The efficiency of landfill leachate evapotranspiration in soil-plant system with reed Phragmites australis

The effectiveness of leachate evapotranspiration from soil-plant systems with reed Phragmites australis was investigated within two years period. Significant linear dependence between reed biomass growth and transpiration was observed. It was revealed that cumulative curves of evaporation and evapotranspiration were linear and estimated models were well fitted to the experimental dates. Daily evapotranspiration was in the range from 1.01 to 3.15 mm d−1 in the first year of research and from 2.68 to 4.94 mm d−1 in the second year. It indicates the usefulness of soil-plant systems with reed in landfill leachate treatment by vaporization. Additionally, the research showed that the application of sewage sludge into the soil caused the increase in the vaporization efficiency.
