As climate shifts occur, these adaptable microbes adjust, affecting ecosystem dynamics. Climate-smart agriculture harnesses microbial partnerships for soil carbon sequestration and stress mitigation, safeguarding the food supply. Microbes support crop productivity and resilience while also managing pests and diseases in changing climates.

Microbial diversity acts as a buffer against climate-induced disruptions, underlining their role in sustaining ecosystem stability. Integrating microbial approaches into policies and practices becomes crucial for climate adaptation, paving the way for sustainable agriculture and water management. Novel microbial technologies hold promise in addressing climate-food-water challenges, while collaborative research remains essential for innovative solutions at this critical interface of science and policy.

The objective of this research was to comparatively evaluate the effect of microalgae biomass biofertilizer, derived from the production of <i>Arthrospira platensis</i> DHR 20 (Spirulina) in cattle wastewater under organic management (CW), on the development of arugula. It also examined the microbiological attributes of arugula leaves and the changes in soil chemical properties and structural composition of the soil post-experiment. The experiment consisted of three treatments: T1 – control, with urea application; T2 – CW; T3 – microalgae biofertilizer. The experimental design was completely randomized with seven replications and four plants per plot. The main conclusion of this research is that microalgae biomass biofertilizer presents nutritional potential for arugula, particularly as a source of N (187.5 mg L⁻¹) and K (92.9 mg L⁻¹), and can replace conventional urea fertilizer as a nitrogen source in the cultivation of arugula, with similar plant development quality according to the Dickson Quality Index. According to the SAR, the microalgae biomass biofertilizer and CW do not present soil sodicity restrictions and show a low to moderate level of restriction for soil use in terms of salinity. The average biofixation rate of 0.22 CO₂ L⁻¹ d⁻¹ obtained in the study suggests that <i>Spirulina</i> cultivation in CW is suitable for this greenhouse gas biofixation. Leaves from the three treatment groups yielded negative results for the presence of thermotolerant coliforms. Both microalgae biofertilizer and CW acted as soil conditioners, improving its structural quality when compared to soil fertilized with urea.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"235 11","pages":""},"PeriodicalIF":3.8,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142411172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study employed high-throughput sequencing and differential abundance testing to explore the mechanisms of STS changes and the formation of co‑occurrence network resistance to HMs in reclaimed soil succession. Our results revealed that (1) Re treatment significantly improved the physicochemical properties of the soil and reduced the levels of HMs. Compared with the control group (CK), the heavy metal content in Re treatment decreased as follows: Hg (50.76%) &gt; Cd (46.43%) &gt; Cu (43.91%) &gt; As (35.89%) &gt; Pb (33.49%) &gt; Cr (24.39%); (2) Compared with CK, the Shannon, ACE, and Observed species indices of bacteria in Re increased significantly by 11.70%, 549.33%, and 392.00% (<i>p</i> &lt; 0.05), respectively.

The validation process involves comparing simulated PM₁₀, PM_2.5, and meteorological parameters with in-situ measurements from stations at Pirana and S P Stadium during 16th-17th May and 16th-17th December 2018. The analysis focuses on six-hourly averaged data, highlighting the significant role of Wind Speed, Wind Direction, and Planetary Boundary Layer Height (PBLH) in the dispersion of air pollutants. The results show that the model using locally developed PM emissions significantly reduces bias and provides better spatial distribution patterns compared to EDGAR emissions. For instance, in May, the average simulated PM₁₀ using EDGAR emissions was 85 µg/m³, while the locally developed emissions yielded an average of 183 µg/m³, closer to the observed in-situ average of 178 µg/m³. Similarly, in December, the simulated PM₁₀ using EDGAR emissions was 97 µg/m³ compared to 232 µg/m³ from local emissions, with an in-situ average of 147 µg/m³. The spatial analysis reveals that during May, 52% of the western areas experienced 'Good' air quality in the morning, decreasing to 40% by the evening. In contrast, December showed more severe pollution, with 45% of the North–North Western city experiencing 'Moderately Polluted' air quality by evening. The correlation coefficients (R²) for PM₁₀ validation at Pirana and S P Stadium were 0.73 and 0.93 respectively in May using EDGAR emissions, improving to 0.77 and 0.91 with local emissions. This study underscores the need for improved emission inventories and mitigation strategies to enhance air quality in Ahmedabad.

The adsorption properties of trititanate and hexatitanate nanorods for the removal of heavy metal ions, Ni²⁺ and Pb²⁺ from simulated wastewaters at pH of 3‒7 and 20‒65 °C were investigated. The adsorption of Ni²⁺ and Pb²⁺ ions on sodium trititanate and hexatitanate nanorods are through ion exchange and electrostatic adsorption. The adsorption of Ni²⁺ and Pb²⁺ ions could be well fitted by the pseudo-second order adsorption kinetics and Langmuir adsorption isotherm.

Sodium trititanate nanorods exhibit higher adsorption capacities for heavy metal ions from wastewaters than sodium hexatitanate nanorods because the former has richer Na⁺ ions for ion exchange with heavy metal ions than the latter.
