Field and laboratory experiments were conducted to study the effect of physical properties on water entry in three soils, differing appreciably in texture. The results indicate that the saturated hydraulic conductivity (K) of lateritic soil was manifold higher than the alluvial soil. In lateritic soil the value of K was 10 −1 cm/hr and it ranged from 10 −2 to 10 −3 cm/hr in alluvial soil. In general, the conductivity decreases in the sub surface layers and may be attributed high bulk density resulting from compact blocky structure of the soil. The infiltration rate of lateritic soil was found to be 4 times more as compared to the alluvial soils.
