Accumulation of Chemical Elements in the Vegetative Mass of Energy Cultures Grown on Gray Forest Soils in the Western Forest Steppe of Ukraine

Abstract

Today, energy crops that are undemanding to soil fertility are increasingly used for the production of biofuel, electricity, and heat. Favorable climate, large areas of agricultural lands of Ukraine create the necessary conditions for growing the most popular energy crops, which will be able to supply the domestic market, as well as export. The article is aimed at studying the accumulation of chemical elements phosphorus (Р), potassium (K), copper (Сu), zinc (Zn), cadmium (Cd), lead (Pb) in the vegetative mass of Miscanthus, Silphium perfoliatum L. and Sida hermaphrodita L. Rusby for their cultivation in the conditions of the Western Forest Steppe of Ukraine on gray forest soils. The article presents the results of own field and laboratory research.
