Sodic Soils

• stick to plant root systems ➡️ reducing osmotic capability
  • wilting of roots

What can be done?

• introducing ➡️ Gypsum (CaSO₄)
  • ⬇️ con^c of NaCl
    • dissolution of NaCl in water (through chemical rxn)
    • clearing the passage of water from soil
    • remaining CaSO₄ ➡️ also to be cleared
      • as it is also a salt.

⁘ refer: Alternative to Gypsum

NaCl

• dominant salt
  • deposited over the field
  • found in highly saline soils
• less solubility in water
