2 CHARACTERISTICS OF GYPSIFEROUS SOILS

When gypsiferous soils are irrigated, the gypsum is leached and translocated and in some cases a gypsum layer is formed which reduces the hydraulic conductivity Keren et al (1980) suggest that the reduction in the hydraulic conductivity is due to the plugging of soil pores by the precipitation of the leached gypsum
