Soil moisture determines effects of climates and soil properties on nitrogen cycling: Examination of arid and humid soils.

While soil moisture has a significant effect on nitrogen (N) cycling, how it influences the dependence of this important biological process on environmental factors is unknown. Specifically, it is unclear how the relationships of net N mineralization (N) and soil moisture vary with soil properties and climates. In turn, how the relationships of N vs.

Halophytes increase rhizosphere microbial diversity, network complexity and function in inland saline ecosystem.

Salinization is an important global environmental problem influencing sustainable development of terrestrial ecosystems. Salt-tolerant halophytes are often used as a promising approach to remedy the saline soils. Yet, how rhizosphere microbes' association and functions vary with halophytes in saline ecosystems remains unclear, restricting our ability to assess the role of halophytes in remedying saline ecosystems.

Photocatalytic degradation of imidacloprid by optimized BiWO/NH-MIL-88B(Fe) composite under visible light.

Imidacloprid as a widely used neonicotinoid insecticide can cause harmful pesticide residue inevitably. Metal-organic frameworks (MOFs) were innovatively composited to improve the light absorption and degradation performance of BiWO semiconductor, which expanded the photodegradation application in solving environmental problems. Based on the synergistic effect of BiWO and NH-MIL-88B(Fe), a BiWO/NH-MIL-88B(Fe) (BNM) heterojunction photocatalyst with high-performance of photocatalytic degradation activities was successfully synthesized.

Drying-wetting cycles consistently increase net nitrogen mineralization in 25 agricultural soils across intensity and number of drying-wetting cycles.

An increase in extreme weather events such as heavy rainfall and extreme drought causes intensive and frequent drying-wetting (DW) cycles, which have strong effects on the availability of nitrogen (N) for plant growth and development. How the effects of DW cycles on N turnover vary with the intensity and number of DW cycles and soil properties has not been clearly addressed, which hinders predicting soil biogeochemical cycles in a changing world. Herein, we examined the response of net N mineralization in agricultural soils measured at a standard temperature (25 °C) to DW cycles varying in intensity and number.
