The presented article is devoted to the study of the reclamation state of the lands of the selected experimental research site under tomatoes with various methods of irrigation (drip-furrowed) on the territory of a farm in the Shabran region of Azerbaijan. The yield of agricultural crops on slightly saline soils decreases by 20%, in moderately saline soils - by 50%, in highly saline soils - by 70%, and in very highly saline soils - by 90%. Soil fertility and all valuable agronomic features depend on the amount of humus in the arable layer.
