- Title
Impact of Ectomycorrhizal Colonization of Hybrid Poplar on the Remediation of Diesel-Contaminated Soil.

- Abstract
This article discusses the effects of ectomycorrhizal fungal treatment on root growth of hybrid poplar trees in diesel contaminated soil. According to the authors, poplar fine root production in diesel contaminated soils increased and hybrid poplar leaf nitrogen and phosphorus concentrations were significantly greater. However, significantly greater concentrations of total petroleum hydrocarbons (TPH) were found sequestered in hybrid poplar root/fungal-sheath complexes from the colonized treatment compared to the roots of the uncolonized treatment. They conclude that fungal colonization increased biomass, but inhibited removal of TPH from the soil.
