The object of this study was Gumavit, a liquid humic fertilizer based on peat. This fertilizer is obtained by cavitation dispergation of peat in a shock pulse generator and subsequent alkaline extraction from a water-peat mixture of humic acids. This study examined the effect of Gumavit on the germination energy and germination capacity of barley seeds, wheat and tomatoes, as well as its effect on plant growth and development. It was found that Gumavit did not adversely affect the germination energy and germination capacity of seeds of grain crops and tomatoes. The use of a 0.2% (of humic acids - HA) Gumavit solution had a positive effect on the sowing quality of the studied cultures’ seeds. The use of a 0.01% (of HA) solution of Gumavit to moisten sand and germinate seeds after 14 days had a positive effect on the length and mass of Favorit wheat grain sprouts; as well as a positive effect on the root mass of Favorit and Kamyshanka-3 wheat, Volgogradskii-12 barley, Volgogradskii 5/95 tomatoes and Dar Zavolzhia tomatoes. The increase in the root mass of the studied cultures can be explained by the absorption of a small fraction of humic substances by the roots of these plants, leading to an increase in the number of lateral roots and their root hairs.
