Abstract
The samples of humic preparations (HP) containing macro- and microelements of plant nutrition were obtained on the basis of humic acids (HA) isolated from brown coal of the Tisul deposit of the Kansk-Achinsk coal basin. The biological activity of humic preparations was tested under laboratory and field conditions on stony and loamy soils using the seeds of high-quality wheat varieties ‘Iren’ and ‘Novosibirskaya 89’. A comparative assessment of the influence of the content of microelements cobalt, manganese, copper and zinc in humic preparations on the growth parameters of wheat was carried out. It is shown that the effectiveness of the use of humic preparations depends on the concentrations of all components, the method of their introduction, as well as on the edaphic properties of soil substrates.
