describe how soil damage due to salinity could be reduced?
proper irrigation management
salinity is an important land degradation problem. soil salinity can be reduced by leaching soluble salts out of soil with excess irrigation water. soil salinity control involves watertable control and flushing in combination with tile drainage or another form of subsurface drainage. a comprehensive treatment of soil salinity is available from the united nations food and agriculture organization.

soil salinity
salinity displays a positive correlation with magnesium:calcium (mg:ca) ratios, though shows only about half as much influence as temperature. salinity in some systems can account for about 25% of the variation in mg:ca ratios, with 32% explained by temperature, but these salinity induced changes in shell mgco incorporation are not due to differences in available magnesium. instead, in planktonic foraminiferans, changes in salinity could hinder the internal mechanisms of magnesium removal prior to calcification. foraminiferans are thought to produce calcification vacuoles that transport pockets of seawater to the calcification site and alter the makeup of the seawater and remove magnesium, a process that may be interrupted by high levels of salinity. salinity can also affect the solubility of caco, as shown by the following formulas relating temperature (t) and salinity (s) to k’, the apparent solubility product constant for caco.
