HARMFUL SALTS IN SOILS

  • If the amount of harmful salts becomes excessive in the soil no crop can be grown over it.
  • Sodium carbonate, sodium chloride, sodium sulfate, etc. are some of the harmful salts.
  • But of these, sodium carbonate which is also known as white salt is considered to be the most harmful.
  • If the percentage of harmful salts reaches 0.15 percent it affects the production and if this percentage reaches 0.25 percent it renders the land completely barren.
  • Other salts are also present in the soil but unless their percentage crosses the limit they do not affect the growth of the crops.

The pH value of the soil suitable for crops should lie between 6.0 and 8.5. If pH value exceeds 10.5 the land becomes completely unsuitable for crops.
