Under organic fertilization systems on gray forest soil in the buckwheat-barley-oats crop rotation link, a deficit-free nitrogen balance was determined for the application of 12 t of cattle manure per 1 ha of crop rotation area (60 t/ha for 5 years), which was (+22 kg/ha) and for the use of organo-mineral bioactive fertilizers of the Organic brand at a dose of 2 t/ha – (+36 kg/ha). When applying a half dose of cattle manure – 6 t/ha and OMBD – organic – 1 t/ha and stubble biodestructor, a negative nitrogen balance was established with the corresponding values ​​of (-11) kg/ha, (-9), and (-20) kg/ha. Positive indicators of the balance for phosphorus and potassium were determined for all variants of organic fertilization systems in the crop rotation link for phosphorus (+9)–(+46) kg/ha and potassium – (+38)–(+105) kg/ha. The economic and energy efficiency of organic fertilization systems of short-rotation crop rotation was determined. The prospects of using OMBD - organic, in doses of 1 and 2 t/ha, were established, with the following indicators of the level of profitability for oats - 221 and 227%, barley - 100 and 105%, and buckwheat 149 and 148%, as well as an increase in energy efficiency coefficients, respectively, to 4.4–5.5, 4.2–4.0 and 2.7–2.2. It was established that compared with the application of organic fertilizers - cattle manure in doses of 6 and 12 t/ha of crop rotation area, the use of OMBD brand organic in doses of 1 and 2 t/ha increases the level of profitability of agricultural crops by 34–51% and the energy e Product Description popup.authors popup.nrat_date 2025-07-02 Close
