• Dual effects of soil conditioners on wheat yield and soil properties in southern henan (2026) · Scientific Reports · doi

  This study had a two-year experiment period, which is insufficient to capture the long-term effects of conditioners (e.g., biochar, microbial fertilizer) on soil carbon pools and microbial communities. Moreover, the study focused only on wheat without incorporating the typical wheat–maize rotation system in southern Henan, limiting the generalizability of the conclusions. Future studies should implement long-term field experiments, include the rotation system, and expand to more regions and soil types to further validate the applicability of the conditioners, thereby enhancing the scientific rigor and generalizability of the findings.
