4. Introduction
These soils are both saline and alkali.
There can be all stages in transition with varying degree of dominance of salt content
and pH
According to movement of soluble salts, formation of saline-alkali and non-saline alkali
soils depends.
Soil contains Na-clay as well as excess soluble salts.
