IMPACT OF POLLUTANTS IN THE SOIL OF THE AGROLANDSCAPE OF THE RECULTIVATED LANDFILL ON CROPS

Abstract

After recultivation of municipal solid waste (MSW) landfills using sewage sludge, such landfills should become environmentally sustainable and productive agricultural landscapes. Sewage sludge significantly impacts the productivity of the newly created agricultural landscape and the quality of agricultural products when creating the arable layer of the recultivated MSW landfill. The research aims to study and analyze the influence of heavy metals and arsenic in the soil of the recultivated landfill on the yield and quality of agricultural products. Perennial grasses on the reclaimed landfill are forced to adapt to adverse environmental conditions, which leads to a loss of plant resistance. The research was required due to the presence of heavy metals and other pollutants in the soil, which negatively impact agricultural products and their quality and are also associated with a wide range of physiological and biochemical changes in plants. The results of the chemical analysis of Triticosecale, Bromus inermis Leyss, and Festulolium showed low levels of mercury, cadmium, lead, arsenic, copper, and zinc, as well as their suitability for feed. Physico-chemical analysis showed that the most significant amount of crude protein (27.5 g/kg) from the studied samples is contained in Bromus inermis Leyss, crude fiber – in Triticosecale (Option 3) (35.04 g/kg), crude ash – in Festulolium (Option 3) (11.7 g/kg).
