to prevent seepage of water.

The quality of the irrigation water in relation to the alkalinity hazard is expressed by the following two indexes:

1. The sodium adsorption ratio (SAR, )

The formula for calculating sodium adsorption ratio is:

:where: [ ] stands for concentration in milliequivalents/liter (briefly meq/L), and { } stands for concentration in mg/L.

It is seen that
