Аннотация

In the article, the application of Baikal EM-1 microbiological fertilizer N₁₅₀ P₁₀₅K₇₅ and N₂₀₀ P₁₄₀K₁₀₀ kg/ha in the conditions of old irrigated typical gray soils improved soil agrochemical properties and plant nutrient absorption. "Baikal EM-1" microbiological fertilizer is in the form of an aqueous solution, the microorganisms in it enrich the soil with various enzymes, physiologically active substances, etc., enhance the activity of mineral fertilizers, and increase soil fertility by absorbing nitrogen from the air. In the conducted research and experiments, it was determined that when Baikal-EM-1 microbiological fertilizer is added to the soil in an acceptable amount, the physiological process, photosynthesis and respiration of plants are improved.
