Role of Continuous Irrigation in the Improvement of Saline Sodic Conditions of the Desert Soils

Abstract

Comparison of the saline-sodic conditions developed in a desert soil under continuous irrigations with saline waters h with fallow-c as been made u m -irrigated and continuous fallow soils. It has been observed that the levels of salt and sodium in top layers of the continuously irrigated soils is less as compared to others. Continuous irrigation onpermeable, well drained soils helps in checking the excessive development of salt in the surface layers because the salts accumulated during the previous irrigation are leached clovvn to deeper layers due to the precipitation of about 50 crns. in the intervening period, followed by supplemental irrigation in the ensuing season.
