The article shows the possibility of food waste recycling using vermiculture method into an effective environmentally friendly fertilizer named biohumus (vermicompost). The purpose of the research was to study the effect of new type of biohumus and azophoska on grey forest soil fertility indicators and corn yield. Testing of fertilizers was performed during the growing-field experiment. It was found that the insertion of different doses of fertilizer into grey forest soil causes significant increase in humus content compared to reference. The exception was the variant with azophoska inserted at a dose equivalent to 3 t/hectare of vermicompost, where its content was at the reference level. The insertion of 3 and 6 t/hectare of biohumus caused soil environment reaction change from weakly acid (reference) to close to neutral. The insertion of 3 t/hectare of vermicompost into the soil along with azophoska inserted in amount the same as biohumus promoted statistically significant increase in gross forms of nitrogen, phosphorus as well as formation of the maximum yield of corn, which increase was 24 % compared with the reference level. It is shown that the energy efficiency of vermicompost is higher than that of azophoska and varies from 2,28 to 8,78 units depending on the experiment variant.
