Abstract
Laboratory chronic experiments have determined the effect of the content of petroleum products (PP) in reclaimed alluvial turf heavy loamy and light loamy soil on the growth, yield of green mass and the development of the root system of spring wheat and seed peas. High residual PP content in reclaimed soil resulted in increased seed germination time, with no effect on germination. When growing wheat on reclaimed alluvial turf heavy loamy soil, the toxic effect was manifested only in the early stages of plant development in a variant containing 16.9 g/kg of PP. In the alluvial turf light loamy soil version containing 21.8 g/kg of pollutant, inhibition of plant growth was observed throughout the experiment. In chronic experiments for growing peas on heavy coal soil containing 16.9 g/kg of PP, on light coal soil containing 11.7 g/kg and higher, plant growth inhibition was observed, with a tendency to increase the toxic effect towards the end of the growing experience. Oil contaminants in concentration up to 11-12 g/kg in reclaimed alluvial turf heavy and light-coal soils do not affect the yield of green wheat mass, in concentration 9.7 g/kg and higher inhibit the growth of pea plants, lead to a decrease in the yield of their green mass. The oxidation efficiency of petroleum products when growing plants on reclaimed alluvial turf soil did not exceed 37% and was determined by the initial concentration of pollutant. The presence of PP in the soil led to a change in the structure of the root system of the plants being grown. Tested plants when cultivated on heavy soils are more resistant to negative PP. The findings show that sown peas are more sensitive to the presence of PP in reclaimed soil.
