Abstract :This study was conducted to determine the salinity and alkalinity levels of irrigation water resources and agricultural lands in Konya-Karatay-Çengilti Town. On the map of research, samples points were selected at certain places on the main drainage canal of Konya. In these places, disturbed soil samples were taken from 0-30 cm, 30-60 cm and 60-90 cm by use of auger. Undisturbed soil samples were taken through the 1.5m soil depth from 1,5 m distance from both sides of canal. Water samples used for irrigation of selected agricultural lands were taken from twice (summer and fall seasons) from groundwater resources and main drainage canal. Soil and water samples were analyzed in laboratory. The results showed that research soils are clay textured with %45,91-71,74 lime content. Field Capacity (FC) and Wilting Point (WP) and pH values were %24,8-37,4, %13,6-23,2 and 7,17-8,60 respectively. EC, Cation Exchange Capacity (CEP), organic matter, boron content and Exchangeable Sodium Percentage (ESP) were determined as 1137-13314 µmhos/cm, 9,37-15,84 me/100g, %0,27-2,47, 0-9,1 ppm and %1,64-48,58 respectively. In examine the water samples of summer season, pH and electrical conductivity were 7,02-8,30 and 1620-9741 µmhos/cm, respectively. In some samples, residual bicarbonate, RSC was determined. Boron content was 0,1-2 ppm. The %41,7 of water samples were classified as T3S1; %4,2 of T3S2, %20,8 of T4S1 and %33,3 of T4S2 irrigation water. In examine the water samples of fall season, pH and electrical conductivity were 6,91-7,76 and 1610-9157 µmhos/cm, respectively. None RSC was de-termined in all water samples. Boron content was 0,3-1,9 ppm. The %47,4 of water samples were classified as T3S1; %26,3 of T4S1 and %26,3 of T4S2 irrigation water. The 47.4%, 26.3%, and 26.3% of total samples were T3S1, T4S1 and T4S2 irrigation water class, respectively, and these aren’t suitable for irrigation according to the salinity. In examine the alkaliny hazards; they could be used in irrigation with good care.Keywords : Tuzlu-sodyumlu toprak, sulama suyu kalitesi, drenaj suyu
