Opportunities for alternate land uses in salty and water scarcity areas

J C Dagar

Abstract


Vast tracts of arid and semi-arid areas of the world are salt-affected (nearly 1 billion ha) and remain barren due to salinity or water scarcity.  The salt-affected lands (sodic/alkaline and saline) constrain plant growth owing to the osmotic effects of salt, poor physical conditions leading to poor aeration, nutrition imbalances and toxicities.
