Sažetak
The use of organic waste products (OWP) on agricultural soils may have numerous benefits, but certain concerns regarding nutrient fluxes (N, P) or increased inputs of toxic elements (Cd) are also present. Previous research showed that compost amendments may affect more the availability than the total element concentration in the soil, thus the aim of study was to evaluate the effects of a long- term urban waste composts application started in 1998 on soil element availability to plants. Element composition of wheat and maize (straw and grain) grown on four experimental plots amended with 3 composts (sewage sludge with green waste and wood chips - SGW, fermentable organic waste with green waste - BIO, municipal waste after selective sorting - MSW) and a farmyard manure - FYM, were compared to the element composition of plants grown on a control plot receiving only nitrogen mineral fertilizer (CTR), for the period 2008-2013. Significantly lower N, P, K and S concentrations and higher Cd and Mn concentrations were periodically recorded in straw and/or grain of wheat grown in CTR plot compared to wheat grown in OWP amended plots. Lower Mo concentration was repeatedly recorded in maize grown in CTR plot (straw and grain). Data suggest that the OWP application may affect certain major and/or trace element soil availability to plants, but their phytoavailability also showed differences between the years and/or cultivated crop.
