Features of the Accumulation of Heavy Metals in Chernozem on the Background of Increased Mineral Nutrition

Abstract

The paper presents the results of a study of the content of copper, zinc, lead and cadmium in podzolized chernozem using agromeliorative techniques obtained in a model lysimetric experiment when growing annual grasses. The calculation of the values of the total indicator of soil pollution with heavy metals showed that its lowest value (0,52) was achieved in option 4 with the complex use of ameliorants (manure and lime) against an increased background of mineral fertilizers and in option 3 with the use of manure against an increased background of mineral fertilizers (0,62).
