← GeographyWhich increased consequence occurs when intensive irrigation mobilizes salts?
A)Enhanced soil structural instability (slaking)✓
B)Reduced silicate mineral formation rates
C)Decreased infiltration capacity temporarily
D)Accelerated biochemical nitrogen fixation rates
💡 Explanation
Mobilized salts cause increased *osmotic potential*, resulting in 'slaking': soil aggregates disaggregate upon wetting due to internal stresses. Because of osmotic potential, soil instability increases, rather than enhanced biochemical activity or quicker temporary soil infiltration.
