Supporting evidence — 8 representative gaps

• Elevated CO2 and warming intensify plant reliance on soil nitrogen reserves despite intensive fertilization (2026) · Nature Communications · doi

  Future research should investigate the effects of climate change on soil nitrogen cycling in different ecosystems. Studies should examine the potential for compensatory biological nitrogen fixation to offset soil nitrogen depletion. Research should also explore new strategies to maintain soil nitrogen stocks and ensure the long-term sustainability of intensively managed agroecosystems.
