Assessment of the effect of liming and fertilizers on the content of heavy metals in leached agrochernozem and accumulation in spring wheat grain

Abstract

Relevance. In modern conditions, the issues of soil protection from heavy metal pollution attract the increased attention of researchers from different countries. This problem is especially acute for agricultural landscapes located near cities, industrial facilities and highways.Methods. The objects of research were the soils of agricultural landscapes of the Ufa district of the Republic of Bashkortostan. The studies were carried out on leached chernozem.Results. According to the data obtained, the content of heavy metals in soils and in spring wheat grain varies within the limits not exceeding the MPC level. When using mineral fertilizers in agrochernozem, there is a tendency to increase the content of mobile forms of heavy metals and their accumulation in spring wheat grain. Liming, application of manure and siderate contributed to a decrease in the content of heavy metals in the soil and a decrease in their intake into the grain of spring wheat. This indicates the possibility of directed regulation of grain quality by the use of agro-reclamation and agrotechnical techniques.
