← GeographyWhich outcome occurs when agricultural soil experiences excessive water infiltration?
A)Nutrient depletion via eluviation process✓
B)Increased cation exchange capacity (CEC)
C)Enhanced soil aggregation stability
D)Decreased risk of waterlogging events
💡 Explanation
Nutrient depletion occurs through eluviation (a type of leaching) because water carries dissolved minerals downwards, therefore the upper soil loses fertility rather than gains cation capacity; the transport destabilizes aggregated soil; it also increases the potential for waterlogging if drainage is poor.
