Abstrakt:

In 2007-2008, a plant growing pot experiment was carried out, in which the content of microelements, including heavy metals, in soil material and in compost produced by the GWDA method was found equal or less than the threshold values set by the Regulation of the Ministry of the Environment. Thus, the aim of this study was to determine the interaction between organic fertilisation and selected multi-component mineral fertilisers (SuproFoska 20, Suprofos 25 and Inmarc 4 with added urea) as well as their influence on the development of some qualitative traits of perennial rye-grass. The results showed that double doses of multi-component mineral fertilisers with urea contributed to a higher increase in the content of microelements in biomass of perennial ryegrass Lolium perenne than their single doses. The highest concentrations of cadmium, copper and lead were contained by ryegrass biomass after the application of a double dose of Inmarc 4, i.e. 9.37%, 11.0% and 2.81% more, respectively, than after the application of a single dose of SuproFoska 20 or Suprofos 25. The experiment demonstrated the highest content of cadmium, copper, manganese and lead in perennial ryegrass biomass in the treatments with combined organic (compost) and mineral (SuproFoska 20 with urea) fertilisation. However, the nickel and zinc content in biomass were the highest in the variant with combined organic (compost) and mineral (Inmarc 4 with urea) fertilisation. Multi-component mineral fertilisers and urea applied in combination with compost made of municipal sewage sludge increased the content of microelements in the biomass of cv. Stadion perennial rye-grass Lolium perenne when compared to the fertilisation objects with organic fertilisation alone.
