Research was conducted on the territory of the workshop for the production of sulfuric acid, which is located on the industrial site of “NEOHIM” JSC, Dimitrovgrad.
The site area was found to be characterized by heavy metal content exceeding the upper threshold requirements of the Dutch Soil and Groundwater Standard List for copper.
Measures are foreseen to overcome the unfavorable characteristics of the soils, which include the following:
– site clearance;
– liming of the site;
– filling the cleared areas with geological materials from the “Novi Rudnitsi” region, which are characterized by a sandy-clay mechanical composition, a neutral reaction to the environment and a low supply of the main nutritional elements for plants – nitrogen, phosphorus and potassium;
– spreading a layer of humus materials with a thickness of 40 cm;
– weeding, which will be done by sowing grass mixtures.
