Choose the correct statement :

सही कथन का चयन कीजिए :

The clay of saline soils is often deflocculated. लवणीय मृदाओं की क्ले अक्सर वि-ऊर्णित होती है। The reclamation of sodic soils is easier than saline soils. सोडिक मृदाओं का सुधार लवणीय मृदाओं की तुलना में अधिक आसान है। Coarse textured soils are generally more affected by exchangeable sodium than fine textured soils. मोटी गठन वाली मृदाएं बारीक गठन वाली मृदाओं की तुलना में विनिमयशील सोडियम से अधिक प्रभावित होती हैं। The degree of swelling is related to the specific surface of soils. मृदा के फूलने की मात्रा मृदा की विशिष्ट सतह से संबंधित है।
