Agricultural lands of Ukraine are the main source of quality food. Contamination of these lands with heavy metals, pesticides and chemical residues can have fatal consequences for humanity. Soils do not have time to clean themselves from anthropogenic impact, so every year there is a decrease in yield, which will further solve the problem of food shortages.The aim of our work was to investigate the ecological condition of agricultural soils in Cherkasy region. For this purpose, the content of heavy metals (copper, zinc and lead) and macronutrients (phosphorus, nitrogen and potassium) was determined in the selected soil samples weighing 1 kg. The analysis of the soil was performed according to DSTU 4289: 2004 and DSTU 4770. 1-9: 2007. The method is based on the extraction of the mobile form of copper, zinc and lead ions from the soil with acetate- ammonium buffer solution with a pH of 4,8. In this case, part of the exchange cations passes into the solution, the compounds are hydrolyzed, acetate or ammonium complex compounds are formed. All experimental studies were performed in triplicate. The results of the study showed a general tendency to increase the copper content over the years, which ranged from 3,6 to 4,0 mg / kg. The same situation is observed for the zinc content, which from 2020 to 2021 increased by 0,1 mg / kg. But the lead content in the soil in 2019-2021 was lower by 0,3 mg / kg compared to 2018. The phosphorus content in the soil ranged from 64,3 to 65,0 mg / kg, which is positive for life. The nitrogen content in the test samples was in the range of 118,1 – 120,1 mg / kg. The potassium content in the soil was 94,2-95,3 mg / kg.
