The effectiveness of using organic fertilizers produced by methods of biological fermentation and cavitation in the technology of growing wheat in the conditions of western forest-steppe has not been studied sufficiently. The results of our research prove that the introduction of organic fertilizers Biofirms in a dose of 10 t/ha and Biohrom liquid organic fertilizer in a dose of 5 liters per hectare provide an increase in conditionally net income, profitability, cost reduction and the production of environmentally safe grains of spring wheat from content of the required amount of trivalent chromium. It was established that the introduction of a 10 ton/hectare organic fertilizer "Bioproferm" with a balanced content of tri-chromium and spraying of spring wheat plants during vegetation with liquid organic fertilizer Biohrom in a dose of 5 liters per hectare conditionally net income was 9,245 UAH/ha or by 5650 UAH/ha more, compared to control, by 5140 UAH/ha more than the variant where they brought N120P80K80 and 1547 UAH/ha more to the variant where organic biofertilizers were introduced in a dose of 10 t/ha and sprayed plants of spring wheat during vegetation of liquids of organic fertilizer "Biohrom" a dose of 5 l/ha. The profitability level was 68.1 % or 39.6 % higher, compared to control. The introduction of organic fertilizer "Bioproperments" at a dose of 10 t/ha and Biohrom liquid organic fertilizer in a dose of 5 liters per hectare provided a reduction of the cost of spring wheat grain by 646 UAH/t compared to the control.
