Investigating the Suitability of Drainage Channels Water for Irrigation in Bafra Plain

Öz

In this study, drainage effluent water quality parameters of Muamlı and Bedeş drainage canals, to which there are not any intrusion from other places, were monitored year-long and the effects of drainage canals on salt leaching from plain soils were assessed. Water samples were taken from 9 different locations of Muamlı and Bedeş canals in July and September. Soil samples were taken from paddy fields irrigated with the effluents of these drainage canals after the harvest. Water and soil samples were analyzed for different quality parameters. Present findings revealed that water samples did not have any problems with regard to residual sodium carbonate (RSC), sodium, sulphate and chlorine and can be used safely. For Salinity of water samples taken from Muamlı drainage canal (EC_w)varied between 2.79-2.97 dS/m and EC_w values of Bedeş drainage canal varied between 1.01-4.95 dS/m. It was concluded that drainage canal effluents created serious salinity problems and ultimately resulted in significant yield losses
