Effects of Soil Salinity and Alkalinity

 

1. In alkali condition, soil is dispersed and becomes compact.
2. Less water permeability due to compactness.
3. Low aeration.
4. Low microbial activities.
5. Unavailability of nutrients like P, Ca, N.
6. Nutritional disturbances at pH 8.5 and more.
7. Hindrance in water absorption.
8. Increase in osmotic pressure of soil solution badly affects the plants growth.
9. In alkali soil highly toxic Na2CO3 is present.
