Management Aspect for Crop Production

Loss of crop productivity from excess soil salinity is a worldwide problem. In arid and semi-arid regions salinity is a continual threat; but even in humid areas salinity is a hazard when irrigating with brackish water or treated sewage effluent, or because of seawater intrusion. Although soil salinity can sometimes be moderated by applying appropriate water management practices, adverse levels of soil salinity are often difficult to prevent because of a lack of nonsaline irrigation water or because of other physical constraints.
