Abstract

Combined leaching-infiltration tests showed no structural deterioration of saline-alkali soils even after percolation of large amounts of water through the profile. Exchangeable-Na percentage decreased to 2-4 according to irrigation-water quality and drainage conditions, simultaneously with the total salt content, but at a slower rate. Graphs showing the relationships between pH, exchangeable-Na percentage and electrical conductivity (pH decreasing with increasing salt content, exchangeable Na increasing with increasing salinity at constant pH) may be used for the determination of alkalinity level from measurements of pH and salinity. Results indicate that there is no danger of these saline-alkali soils of high lime status (25-27 %) developing into alkali soils by reduction of the salinity through leaching.
