Chapter 11: Problem 14

What is meant by salinization, and what are its consequences? How does salinization result from irrigation?

Short Answer

Expert verified

Salinization is the buildup of salts in soil, typically in arid regions. It has several negative impacts, particularly on agriculture, as it can inhibit crop growth and degrade soil structure. Salinization can result from irrigation as irrigation water often contains dissolved salts, which remain in the soil after the water evaporates or is taken up by plants.

Step by step solution

Definition of Salinization

Salinization is the process by which water-soluble salts accumulate in soil. This condition often arises in semi-arid regions where water evaporates quickly, leaving behind its salt content.

Consequences of Salinization

Salinization has several effects, especially in agricultural lands. It can inhibit crop growth or even kill crops due to the high salt content in the soil. These salts can also degrade the soil structure, reducing its ability to retain water and leading to increased soil erosion.

Salinization Resulting from Irrigation

Irrigation can lead to salinization when the irrigation water, containing dissolved salts, is applied to lands over a long period. When the water evaporates or is taken up by plants, the salts remain in the soil. Over time, salts can accumulate to toxic levels, leading to the salinization condition.
