Summary: Complexes formed by organic matter and clay minerals play a crucial role in the migration and transformation of pollutants in soil systems. This study focused on the preparation and analysis of humic-acid-montmorillonite (HA-MT) and humic-acid-kaolin (HA-KL) complexes, and investigated their adsorption-desorption characteristics for aniline. The results showed that the complexes exhibited enhanced flaky and porous structure, increased aromaticity, and higher adsorption capacity compared to pristine clay minerals. The adsorption of aniline onto the complexes was nonlinear and increased with higher HA content, with HA-MT showing higher adsorption capacity than HA-KL. After adsorption, the specific surface area of the complexes decreased, the surfaces became more complex, and the aromaticity decreased.

Summary: Low-molecular-weight organic acids (LMWOAs) in soil can affect the transport and behavior of microplastics (MPs) by interacting with mineral interfaces. This study investigated the effect of oxalic acid on mineral interfaces and its role in stabilizing MPs. The results showed that oxalic acid increased the stability of MPs on minerals and created new adsorption pathways, depending on the mineral bifunctionality induced by oxalic acid. In the presence of oxalic acid, the stability of hydrophilic and hydrophobic MPs on different minerals was significantly improved. Overall, these findings provide important insights into the environmental behavior of emerging pollutants and the role of organic acids in mediating their interactions with minerals.

Summary: In this study, the roles of dissolved organic matter (DOM) and organo-mineral associations (OMAs) in electron transfer were investigated during microbial Fe-(III)-mineral reduction. Only when both DOM and OMAs were present, significant electron transfer occurred. The proportion of DOM and OMAs showed a positive correlation with the extent of Fe-(III) mineral reduction, but the variation in DOM proportion had a stronger effect on the reduction compared to OMAs. These findings provide new insights into how organic carbon facilitates iron transformation and the associated biogeochemical cycling of nutrients and contaminants in forest soil systems.

Summary: Understanding the impact of soil fauna on soil aggregate dynamics is crucial for soil science, especially in tropical countries where soil erosion is a major issue. In this study, we examined the properties of soil sheeting built by two functional groups of termites and found that the stability of non-fungus growing termites' sheeting was related to the surrounding soil properties. However, the stability of fungus growing termites' sheeting did not have direct or indirect correlations with measured variables. These findings suggest that FG and non-FG termites have different functional consequences on soil aggregate stability in tropical soils.

Summary: This study assessed the fate of C and N compounds during the composting process of cattle and pig slurry anaerobic digestates. It found that there was no isotopic discrimination during composting, indicating the previous stabilization of the manure. Additionally, the composts increased N values and delta N-15 soil values, and the plants grown on compost-amended soils showed higher N and delta N-15 abundance compared to control and inorganic fertilized plants. Overall, the delta N-15 abundance of anaerobic digestate composts could be a useful tool for detecting the type of fertilizer used in agricultural production.

Summary: This study examined the biosynthesis and characterization of selenium nanoparticles (SeNPs) using two endophytic selenobacteria. The results showed that both strains were suitable for producing SeNPs with different properties. The SeNPs were surrounded by the proteins, lipids, and polysaccharides of bacterial cells, and the functional groups present in SeNPs from one strain were higher in number than in the other strain. The findings support the potential of these endophytic strains as biocatalysts for producing high-quality Se-based nanoparticles, and future efforts should focus on evaluating their bioactivity and determining how the different features of each SeNP modulate their biological action and stability.

Summary: It is estimated that if all legal active mining sites in Brazil are exploited over the next decades, it could result in the emission of 2.55 Gt CO2eq, largely due to the loss of vegetation and soil. To offset these emissions, the construction of soils from mine and other wastes (Technosols) is proposed, which could potentially offset up to 60% (1.00 Gt CO2eq) of soil-related CO2 emissions and restore important soil-related ecosystem services.

Summary: Soil microbial community coalescence, the mixing and interaction of microbial communities, has been found to enhance the stability and complexity of rhizobacterial networks, leading to improved plant health and biomass. This study investigated the effects of different degrees of bacterial community coalescence on plant disease resistance by mixing soils from healthy and diseased habitats for watermelon planting. The results showed that mixing in more healthy soil reduced the plant disease index and increased biomass by improving the stability and complexity of the rhizobacterial network. Core taxa Nitrospirillum and Singulisphaera were enriched in the rhizosphere from healthy soils and played important roles in disease suppression and regulating the positive cohesion and modularity of the networks. Overall, these findings provide insights into the potential mechanism of microbial community coalescence for improving plant microbial community function and suggest new tools for enhancing plant fitness via soil microbiota mixing.

Summary: Collembolans, the diverse group of soil invertebrates, are affected by anthropogenic climate warming, which alters their diversity and density. In addition to abiotic stressors, changes in food availability, specifically the abundance of saprotrophic and mycorrhizal fungi, influence Collembola responses to climate warming. Collembolans prefer saprotrophic fungi but rely on mycorrhizal fungi when food sources are scarce. Understanding the mechanisms behind these dietary shifts in warm-dry and warm-wet soil conditions is crucial for predicting the impact of climate change on Collembola-fungal interactions.
