The composting is one of the most effective recycling method of green waste. The presence of some heavy metals, such as chromium, copper, manganese and zinc may influence the compost quality. The bioavailable and unavailable metal forms for plants determined by sequential analysis showed similarities in relation to the percentages of extracted forms. The lowest percentages were recorded for the bioavailable metal forms for plants uptake. Thus, the succession F6>F5>F4>F3>(F1+F2) is characteristic for chromium, the succession F5>F6>F4>F3>(F1+F2) is characteristic for copper and zinc and the succession F5>F4>F6>F3>(F1+F2) is characteristic to the zinc and manganese. Thus, by adding some organic additives, like manure, the micronutrients and heavy metals regime is influenced.
