Irrigation of a saline-sodic site in the Sudan Gezira. II- Salt movement and sodicity changes
and
In a saline-sodic site in northeaster Gezira, irrigation with Blue Nile water and cropping with alfalfa caused a net downward movement of salts. Forty months of watering reduced the exchangeable sodium percentage from above 50 to below 10 in the top 30 cm. The ultimate characteristics of the profile will depend on the management and the rate at which these processes take place.
