂O₂ -scavenging enzymes under N-supply reduced lipid peroxidation and improved the ascorbate–glutathione redox states.

Comparing the modified model with the original, it demonstrates superior performance in simulating SWC and NO₃⁻-N at different depths. The modified model exhibits increased root mean square error (RMSE) values (9.48%, 6.21%, 15.82%), Nash–Sutcliffe efficiency (NSE) values (9.39%, 27.74%, 46.14%), and index of agreement (d) values (1.34%, 1.22%, 1.91%) at three depths of soil layer with a 10 cm increment from 0 to 30 cm under all nitrogen treatments. Similarly, the modified model enhances soil nitrate content simulation, showing increased RMSE (13.72%, 7.48%, 9.99%), NSE values (9.93%, 19.33%, 13.75%), and d values (1.75%, 1.75%, 1.52%) at three soil depths. Furthermore, the modified model aligns well with measured values in simulating tomato yield, despite a slight insignificant increase in yield.

Consequently, the occurrence of abiotic stress is a major challenge to crop production, including the first phases of seed germination and plant establishment, that needs to be addressed. Farmers, especially in developing and underdeveloped countries, tend to use excessive amounts of fertilizer to increase the cultivated crop yields. Therefore, the adoption of sustainable agricultural practices is essential to satisfy the increased need for food safety and security in modern society while minimizing dependence on excessive use of agricultural inputs. There is growing interest in the use of Nano-fertilizers (NFs) to enhance seed germination and seedling establishment, crucial stages in the crop production process. Considering the limited number of studies in this field that have investigated the effects of NFs on enhancing seed germination under abiotic stress conditions, this review aims to address this research gap. The detrimental effects of various abiotic stress factors on seed germination parameters were discussed. In addition, NFs and traditional fertilizers were compared. Ultimately, different compositions, applications, current challenges, and future aspects of the application of NFs were explored. This study provided an insightful understanding of the benefits and challenges associated with the application of NFs in the early phase of plant development.

This study aimed to explore the driving factors regulating fertilization-induced OC conservation within soil aggregates. Methods: Soil aggregates of LM (large macro-aggregates, &gt; 2 mm), SM (small macro-aggregates, 0.25–2 mm), and MI (micro-aggregates, &lt; 0.25 mm) were obtained from an Ultisol treated with twenty-year no (CK), chemical (CF), and organic (OF) fertilizations.

Results: The CF only enhanced the OC content (g kg^− 1 soil) in LM by 27.4%, and the OF increased the OC contents in all aggregates by 14.2-60.8%. The fertilizations were conducive to the formation of large-size aggregates and the stimulation of soil aggregate stabilization. The order OF &gt; CF &gt; CK was observed in the concentrations (g kg^− 1 aggregate) of labile and recalcitrant OC within each aggregate. The fertilizations, particularly the OF, significantly improved the concentrations (g kg^− 1 aggregate) of chelated iron and aluminum oxides by 5.9-117.6%. The aggregate mass proportions, OC components, and iron/aluminum oxides displayed various roles in the OC preservation within every individual soil aggregate. Furthermore, the OC conservation was dominantly controlled by the recalcitrant OC within all soil aggregates.

Methods: Soil phenolic acid concentrations were determined using HPLC, analyzing seven phenolic acids, including p-hydroxybenzoic, ferulic, coumaric, and benzoic acids. The kinetic adsorption experiments evaluated phenolic acid adsorption rates and quantities across various soil types.

Conversely, the rhizosphere soil of monoculture <i>Acacia mangium</i> displayed the highest content, reaching 71 µg g^-1 in March.

In this study, a 10-year field experiment was used to determine the effects of different treatments (clean culture, biochar addition, straw cover, and acrylamide application used in conjunction with sod culture) on the cultivation of navel oranges. The activity of soil sucrase, acid phosphatase, and urease was assayed with salicylic acid colorimetry, paranitrophenol-sodium orthophosphate colorimetry, and sodium phenylate colorimetry respectively. Moreover, the fungi in soil samples were counted using a traditional plate counting method, fungi DNA was extracted and 18S rRNA genes were PCR-amplified, and subsequently analyzed by the Illumina HiSeq2500 platform. The nutrient uptake of orange and soil chemical properties were determined by inductively coupled plasma mass spectrometer (ICP-MS) and soil agrochemical analysis. Results showed that the soil chemical properties, soil microorganisms, enzyme activities, soil microbial diversity, and leaf nutrition of all sod culture treatments were significantly higher than those for clean culture. Moreover, adding biochar (6t/hm²) could promote the soil organic matter (SOM), the content of soil available nutrients such as phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), and boron (B), the activity of acid phosphatase and sucrose, and the number and diversity of fungi in the soil. Meanwhile, the leaf nutrient concentrations of treatments application of biochar (6t/hm²) and rice straw cover (9t/hm²) was significantly higher than that for the control treatment.
