Abstract
Leachate from waste disposal site often contains refractory organic compound and/or high concentrations of nitrogen and salts. In this paper, the leachate application experiments were performed to investigate the availability of soil-turf filter system for advanced treatment, and the effects of the leachate irrigation on the growth of turfgrass (Zoysia matrella Merr.) was studied. As the application rate increased from 3 to 20mm/day, the biomass yield of Z. matrella increased. It was concluded that Z. matrella possessed superior salt tolarance. However, the nitrogen uptake of Z. matrella was inhibited when the chloride (Cl-) concentration was over 5000mg/l, and when Cl- concentration was beyond 10000mg/l, the growth rate decreased to half of the no chloride addition experimental run.
