Utilization of result of trial seeding experimental plots in the course of rehabilitation of central tailing heap of Ján ?verma mine in ?aclé?

摘要

The contribution contains results of trial seeding with application of various fertilizers and soil conditioners. A procedure for the recovery of land of the heap is presented, which includes ground shaping to achieve stability and to prevent water from uncontrolled running down during prolonged or heavy rains in the area and biorehabilitation to cover the heap with vegetation, i.e. to bind the surface by crops able to grow on the heap. On the basis of knowledge of specific properties of the site, a grass mixture for extensive non-agricultural utilization was proposed for the model experiment.
