The excessive use of water for crops, non-cemented canals and a poor drainage system are causing waterlogging and salinity in the area. ... This ultimately results in waterlogging. “The stagnant water gradually turns saline and destroys nearby arable lands.”

Why does waterlogging increase salinity?

In irrigated agricultural land, waterlogging is often accompanied by soil salinity as waterlogged soils prevent leaching of the salts imported by the irrigation water. ... The higher salinity and higher levels of specific ions often reflect the characteristics of the soil through which the irrigation water has percolated.

Is water logging and salinity?

The combined salinity and waterlogging have more harmful effects on crop growth and yield than the individual effect. Waterlogging causes plants to become shallow-rooted, which results in salinization as salts move up because of capillary action that eventually makes the land inappropriate for agriculture.
