E-mail：hyyao@iue.ac.cn
Article : https://doi.org/10.1016/j.geoderma.2020.114923Biological nitrogen (N) fixation is one of the most significant parts of the N cycle in terrestrial ecosystems, and this process is carried out by soil diazotrophs. However, knowledge of diazotroph assembly processes and activity in response to diverse fertilization strategies in agroecosystems across a large geographical scale is still lacking.MENG Xiangtian and Prof. YAO H...

E-mail：mptian@iue.ac.cn
Article : https://doi.org/10.1016/j.jhazmat.2020.124904Arsenic is a metalloid element found ubiquitously in the environment in either an organic or inorganic state. General populations are widely exposed to arsenic via digestion and inhalation. Environmental arsenic exposure is associated with multiple adverse health outcomes, including male reproductive toxicity. Arsenic is endocrine disruptors and classified as the reproductiv...

Scientists reveal the effect of inhibitors on the fate of fertilizer nitrogen and soil denitrification
Increasing evidence indicates that nitrification is a vital factor in crop growth and nitrous oxide emission. Nitrification and urease inhibitors have been demonstrated to be effective in inhibiting the nitrification process and are widely used as fertilizer additives in agricultural soils. However, the effects of these inhibitors on rice N uptake and N2O production through ...

Biochar Can Help to Mitigate N2O Emissions and Microbial Communities in Tea Soil
The major greenhouse gas, nitrous oxide (N2O), increases at a rate of 0.25% every year. N2O is also well known to be released in a high proportion from agricultural soil systems, thus exacerbating global warming and returning as a serious problem in agriculture.Biochar has been considered as a promising soil amendment for improving fertility and mitigating N2O emission from ...
