Title
Biochar Mitigates Arsenic Phytotoxicity and Improves Crop Performance in Iron‐Rich Tropical Soils

Other claims from this paper (6)
- Intervention effect In Fe-rich soil, biochar significantly mitigated arsenic-induced stress and increased potato biomass by 44%.
- Intervention effect Biochar in arsenic-contaminated iron soils improved the maximum quantum yield of Photosystem II by 39% over arsenic-only treatments.
- Intervention effect Biochar restored absolute Fv/Fm values from a severely stressed state (about 0.55) to a more physiologically stable range (about 0.76).
- Intervention effect Biochar application in agricultural soil was less effective than in the iron-rich soil.
- Recommendation The authors recommend that biochar application must be soil-specific for arsenic-affected crops.
- Observation Biochar effectiveness against arsenic phytotoxicity is highly dependent on soil mineralogy.
