Abstract

An effect of ashes on crops and element uptake by meadow fescue was examined with pot experiments. The experiments were carried out by using soil composed of loose sand and ash-slag mixture originated from hard coal combustion. The experiments were conducted in four replications in polyethylene pots filled with mineral soil and furnace ash. In the experiment the ash was applied at 23.33 g ·pot-1 corresponding to 20 t ·ha-1 and increasing cupper doses. The experiment scheme included also a control containing a mineral soil and ash only. The meadow fescue vegetation period was fixed ay 60 and 75 days. The element content in plant material after dry mineralization was determined by using the ICP-AES method (inductively coupled plasma). It was found that the furnace ash applied only led to considerably reduced crop of meadow fescue. Due to increasing cadmium doses mixed with ash an decreasing content of Zn, Pb, Ni and increasing Cr, Cu, Cd content was observed. When estimating the content of chromium, lead, cooper and nickel in fescue with reference to the IUNG-PIB values, it was found that it meets the good quality feed standarts. A regards zinc and cadmium contents it was found that the allowable abundance of those elements was exceeded.
