Abstract. This article focuses on the technological optimization of the structure of alluvial-meadow-forest soils in the north-eastern region of Azerbaijan. Under the conditions of the transition to intelligent agriculture (Smart Farming), the water resistance of soil aggregates is considered a key indicator of agroecosystem stability. Experimental results demonstrated that the application of biotechnological vermicompost at a rate of 7 t ha⁻¹ provided the highest content of water-resistant aggregates (>0.25 mm), reaching 71.6%, which significantly exceeded the values obtained under conventional mineral fertilizer systems. Comparative analysis confirmed the technological superiority of organic fertilization in promoting stable soil aggregation and reducing the risk of irrigation-induced soil erosion.
