• 【约稿】Researchers Uncover Rising Arsenic Levels in Chinese Soils

    China faces widespread soil arsenic pollution caused by intensifed industrial and agricultural activities, the impacts of which, however, have never been evaluated at the national scale.
      A team led by Researcher LUO Yongming from the Soil and Agricultural Sustainability Key Laboratory of the Institute of Soil Science, Chinese Academy of Sciences (ISSCAS), along with their collaborators, have made significant advancements in understanding arsenic contamination in China’s...

  • Nitrogen-loss and carbon-footprint reduction by plant-rhizosphere exudates

    Since the Green Revolution in the 1960s, mineral N fertilizers have been a key factor in boosting crop yields and feeding a growing population. Low-carbon approaches to agriculture constitute a pivotal measure to address the challenge of global climate change. In agroecosystems, rhizosphere exudates are significantly involved in regulating the nitrogen (N) cycle and facilitating belowground chemical communication between plants and s...

  • Emerging Contaminants: A One Health Perspective

    Industrialization brought about significant changes in pollution patterns, introducing new contaminants into the environment such as heavy metals, industrial chemicals, and particulate matter. The rise in environmental pollution is driven by rapid global development, which often prioritizes human needs over the health of the planet. Despite efforts to control legacy pollutants, the continual introduction of new substances poses a significant threat to both people and the environmen...

  • Saline–alkali land reclamation boosts topsoil carbon storage by preferentially accumulating plant-derived carbon

    Saline–alkali land is an important cultivated land reserve resource for meeting the challenge of feeding the increasing global human population. Saline–alkali land is an important cultivated land reserve resource for tackling global climate change and ensuring food security, partly because it can store large amounts of carbon (C). However, it is unclear how saline–alkali land reclamation (converting saline–alkali land into cultivat...

  • Size, distribution, and vulnerability of the global soil inorganic carbon

    Soil inorganic carbon (SIC) (supplementary materials, soil carbonate system) is conventionally viewed as a relatively stable carbon pool with an assumed turnover time of millennia. This view is shifting as evidence of accelerated SIC dynamics is growing, revealing substantial perturbations to...Global estimates of the size, distribution, and vulnerability of soil inorganic carbon (SIC) remain largely unquantified. By compiling 223,593 field-based measurements and developing machine-learning models, Prof. ZHANG Ganlin from the ISSCAS and his team report that global soils store 2305 ...

  • Legume rhizodeposition promotes nitrogen fixation by soil microbiota under crop diversification

    Recent field studies on chemical feedbacks between plant species have focused more on non-kin species defense, and less on how chemical cues may alter the rhizomicrobiome and microbially mediated functions that affect the plant fitness of the species involved.Biological nitrogen fixation by free-living bacteria and rhizobial symbiosis with legumes plays a key role in sustainable crop production. Here, associate professor CHEN Yan and his team study how different crop combinations influence the interaction between peanut plants and their rhizospher...
