Eco-meliorative monitoring and evaluation of the state of irrigated lands in the influence zone of the system of Samur-Absheron channel in connection with its reconstruction

Resumo

Monitoring sites were selected on characteristic areas in the influence zone of the system of Samur-Absheron channel (SAC) in connection with its reconstruction. According to the results of monitoring, eco-meliorative state of irrigated lands of these sites was evaluated. Recommendations were given for the improvement of meliorative state of irrigated lands of the areas under consideration. Samur-Absheron channel, which provides the cities of Baku and Sumgait, Absheron peninsula, and parts of the northern zone of the Republic, has been operated for more than 50 years uninterruptedly and without reparation. After the reconstruction of the system, the discharge of the channel will increase from 55 to 83.1 m³/s, and the irrigated area will increase from 149300 to 183500 hectares, in which connection eco-meliorative state of lands of the adjacent areas will change. As a result of monitoring carried out, it was determined that the waters are quite suitable for crop irrigation, do not cause soil salinity, and do not impair biological processes in plant development.
