Nitrogen (N), an essential element for organisms, is required for the synthesis of key cellular molecules, such as proteins and nucleic acids.Biological nitrogen fixation (BNF) driven by diazotrophs is a fundamental process underpinning the primary productivity of terrestrial ecosystems and plays a pivotal role in the global nitrogen cycle. However, the relationships between BNF function and soil diazotroph taxa with different nich...
Nanomaterials (NMs) have at least one dimension in the nanoscale range of 1–100 nm. Compared with traditional materials, NMs have larger specific surface areas, higher reactivity, unique structures, and extraordinary photoelectric properties. Soil is the primary sink for released nanomaterials (NMs), but the understanding of the impacts of NMs on the soil microbiome remains fragmented. Moreover, there is currently lack of systematic approaches to evaluate the microbial ecological risks of NMs. In this study, Prof. Ying TENG and hi...
Soil organic carbon (SOC) is the largest carbon pool in terrestrial ecosystems and is closely associated with the global carbon cycle through decomposition and accumulation processes. SOC is crucial to changing soil physicochemical and biological properties, thus governing the soil ecosystem ...Iron oxides supposedly provide physicochemical protection for soil organic carbon (SOC) under anoxic conditions. Likewise, biochar can modulate the composition of soil microbial communities. However, how Fe oxides and microbial communities influence the fate of SOC with biochar amendment rema...
The rapid development of the world economy has led to the release of large amounts of anthropogenic cadmium (Cd) into the atmosphere. The released Cd is ultimately deposited on the earth surface, which is absorbed by crops and accumulates in food chains. Rice roots and leaves were exposed to cadmium (Cd)-contaminated particles in a greenhouse to modify the fractionation during Cd uptake and transport in the plants by using the Bayesian mixing model. The exposure to atmospheric Cd in rice near a copper smelter was determined under the field co...
Nitrogen is a limiting nutrient for degraders function in hydrocarbon-contaminated environments. Biological nitrogen fixation by diazotrophs is a natural solution for supplying bioavailable nitrogen.Nitrogen is a limiting nutrient for degraders function in hydrocarbon-contaminated environments. Biological nitrogen fixation by diazotrophs is a natural solution for supplying bioavailable nitrogen. Here, Prof. LUO Yongming and his team from the Institute of Soil Science, CAS, determined whe...

Without standard methods to trace MPs/NPs in differ... As emerging contaminants, microplastics and nanoplastics (MPs/NPs) are increasingly widespread in soil environment. The present paper reviews available analytical methods for detecting MPs/NPs in soil and plants, and examines the migration processes of MPs/NPs at multiple interfaces as well ...
