Which outcome occurs when irrigation in arid climates mobilizes soluble salts?

💡 Explanation

Surface accumulation happens because capillary action coupled with the **leaching** of alkaline minerals draws dissolved salts upwards; therefore, soil salinization concentrates near the topsoil layer, rather than nutrients necessarily becoming chelated or horizons rapidly differentiating.
