INFLUENCE OF POST-CHAMPIGNON SUBSOIL FERTILIZATION ON LEAD, CADMIUM, AND NICKEL CONTENTS IN ITALIAN RYEGRASS

摘要

The influence of post-champignon subsoil fertilization as well as nutrition with only and completed mineral potassium-nitrogen fertilizers, and manure (standard) on lead, cadmium, and nickel contents at yields of Italian rye-grass was evaluated in two-year pot experiment. More lead and cadmium, while less nickel was recorded at ryegrass harvested from objects fertilized with only post-champignon subsoil as well as with mineral fertilizers addition as compared to objects treated with only manure. In most cases, concentration of the heavy metals studied showed a significant differentiation depending on the fertilization type.
