Properties of hymatomelanic acid peat and its influence on the growth processes of spring wheat varieties Iren

In this paper, we consider two ways for obtaining hymatomelanic acid extraction into conventional Soxhlet extractions: directly from the peat and from the dry product of humic acid. The results of the study of the elemental composition of humic and hymatomelanic acids are presented, their similarities and differences are analyzed. In order to study the effect of humic and hymatomelanic acid preparations on the growth processes of spring wheat, a vegetation experiment was conducted. Peculiarities of biological action of the solutions and hymatomelanic and humic acids of different concentrations in spring wheat varieties “IREN” were investigated. The paper presents a method for determining the ash content of the studied peat, as well as, calculations of the economic feasibility of using preparations based on the hymatomelanic acids.
