Hydraulic properties of soils play a significant role in development and adoption of suitable water management practices capable of increasing input use efficiency of soils for maintaining agricultural production of arid and semi arid regions. The study was carried out to investigate the hydraulic properties of soils varying in texture, organic carbon and salt contents. The soil samples were collected from 0-15 and 15-30 cm depths at farmers’ field in different villages spread over nine districts of the Haryana state during 2016-17. The experimental soils were found to belong to six textural classes ., sand, loamy sand, sandy loam, loam, silty loam and sandy clay loam having silt + clay content from 6- 40 %. The organic carbon (OC) content, electrical conductivity, pH, saturated hydraulic conductivity (Ksat), sodium adsorption ratio, moisture at field capacity and permanent wilting point soils were determined using standard methods. The Ksat of the soils was found of to be significantly and exponentially positively correlated with bulk density (R2 = ) and negatively correlated with silt+clay content (R2 = ) at 0-15 and 15-30 cm depths. The Ksat had significant and exponential negative correlation with soil OC at 0-15 cm (R2 = ) and 15-30 cm (R2 =) in the present study. | Investigation of hydraulic properties of soils varying in texture, organic carbon and soluble salt contents of arid and semi-arid regions
