Which outcome occurs when excessive irrigation accelerates weathering?

A)Salt accumulation in upper soil
B)Increased soil organic matter
C)Enhanced aggregate soil stability
D)Reduced soil erosion rates

💡 Explanation

Irrigation causes mobilization of salts through leaching. Capillary action then concentrates these salts at upper levels because water evaporates, therefore causing salinization, rather than improving soil structure or fertility, because erosion rates will tend to remain level or in fact rise.
