Summary: The rhizosphere and drilosphere are hotspots of interactions between plants and soil organisms, and between earthworms and soil microbial communities, respectively. These interactions are influenced by plant species diversity and earthworm activity. Little is known about the effects of earthworms on microbial community activity under the influence of root-trait diversity in cases of multispecies plant covers.

Summary: This study investigated the interactive effects of microplastics, biochar, and earthworms on greenhouse gas emissions and soil microbial functional genes in vegetable-growing soil. The addition of biochar alone or combined with microplastics decreased soil CO2 emissions, while microplastics and biochar inhibited CO2 emissions and promoted N2O emissions in the presence of earthworms. The interactions of these substances also had significant effects on soil chemical properties and microbial abundances.

Summary: The study investigated the impact of warming and straw application on soil microbial biomass C, N and C/N in a winter wheat-soybean rotation cropland. It found that warming significantly increased microbial biomass C and C/N over the crop-growing seasons, while straw application did not have a significant effect. Soil microbial biomass C, N, and C/N were affected by different soil moisture conditions, with warming-associated water losses playing a key role in influencing them. The results suggest that soil microorganisms in agroecosystems may accumulate more C under future warmer climate conditions.

Summary: The development of zero-valent species of group 13-15 elements has been reinterpreted with the use of Lewis bases to stabilize such species. This has led to the isolation of E-n(0) derivatives with a variety of bonding and structural motifs due to the diversity of Lewis bases available. The exploration of allotrope chemistry relevant to materials science is proposed as a potential future direction for zero-valent main-group chemistry at the end of the article.

Summary: Elevated CO2 concentrations have a significant positive effect on soil microbial biomass, but this effect is influenced by factors such as atmospheric CO2 levels, experimental duration, and mean annual precipitation. Low CO2 levels in the short term and under high precipitation can promote the growth of soil microbial biomass, whereas long-term high CO2 levels result in a decrease in total microbial biomass.

Summary: The study examines the factors contributing to the deglacial Atlantic mid-depth delta C-13 change, finding that the increased remineralization due to the weakened AMOC plays a dominant role in the decrease of delta C-13. The surface end-members should be used in diagnosing mechanisms of delta C-13 changes, as their remineralization is more critical than that along the transport pathway to the deep ocean.

Summary: This study conducted a meta-analysis of 173 studies on the uptake and accumulation of metallic nanoparticles (MNPs) in crops. The results show that root application is the main method used, and plants preferentially take up essential elements as MNPs. Additionally, smaller particle size and more negative zeta potential increase metal accumulation, while non-essential elements are more commonly acquired as dissolved metals.

Summary: Organic farm management and the application of farmyard manure can promote the sequestration of soil organic carbon by improving the nutrient balance of macro- and micronutrients. However, there is a lack of quantitative information on micronutrients within the soil microbial biomass. This study investigated the effects of fertilisation differences and farm management on the soil microbial ionome and stoichiometry, and whether these changes are related to shifts in the microbial community. The results suggest that nutrient input and soil chemical properties play a major role in shaping the microbial stoichiometry and ionome, but the direct links between micronutrient stoichiometry and microbial community changes are uncertain due to potential confounding effects of pH changes.

Summary: The present study aimed to develop a method for assessing the elemental composition of soil microbial communities. Chloroform fumigation extraction was used to detect the concentrations of secondary and trace elements in soils. It was found that 0.01 M CaCl2 was the best-suited extractant, with a soil-to-extractant ratio of 1:20 and an extraction time of 1 hour. This method successfully extracted elements such as phosphorus, sulphur, potassium, sodium, magnesium, zinc, manganese, copper, nickel, vanadium, boron, silicon, and barium.

Summary: The functions of soils are closely related to their pore space and biogeochemical interfaces. The study of soil microaggregates can provide insights into their structure and functions. Advanced techniques allow us to assess the size, composition, and porosity of microaggregates and explore their role in element cycling. However, these techniques have specific requirements and limitations in sample preparation and analysis.

Summary: Prolonged paddy management alters the Fe isotope composition of soil and rice plants, indicating the origin of rice plants and the extent of past soil paddy management. The study found that prolonged paddy management reduces Fe concentrations in the topsoil, leading to an enrichment of heavy Fe isotopes. The Fe content in rice also increases with paddy age, while its Fe isotope composition resembles that of the Fe plaques on the roots rather than paddy soil.
