Abstract:
In the experiment being carried out, the effect of granular fertilisers being produced from industrial waste products, i.e. CaSO4?2H2O (waste product in production of multicomponent mineral fertilisers), FeSO4?7H2O (waste product in production of titanium dioxide), coniferous and deciduous sawdust mixture, and municipal sewage sludge with addition of mineral fertilisers on cadmium, copper, chromium, nickel, lead and zinc contents in spring rape seeds and spring triticale grain. The results being obtained show that the granular fertilisers being tested did not increase the content of heavy metals (Cd, Cu, Cr, Ni, Pb and Zn) in test plants above the acceptable standards. In most fertilisation objects treatments with these granular fertilisers, differences between the content of respective heavy metals in test plants were not significant. The increasing doses of granular fertilisers in most fertilisation objects did not have any significant effect on the increase in the content...
