Subtopic: Leaching requirement and salinity control
Question Statement:
Identify the adverse effect(s) due to soil salinity or alkalinity or both:
Options:
(A) Low yields of crops
(B) Increased infiltration leading to waterlogging
(C) Poor quality of fodder
(D) Limited type of crops can be grown
Official Answer Key:
A, C, D
Step-by-Step Solution & Explanation
Salinity/sodicity reduce crop yield, degrade fodder quality, and restrict crops to only salt-tolerant species. Option (B) is incorrect because sodic/alkaline soils cause clay dispersion, which reduces (not increases) infiltration — the resulting waterlogging is due to poor drainage from reduced infiltration/permeability, not increased infiltration.
