Abstract

Today, the study of the effects of dust and gaseous pollutants in the soil as a result of the cement industry, the justification of changes in their properties, the creation of appropriate reclamation technologies is an urgent issue. In the study area, the main source of soil contamination under the influence of the cement industry is dust. The dust mainly spread around the cement plant to a radius of 5,000 meters, causing the soils to become mostly polluted. In the morphological observation of the cross-sections taken by the soil samples, it was mainly influenced by the change in soil colour in the soil surface layer. The chemical and physical properties of the soil change under the influence of pollution, including the tendency to increase the amount of humus as it moves away from the object of study in a wavy pattern. The pH of the soil changed alkalinity. Changes in the agrochemical and other properties of the soil as a result of the cement industry adversely affected the vegetative development of the agricultural plants grown on it, disrupting the growing season and photosynthesis processes and resulting in reduced yields.
