Effectiveness of different meliorants to reduce the degree of heavy metal mobility in polluted agrozem

Abstract

Various meliorants are shown to reduce the degree of lead and cadmium mobility in polluted agrozem by 20–60% on average. Sodium sulfide and superphosphate at doses of 120 kg of active ingredient per/ha (a.i./ha) and phosphorite meal at a dose of 1.5 t/ha somewhat stand apart in the effectiveness of this action.
