Other claims from this paper (8)
- Intervention effect Fermented cow dung at 0.5% to 2.0% did not significantly change AMF infection rate.
- Intervention effect Fermented cow dung promoted alfalfa growth.
- Intervention effect PAH residues were lower after 1.0% and 2.0% fermented cow dung than in controls.
- Intervention effect Papermaking sludge at 0.05% and 0.1% increased AMF infection rate and plant biomass.
- Intervention effect The 0.2% sludge treatment had a negative effect.
- Intervention effect Three-, four- and five-ring PAH degradation rates exceeded controls.
- Association Soil PAH degradation rate was linearly related to AMF infection rate in roots.
- Recommendation The authors suggest small amounts of sludge as a stimulant in mycorrhizoremediation.
