- •
Effect of biochar on phytoavailability of heavy metal in alkaline soil was studied.
- •
Ash in biochar probably had a positive role in chemical extractability of heavy metal.
- •
Biochar significantly reduced phytoavailability of most heavy metals to ryegrass.
- •
Chemical extractability failed to assess metal phytoavailability in soil with biochar.
- •
Biochar produced at lower temperature was recommended for remediation of similar soil.
