The purpose of this study is to develop agrotechnological methods of establishing and controlling the content of heavy metals in plant products. For laboratory experiments we used the typical black soil. The results of lead and copper in soil and plants of spring wheat variety Kinelskaya 59, with different levels of pollution in the conditions of a pot experiment. It is established that with the increase of applied doses of salts of heavy metals increases their content in soil and spring wheat seedlings. The percentage of mobility in the soil of copper and lead in the soil increases with the pollution level 2.9 times and 9.2 times, respectively. With increasing doses of copper and lead increases the concentration of plant-available forms of nitrogen and phosphorus. For all variants of experience is typical acropetal distribution of heavy metals in plants – copper: the roots (46.59) > shoots (of 14.66); lead: the roots (47.0) > shoots (12.78). The value of Iа decreases with increasing dose of applied salt that is indicative of the culture of spring wheat variety Kinelskaya 59 barrier. High correlation observed between the content of copper in plant roots and gross values (r = 0.98) and mobile forms(r = 0.94) in the soil. The value of copper in the shoots of plants are weaker related to the content of the element in the soil (r = 0.66). Between the content of gross and mobile forms of lead in soil revealed a high correlation (r = 1.00), the same value when item is marked with the plant roots and shoots.
