Despite its stark and devastating appearance, all salt induced problems can be corrected by the engineering solution of sub-surface drainage.

Technically it is simply a process of installing a drainage system deep in to the soil profile, and then using natural rainfall or quality irrigation water to flush the salts from the profile. The economics however, can have a greater bearing on the outcome. Factors that need to be considered before embarking on a desalinisation project are crop value, land value, access to flushing water, and if safe disposal of saline discharge can be achieved.

In many instances, especially in horticultural enterprises, sub-surface drainage is best considered as an insurance policy, if there is the slightest chance of soil salts affecting sensitive crops.
