The main factors influencing soil moisture retention capability were studied by the methods of correlation and path analyses. The results indicated that < 0.02mm physical clay and soil salt content were the main factors influencing soil moisture retention capability. At soil suction of 30-50 kpa, the soil salt content would be the dominant factor.展开更多

During the study, changes in the physical properties of water, land drainage, groundwater level, mineralization, soil salinity of this territory have been investigated as well. Studies show that in the current territory elevated levels of ground water in drainage and irrigation networks, revealed that their mineralization and the amount of salts in the soil were under bad condition. On the basis on studies measurements for soils state in Mugan-Salyan massif have been presented.展开更多
