Abstract
- The annual application of fertilizers with nitrogen, phosphorus and potassium to wheat and maize cultures leads to an increase the concentration of heavy metals in their seeds. For this purpose,during the period 2010-2012, was studiedthe effect of application of different doses of chemical fertilizers on the lead concentration of wheat and maize grains. The results showed that with the gradual increase of the chemical fertilizer doses, the lead concentration of the cereal grains also increased. Statistically significant differences from the nonfertilized control were recorded for both grains, 0.046 mg/kg for wheat seeds and 0.059 mg/kg for maize grains respectively, in variant fertilized with N160P80K120. Lead concentrations did not exceed the maximum permitted limit of 0.2 mg Pb/kg, according to ORDER (EC) No. 1881/2006. [ABSTRACT FROM AUTHOR]
