- Abstract
- The article presents the results of a study of the effect of metallurgical slags on morphometric parameters and phytotoxicity of the soil during the cultivation of soybeans of the Duar variety (Glycine max (L.) Merr.). The effects of various slag concentrations have been studied in the laboratory. (from 0 to 10 %) on the growth and development of soybean seedlings. It was found that at a slag concentration of 1 %, the maximum stimulating effect was observed: the length of the stem increased by 61.4 %, the length of the root by 16.2 %, and the crude biomass by 54.9 % compared with the control. The phytotoxicity index at this concentration was T = -0.20, which corresponds to a strong stimulation of plant growth. With increasing slag concentration, the stimulating effect weakened, and at a concentration of 10 %, weak phytotoxicity was noted (T = 0.05). It was revealed that metallurgical slags in low concentrations (1-2.5 %) have a stimulating effect on plant growth due to improved mineral nutrition, while high concentrations (>7.5 %) can exhibit a phytotoxic effect. The results obtained are of practical importance for optimizing technologies for the use of metallurgical waste in agriculture and phytoremediation.
