Abstract

Water-physical properties of the soil are not constant, they often are changed under the influence of natural conditions and agrotechnical measures. Studies show that water-physical properties directly affect the life and growth of plants. In this regard, the main tasks are to study the changes in water and physical properties of the soil under various crops in irrigated areas and to develop the systems of agromeliorative measures. As a result of researches the water-physical properties of irrigated meadow-gray soils of the experimental site at the Salyan plain were studied: physical clay – 48.2...56.79%, density of solid phase – 2.62...2.73 g/cm³, density of dry soil – 1.22...1.46 g/cm³, total moisture capacity – 31.86...43.80%, soil porosity – 46.52...53.44 %, CaCO₃ – 11.11...14.96%, pH – 8.2...8.6, SO₄ in gypsum – 0.077...0.899%, the ratio of absorbed bases – 12.27...15.96 milligram equivalents. Researched soils have a weak and medium degree of water permeability (K_t = 5.51...8.83 cm/h the Kostyakov equation). The traditional and modern methods of irrigation (furrowing, sprinkling, drip, etc.), application of fertilizers (organic, mineral and micro fertilizers, local fertilizers, silt deposits of river waters, etc.) are recommend as agrotechnical measures in accordance with preliminary study of ratio of salts in soil.
