Present study was undertaken at Hirakud command area of Odisha to investigate the effect of continuous irrigation on soil texture, bulk density and saturated hydraulic conductivity of different soils. Soil samples were collected from 15 spots each at irrigated areas and unirrigated areas in two different depths at 0-15 cm and 15-30 cm with Global Positioning System (GPS). Both loose and core samples from each spots were collected and analysed for different physical properties. The textural classes for surface soil of both the areas varied from sandy loam to sandy whereas for sub surface soil the textural classes of both irrigated as well as unirrigated areas varied from sandy clay loam to sandy and sandy loam to sandy clay loam respectively. Sand content was more in irrigated areas () than unirrigated areas (83%) due to continuous irrigation. The range of bulk density for unirrigated areas varied highest from Mg/m3 than irrigated areas. The value of saturated hydraulic conductivity for surface soil was higher than sub surface soil of both irrigated and unirrigated areas. The sand content of surface soil of both areas was positively correlated with bulk density and saturated hydraulic conductivity. | Effect of continuous irrigation on soil texture, bulk density and saturated hydraulic conductivity of some soils in Hirakud command area of Odisha, India
