Slag and ash dumps landscape improvement process, using organozeolitic fertilizers of the Tuff-Aln type

The invention relates to a process for stabilizing slag and ash dumps. According to the invention, the process consists of a stage of fertilization at a depth of 1 0...1 5 cm, using a fertilizer consisting of 1 0...25 t DM/ha of urban sludge stabilized with uptake of C, N, P nutrients and microorganisms and 1 ...1 .5 t DM/ha of volcanic tuff with high zeolite content, in a supported form of the Tuff­-Aln type, either solid or as 80% aqueous suspension, after which the fertilized fields are sown, in a pure culture system, with 1 00...1 50 kg/ha of leguminous and cereal crop seeds, at a depth of 3...5 cm, while maintaining and extending the stabilized surface.
