The results of studying of the maintenance of lead and cadmium in soil and agricultural crops at use of various agrotechnologies are presented in the article. The negative tendency of accumulation of heavy metals in winter wheat grain is noted
In the article we consider the influence of agricultural
technologies of cultivation of winter crops on
existence of various forms of heavy metals in an arable
layer of earth in the conditions and their accumulation
in grain production. The gross content of compounds
of copper in an arable layer of black leached soil is
above background values (maximum concentration
limit 1,5-1,7), a share of the fixed connections makes
75 %. The gross content of zinc exceeds background
value for chernozems (1,25 clark). The correlation of
the water mode of the soil and the content of mobile
compounds of heavy metals in an arable layer - a
straight line for Cu and the return for Mn , Pb, Cd and
Co. Supplement of an arable layer of earth with mobile
forms of copper, zinc and cobalt low, manganese -
corresponds to the average level. Speaking of the
degree of actual mobility the studied elements settle
down in sequence: Cd> Mn> Co> Pb> Zn> Cu.
Degree of potential availability decreases among:
Zn> Mn>Pb> Co> Cu. The existence of Mn,
Cu, Zn and Co in grain of wheat is lower than
maximum concentration limit, and accumulation of
Pb and Cd is higher than maximum concentration limit
in grain production for baby food for 10-15 %, that
increases individual risk of death to the maximum
permissible level
