Supporting evidence — 8 representative gaps

• Light grazing enhances microbial-mediated nitrogen transformation in desert steppe soils (2025) · BMC Plant Biology · cited 7× · doi

  AIMS: Soil microorganisms play a central role in nitrogen transformation and availability, yet their regulatory functions in mediating nitrogen transfer between soil and plants under long-term grazing remain poorly understood.

• Rice straw increases microbial nitrogen fixation, bacterial and nifH genes abundance with the change of land use types (2024) · Frontiers in Microbiology · cited 13× · doi

  Previous studies have focused on the effects of carbon and nitrogen addition on a single type of soil, but the response of soil microorganisms to varying carbon and nitrogen inputs under different land soil use types have been relatively understudied, leaving a gap in our understanding of the key influencing factors.

• Rainfall Shapes the Diversity of Soil Nitrogen‐Fixing Microorganisms Worldwide (2026) · Advanced Science · doi

  ABSTRACT Soil nitrogen‐fixing microorganisms naturally fertilize terrestrial ecosystems, but the primary driver of their diversity across the globe and the underlying mechanisms remain unclear.

• Carbon availability mediates differences in rhizosphere denitrification potential between intercropped plants (2026) · Frontiers in Sustainable Food Systems · cited 1× · doi

  Further research is needed to understand how the rhizosphere effect on denitrification varies between different plant species and communities. Studies should investigate the role of other potential drivers of denitrification, such as anaerobicity. Research should focus on developing strategies to manage ecosystems to produce less N2O.
