Zerebna L. Influence of high levels of pollution by lead and cadmium of podzolic and typical chernozems on entering of these elements in plants of barley and corn, a yield and its quality in Left-bank Forest-steppe of Ukraine

Object - processes of transport of heavy metals, macroelements and microelements from soil to crops. The purpose - to determine a role of mineral fertilizers, lime and sorbents- ameliorants in reduction of lead and cadmium transport to generative organs of barley and maize plants at high levels of their contents in typical and podzolic chernozems. Methods - general scientific and special. Theoretical results - influence of high levels of typical and podzolic chernozems pollution by lead and cadmium on transport of elements- pollutants, macro- and microelements to plants of barley and maize is determined. Practical results - measures on reduction of heavy metals' transport to plants of barley and maize at high levels of soil pollution by lead and cadmium are carried out. Novelty - appropriatenesses of lead and cadmium, macro- and microelements transport to plants of barley and maize, an influence to yield and its quality are determined. Threshold levels of chernozem typical pollution by lead are fixed,with exceeding of which ability of barley plants against action of lead stops. The degree of introduction - necessity of local application of mineral fertilizers and lime in agroenterprises located in zones of technogenous emissions influence is proved. Sphere - an agricultural production.
