Question

Quizplus · Accepted Answer

When water is applied to soil through irrigation, it dissolves salts that are naturally present in the soil. As the water evaporates, the dissolved salts are left behind on the soil surface, where they accumulate and can become concentrated enough to be harmful to plant growth. This process is known as salinization.
