abstract:
Much lower quantities of farmyard manure used for soil fertilization and relatively small amounts of mineral fertilizers enriched with microelements applied in agriculture create great opportunities for the use of composts for fertilizing soils and crops. Presented research aimed at determining the direct and consequent effect of composts based on green wastes in comparison with traditional mineral (NPK) and organic (FYM) fertilization on the accumulation of selected microelements in oat biomass and their bio-availability from soil. The largest amounts of microelements taken up by oat (irrespective of the plant part) were registered in mineral treatment, which was determined mainly by the highest oat biomass yield. Microelement quantities absorbed by oats in compost treatments were on a level comparable to the amounts taken up from the farmyard manure treatment. Concentrations of assimilable microelement forms in soil increased after three years of research, which among others was caused by proceeding soil acidification.
