Effect of soil salinity and sodicity was investigated on the infiltration capacity of four soil types; normal, saline, sodic and saline-sodic. Bulk density, porosity, moisture holding capacity, and texture of soil samples were also determined in the laboratory. The results showed that the infiltration capacity was highest in normal soil (0.17cm/hr). The infiltration capacity of saline-sodic soil under different vegetation e.g. tree plantations, grass cover and bare soil differed significantly although other physical characteristics were not significantly different.
