Show answer and explanation

Correct answer: (A) Low crop yields; (C) Poor fodder quality; (D) Restricted choice of crops

Explanation

Salinity imposes osmotic and ionic stress, and sodicity can impair soil structure; these reduce crop yield, limit suitable species and impair fodder quality. Sodicity generally reduces infiltration through dispersion rather than increasing it. Hence **A, C, D** are correct and B gives the wrong infiltration mechanism.
