Which outcome occurs when excessive irrigation precedes leaching?

💡 Explanation

Increased irrigation elevates water tables, mobilizing salts. Capillary action brings these salts to the surface via evaporative concentration, leading to **salinization**, because saline water is drawn upwards rather than downwards. Therefore, salinization increases, rather than reduced weathering.
