Biochar Softened a Two-Pollutant Soil Stress
One percent biochar reduced earthworm avoidance in soils containing copper and commercial glyphosate.
Summary
One percent biochar reduced earthworm avoidance in soils containing copper and commercial glyphosate.
In laboratory soil tests, combined copper and glyphosate produced avoidance as high as 100 percent. Adding one percent biochar lowered avoidance by roughly 27 to 29 percent. The earthworm response is an ecological indicator, not proof of full detoxification or field-scale remediation.
Why it matters
One percent biochar reduced earthworm avoidance in soils containing copper and commercial glyphosate.
Limits and context
- In laboratory soil tests, combined copper and glyphosate produced avoidance as high as 100 percent.
- The earthworm response is an ecological indicator, not proof of full detoxification or field-scale remediation.
