The 1st to 18th year changes in the easily soluble element contents (NH4-acetate + EDTA) were investigated in the ploughed layer of a long-term heavy metal load field trial, set up on a Mezőföld calcareous chernozem soil in Hungary, in Spring 1991. The thirteen potentially harmful elements (Al, As, Ba, Cd, Cr, Cu, Hg, Mo, Ni, Pb, Se, Sr, Zn) were applied at the beginning of the experiment in soluble salt forms, in 0/30, 90, 270, 810 kg. ha-1 element doses. The easily soluble element contents decreased sharply in the first years, which was followed by an equilibrium at a low concentration level. Cadmium was the only exception, which element, even in the 18th year after application, showed equilibrium at relatively high, around 100 mg. kg-1 LE-Cd level. Soil analyses were accompanied by young plant analyses, as well as main product and byproduct harvested crop analyses. In certain years, household animal feeding experiments were also carried out for investigating the behaviour of the heavy metals in the food chain.
