Summary: Analysis of soil contamination with heavy metals showed that the concentration was lead – 2.52 mg/kg, cadmium – 0.22, zinc and copper – 3.53 mg/kg in the field crop rotation, forest plantations – 1.20 mg/kg, 0.12, 4.30 and 2.27 mg/kg, respectively. The use of organic fertilizers reduces lead honey by 1.11 times in soil, cadmium by 2.75, zinc by 1.42 and copper by 1.42 times, respectively. The use of microfertilizers reduced the intensity of contamination of melliferous with heavy metals, namely, lead – by 2.31 times, cadmium – by 11 times, zinc – 1.42 and copper – by 1.25 times. The intensity of soil contamination was reduced by the introduction of lead residue – by 3.2 times, cadmium – by 2.75 times, zinc – by 1.25 and copper – by 1.42 times. It is also necessary to note a decrease in the intensity of soil contamination of agricultural honey plants by heavy metals for the use of siderates, in particular lead – by 3.15 times, cadmium, zinc, copper, 2.44, 2.9 and 1.8 times compared to similar indicators on soils without fertilizer. The use of green manure resulted in a 3.15, 2.44, 2.9 and 1.8-fold reduction in the intensity of soil pollution of agricultural land with lead, cadmium, zinc and copper compared to the same indicators on soils without fertilisation. When using manure, the efficiency of lead reduction was 2.8 times lower compared to organic fertilisers, 1.4 times lower for microfertilisers, and 1.03 times lower for green manure. When using microfertilisers, the effectiveness of cadmium reduction was 4 times lower compared to the use of organic fertilisers and manure, and the use of green manure was 4.5 times lower. The effectiveness of zinc reduction in the soil with the use of green manure was 2.3 times lower compared to the use of manure, microfertilisers and organic fertilisers, and the effectiveness of copper reduction with the use of green manure was 1.2 times lower compared to the application of manure and organic fertilisers, and 1.4 times lower compared to the use of microfertilisers.
