In intensely irrigated farmland, which consequence commonly follows disruption of the capillary fringe?

💡 Explanation

Increased soil salinization arises from disrupting the capillary fringe, because upward water movement due to capillary action pulls dissolved salts to the surface; therefore, water evaporation leaves accumulated salts, driving salinization, rather than other pedogenic processes or hydrogeological effects.
