Аннотація: The work is devoted to the study of the expediency of using siderates for indicators of the agro-ecological state of the soil in the conditions of modern intensive crop rotation. Fertility indicators and soil contamination with heavy metals were studied. Correlationregression dependencies between the studied factors were established and calculated. The purpose. Study of the siderates on the agro-ecological condition of the soil. Result. It was established that the biological mass of siderates, worked into the soil, helps to increase the content of humus by 0.11-0.14%, alkaline hydrolyzed nitrogen – by 1.7-7.1%, exchangeable potassium – by 27.4-32.2%. The highest content of humus in the soil is provided by siderates of peas and winter rapeseed – 2.44% each, alkaline hydrolyzed nitrogen – 127 mg/kg – peas, mobile phosphorus – 520 mg/kg – winter wheat, exchangeable potassium – 230 mg/kg – winter rapeseed, the largest amount of absorbed bases – 16.8 mg-eq./100 g – peas, the lowest hydrolytic acidity – 1.60 mg-eq./100 g – winter wheat, the highest pH value 5.85 – spring barley. Value/originality. It was determined that the cultivation of siderates leads to an increase in the content of mobile heavy metals in the soil by 17.2-24.3%, cadmium – by 10.0-14.3%, copper – by 17.6-22.2%, zinc – by 34.7-39.9%, compared to the version without siderates. Among the studied siderates, the lowest content of lead in the soil – 1.28 mg/kg and cadmium – 0.20 mg/kg is provided by winter rapeseed; copper – 0.51 mg/kg – peas and winter rapeseed; zinc – 1.73 mg/kg – spring barley.
