Summary: Our study found that the capability of microbial community to reduce its demand for external nutrients is responsible for the difference between the predictions and observations. The active part of microbial community instantly recycled N from decaying part of microbial community and very likely utilized internal P sources (i.e. polyphosphates). The results suggest that N recycling from dead microbial biomass and the internal microbial P sources warrant further investigation.

Summary: The study found that spring snowmelt triggers a sudden transition in the composition of soil microbial communities in alpine grasslands, which is closely linked to shifts in soil microbial functioning and biogeochemical pools and fluxes. Experimental manipulation of snow cover showed that earlier snowmelt advances the abrupt seasonal transition in a wide range of microbial and biogeochemical soil properties.

Summary: The study found that snowpack reduction had significant effects on the concentrations of dissolved organic carbon and nitrogen, nitrate concentration, and microbial biomass in different snow periods; although snowpack reduction did not significantly affect soil microbial biomass, it had a stronger impact on nitrate concentration and microbial respiration rate, especially in organic soil.

Summary: The study found that crops sown on November 17 had the highest levels of bacteria, fungi, actinomycetes, soil microbial biomass carbon, dehydrogenase activity, and available nitrogen, phosphorus, potassium, and sulphur. When using nutrient sources, the combination of 75% recommended dose of fertilizers, 25% nitrogen from pressmud, Azotobacto, and phosphorus solubilizing bacteria showed the highest microbial population and nutrient content.

Summary: This study conducted two experiments with sandy loam soil to investigate the influence of water content changes on soil respiration and nutrient availability. Results showed that microbial biomass nitrogen decreased after rewetting in previously moist soils, while it increased in previously dry soils. Additionally, available nitrogen levels changed significantly in response to different water content treatments.

Summary: In this study, the authors expanded the conceptual framework of carbon allocation for nutrient acquisition in plants by introducing a new parameter called carbon efficiency for nutrient acquisition (CENA). They found that CENA increases with higher nutrient availability, but reaches a plateau when the availability of one nutrient increases at the expense of another. The relationship between CENA and mycorrhizal plants may differ from non-mycorrhizal plants, with CENA potentially being higher in mycorrhizal plants under low nutrient availability. Additionally, the CENA of nitrogen-fixing plants is independent of soil nitrogen availability but increases with soil phosphorus availability. The researchers conclude that these updated frameworks provide a better understanding of how plants optimize belowground carbon allocation for nutrient acquisition under varying nutrient availability conditions.

Summary: This study aimed to assess the fertilizing effects of digestate on soil properties. The results showed that digestate not only contains essential nutrients for crops but also can alter the biogeochemical cycle of nutrients and soil functionality. However, at high doses, digestate application negatively affected soil enzyme activities, microbial biomass, and soil P and C cycling capacity.

Summary: Soil salinization is a serious global environmental problem that affects the sustainable development of agriculture. This study shows that salt-tolerant legumes Glycine soja and Sesbania cannabina can effectively ameliorate coastal saline soil by reducing salinity and increasing nutrient content. The enrichment of nitrogen-fixing bacteria, such as Azotobacter, in legumes contributes to soil nitrogen accumulation and improves the soil microbial community. Overall, this research highlights the importance of legumes and soil microbes in the phytoremediation of saline soils.

Summary: Coastal wetlands are important for terrestrial carbon balance as they act as natural blue carbon sinks. However, the effects of N enrichment on Rsoil in coastal wetlands are still unclear, hindering the estimation of carbon fluxes. This study found that long-term N enrichment increased Rsoil by boosting microbial biomass carbon, and also enhanced plant growth. The results suggest that N enrichment stimulates Rsoil in coastal wetlands through interactions between soil environmental conditions and plant growth.

Summary: Snow is crucial to the Arctic's energy budget, biogeochemistry, ecology, and people. While climate change shortens the snow cover period, snow mass has been increasing in many Arctic regions. Deeper snow thaws permafrost and releases ancient organic matter, contributing to greenhouse gas emissions. However, more snow also leads to warmer soil temperatures and increased carbon loss, impacting Arctic ecosystems and accelerating permafrost carbon release.

Summary: In the dwarf-shrub mountain tundra of the Khibiny Mountains postfire succession, the study found that the soil's water-soluble organic matter is not significantly affected by medium-intensity fires, with the activity of WSOM mineralization mainly determined by its properties. The biodegradation process involves fast and slow mineralized pools, with the fast pool initially dominating after a fire but gradually decreasing, demonstrating a biokinetic selection of aromatic hydrophobic compounds resistant to microorganisms.

Summary: The study showed that a significant part of bacterial communities in Antarctic soils can pass through filters with pore sizes of 0.2 μm. During incubation at increased humidity and positive temperatures, the total number of cells and the FFB fraction showed an inverse relationship, while there were no significant changes in taxonomic diversity. Additionally, the transition of active bacterial cells to small dormant forms is seen as a survival strategy in extreme conditions, contributing to the stable functioning of microbial communities in Antarctic soils.

Summary: This review briefly summarizes the mechanisms of adaptability development in Acinetobacters to different living conditions. It has been shown that plasmids play a key role in the formation of adaptability. The structure and gene composition of plasmids depends on the lifestyle of host bacteria, with modern strains enriched in antibiotic-resistant genes. The study concludes that Acinetobacter plasmids can ensure bacterial survival under various stresses and provides an overview of horizontal gene transfer mechanisms.

Summary: This study investigated the soil factors influencing the development of biological denitrification inhibition (BDI) and found that initial soil moisture, ammonium concentration, and the initial abundance of certain microbial genes play significant roles in BDI development. Additionally, the research highlighted the relevance of biotic factors in explaining BDI and proposed the use of procyanidin concentration from plant belowground system as a new proxy for measuring BDI intensity.

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.
