AP19576993 " Intensification of the process of recultivation of disturbed lands during open-pit mining due to hyperaccumulative plants and mycorrhizae"

Relevance

Open-pit mining leads to soil degradation and heavy metal pollution. Effective reclamation using mycorrhiza and hyper-accumulator plants accelerates the restoration of soil cover and reduces pollution, which is especially important for arid regions. The introduction of such methods contributes to environmental rehabilitation and further economic use of disturbed lands.

Purpose

The aim is to intensify the process of recultivation of heavy metal-contaminated and eroded soils of disturbed lands during open-pit mining, based on a comprehensive analysis of the state of soils and vegetation, as well as the use of mycorrhiza and hyperaccumulative plants.

Expected and achieved results

Field and laboratory experiments have been conducted on the reclamation of lands that have become unusable in this area. The soil was sifted from the territory where technical reclamation was carried out, with a study of its pH, constant permeability, maximum moisture, organic fertilizer, nitrogen, phosphorus and potassium content. A comprehensive analysis was carried out for the presence of heavy metals in samples of disturbed lands by atomic absorption spectrometry. To study the effect of mycorrhizal and hyper-accumulative vegetation on intensive land reclamation at industrial facilities based on the results of chemical analysis and experiments to detect heavy metals in the soil. Monitoring of the degree of restoration with and without the use of hyperaccumulative plants and mycorrhiza at the research site during the restoration of disturbed areas during open-pit mining.
