Irrigation Water Quality Assessment for Water Resources Used in Irrigation of Agricultural Fields of Kütahya - Alayunt Village

Abstract— This study was conducted to assess the irrigation water quality of deep wells in Kütahya- Alayunt village and to assess the salinity-alkalinity of agricultural fields irrigated with these waters. The pH values of water samples taken in May, June, July, August and September varied between 7,12 - 8,57 and electrical conductivity (EC) values varied between 563 - 1483 µmhos/cm. According to US Salinity Lab. Classification System, water samples were classified as C2S1 (moderately saline – low alkaline) and C3S1 (highly saline – low alkaline). Differences were observed in irrigation water quality criteria throughout the irrigation season. Soils of the research site had loamy (L) and clay-loam (CL) textures. Soil pH values varied between 7,23 - 7,94 and EC values varied between 485 - 1652 µmhos/cm
