Почва как связующее звено функционирования природных и антропогенно-преобразованных экосистем [Электронный ресурс] : материалы V Международной научной конференции, посвященной 90-летию кафедры почвоведения и оценки земельных ресурсов ИГУ, Иркутск, 23–29 августа 2021 года С. 257-260Abstract: The effectiveness of vermidumate, which was obtained by extracting humic acids from vermicompost 0.02 n NaOH, is shown. Vermicompost was obtained by processing food waste by the California worm Eisenia Andrei Bouche. Its richness with organic matter (46 %), gross and mobile forms of nitrogen (2.13 % and 345 mg/100 g, respectively) and phosphorus (0.63 % and 500 mg/100 g), high alkalinity (pH = 9.18) are shown. The content of humic acids is more than 2 times higher than the proportion of fulvic acids, the type of humus is humate, calcium humates dominate in the composition of humic acids. Radish was selected as a test crop. The effect of vermigumate irrigation in the field experiment on agro-gray soil was studied. Vermigumates contributed to an increase in seed germination energy by 33 %. The increase in the productivity of the test culture against the background of irrigation with the vermigumate (dilution 1:50) was 42 % compared to the control.
