SLAG AND ASH DUMPS LANDSCAPE IMPROVEMENT PROCESS, USING ORGANO-ZEOLITIC FERTILIZERS OF THE TUFF-ALN TYPE

摘要

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 10...15 cm, using a fertilizer consisting of 10...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 100...150 kg/ha of leguminous and cereal crop seeds, at a depth of 3...5 cm, while maintaining and extending the stabilized surface.
