EVALUATION OF REMOVAL OF HEAVY METALS WITH PHYTOMASS ANNUAL HERBS WHEN USING VARIOUS FERTILIZER SYSTEMS
Abstract
Under the conditions of a lysimetric experiment on podzolic chernozem, it was found that the use of dolomite flour contributed to a decrease in the mobility of metals and their translocation into crop products, which was reflected in a decrease in their removal relative to the background. The use of mineral fertilizers by increasing the yield of phytomass contributed to an increase in the removal of copper, zinc, lead and cadmium from the soil. The largest total removal of copper, zinc, lead and cadmium with the phytomass of annual grasses (8,035 mg/m2) is observed when using a mineral fertilizer system, and the smallest removal of the indicated metals is observed when using lime without manure (5,092 mg/m2).
