Summary: Excessive nitrogen fertilization in agricultural ecosystems affects microbial nitrogen-cycling processes in soil, with long-term nitrogen input increasing the abundance of microorganisms involved in most nitrogen-transforming processes but decreasing that of nitrogen-fixing assemblages. The composition of microbial groups involved in each nitrogen-transforming process is altered by fertilization, despite the abundance of functional genes remaining unchanged. Different microbial taxa respond differently to nitrogen fertilization within the same functional group, which may be important for sustaining microbial nitrogen cycling in complex and dynamic environments.

Summary: Soil microbial communities are crucial for agroecosystem productivity, but the relationship between microbial community complexity and crop production remains poorly understood. In this 26-year fertilization experiment, it was found that the use of mineral combined with organic fertilizer significantly increased maize yield compared to no-fertilizer and mineral fertilizer treatments. The different fertilization methods also had profound effects on soil chemical properties and microbial community composition. The study highlights the importance of microbial community complexity in sustaining crop production.

Summary: Soil microorganisms play essential roles in nutrient cycling and soil quality in agriculture. Long-term fertilization can impact soil microbial diversity and community structure, with chemical fertilizer combined with pig manure showing greater effects than chemical fertilizer alone. Soil properties such as pH and nutrient levels are key factors influencing bacterial and fungal taxa after years of fertilization in sandy soil.

Summary: Climate changes and anthropogenic nutrient enrichment have negative impacts on plant diversity and ecosystem functions. Soil microbes, particularly arbuscular mycorrhizal fungi (AMF), play a crucial role in mediating plant community response to nutrient enrichment. Shifts in mycorrhizal responsive plants' competitive abilities can drive plant community change to anthropogenic eutrophication, highlighting the importance of mycorrhizal mutualism in ecological restoration following soil community degradation.

Summary: Fertilization affects soil microbial community by changing soil organic carbon and nutrient availability. Inorganic and organic fertilization lead to stoichiometric imbalances in soil and microbial biomass, driving shifts in microbial community structure. Soil pH and C, N, P stoichiometric imbalances are key factors influencing the composition of soil microbial communities after long-term fertilization.

Summary: Extensive grassland degradation poses a threat to ecological security due to climate change and intensified human activities. Predicting grassland degradation on a large scale is challenging due to its complexity. The emergence of machine learning algorithms provides a potential solution. In this study, random forest and neural network models were used to predict grassland degradation. The random forest model achieved high prediction precision, while the neural network model did not. Geographic, meteorological, and plant variables explained 61.8% of the total variance, which was increased to 72.8% by microbial markers.

Summary: This study examines the sensitivity of key ecosystem processes (community biomass and ecosystem CO2 fluxes) to droughts with different seasonal timing on a temperate semiarid grassland. The results show that belowground and total biomass have positive sensitivity to early and middle droughts but negative sensitivity to late droughts, while aboveground biomass is insensitive to all droughts. Ecosystem CO2 fluxes have the highest negative sensitivity to early droughts and the lowest negative sensitivity to middle droughts. The study highlights the crucial role of seasonal drought timing in regulating the sensitivity of key carbon cycle processes to droughts.

Summary: This study examined the response of soil microbes to grazer exclosure duration in alpine grassland soils on the eastern part of the Qinghai-Tibetan Plateau. The findings suggest that longer exclosure durations can increase the relative abundance of nitrogen fixers and decrease the proportions of plant pathogenic fungi, contributing to enhanced soil nitrogen fixation and grassland health. However, there may be a resource cost as plant productivity and soil organic carbon decrease with the extension of grazer exclosure duration.

Summary: The study found that phosphorus addition has a positive effect on soil microbes globally, increasing their abundance regardless of nitrogen input. This effect is more pronounced in areas with higher phosphorus addition rate, mean annual temperature, and mean annual precipitation. Higher phosphorus addition frequency leads to a higher abundance of bacteria compared to fungi, but a lower fungi-to-bacteria ratio. The effect of phosphorus addition on bacteria and fungi ratios is more significant in forests and varies with different forms of phosphorus fertilizers.

The results showed that the biochar preferably absorbed highly chlorinated CBs (PeCB and HCB) over low-chlorinated CBs (MCB and 1,2-DCB). The molecular orbitals, electron cloud distribution, and configuration of the CBs were calculated to investigate the adsorption mechanisms.

Summary: In sugarcane cropping systems, high rates of N fertiliser create conditions that promote soil denitrification and result in high emissions of N2O. We investigated the effect of cane trash removal and the use of DMPP on N-2 and N2O emissions and found that both strategies can effectively reduce N losses and N2O emissions while keeping the benefits of cane trash retention.

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.
