METHOD FOR INTENSIFYING THE RECLAMATION SUCCESSION OF LANDS CONTAMINATED WITH HEAVY METALS Russian patent published in 2023 - IPC B09C1/00 A01B79/00 

FIELD: agriculture.

SUBSTANCE: invention relates to a method for intensifying the reclamation succession of lands contaminated with heavy metals by introducing an organo-mineral substrate into them, consisting of frozen lignin-containing residues of the pulp and paper industry (sludge-lignin) and ashes from burning wood fuel. The method includes introducing an organo-mineral substrate into disturbed lands contaminated with heavy metals, consisting of frozen sediments of lignin sludge and wood fuel combustion ash, to intensify reclamation succession by introducing optimal amounts of plant nutrients (organic matter, potassium, phosphorus, nitrogen) and immobilization of heavy metals. The method is carried out by adding an additive, which is wood fuel combustion ash, to the frozen sediments of lignin sludge in a ratio of 1:0.05, followed by mixing and adding 30 t/ha to disturbed lands contaminated with heavy metals to intensify reclamation succession.

EFFECT: intensified processes of reclamation succession of disturbed lands contaminated with heavy metals.
