. The primary method of controlling soil salinity is to permit 10-20% of the irrigation water to leach the soil, that will be drained and discharged through an appropriate drainage system. The regular surface drainage systems, which start functioning as soon as there is an excess of rainfall or irrigation applied, operate entirely by gravity. Irrigation and drainage; principles and practice of their cultural phases [King, Franklin Hiram] on Amazon.com. Irrigation and drainage can improve or degrade ecosystems and the environment.
