چکیده
The studies on the use of municipal wastewater sludge as an unconventional chemical ameliorant with a fertilizing effect were carried out ore dressing waste ("tailings") apatite-nepheline plant ANOF-2 KF JSC "Apatit" predominance nepheline sands in their composition. tailings dump is included list objects accumulated environmental damage region, but due to its rich mineral composition, it recognized technogenic deposit subject conservation for prospect obtaining apatite, nepheline, sphene, aegirine and titanomagnetite concentrates. In work, method phytotesting soil irrigated unfiltered rainwater fragmentary application sewage regional treatment enterprise has been applied. experiments have single-species seed recommended reclamation disturbed territories northern regions. During formation sown phytocenosis from meadow timothy ( Phleum pratense L.) sands, stimulating nutrient regime confirmed. After phytoextraction (at end experiment), retains high residual pool basic nutrients (N, P, K), which indicates prolonged action sludge. To confirm obtained laboratory conditions, field experiment laid at reserve tailing 2019, observations are continuing.
