Salt is a contaminant for soils because many plants doesn't accept too much salt in soil.
when plants are grazed too much too often , the roots deplete and die off . plants also tend to be grazed close , which makes the soil lose its quality and productivity.

When there is an increase in hydrogen ion concentration, the soil becomes acidic. Too much acidity in the soil can kill plants.

too much salt in the water inhibits the plants ability to draw water from the soil and eventually it will die of thirst
The percolation ability of soil is important to sustaining plant life because it affects how much water is retained in the soil. If too much or too little water is in it, the plants may not have the amount it needs.
salt content in the soil that reduce fertility
