Utilization of leachate for irrigation in landfill cover soil remediation projects

A landfill is constructed space on the ground to store waste, as it gradually breaks down into chemically inactive material. The landfill is filled with garbage and covered with soil or quarry. The landfill remediation operation is responsible for the restoration of the site and creates a low hill planted with native plants indigenous to the area. The aim was to study the use of leachate water from solid waste landfill sites for irrigation of plant species which normally grow in the wild. The plant species were Althea rosea, Cynodon dactylon, Inula viscosa, Melilotus officinalis and Thymbra spicata. During the two years of the study the plants were irrigated with tap and leachate water under drought conditions. After the experiment the features of the soil samples were analyzed and it was seen that using leachate water to cultivate different kinds of plants increased the percentage of total N and organic matter, and the amount of P, K, Fe and Zn in the soil.
