Soil Salinization

The geochemistry of soil salinization refers to the study of the chemical processes and interactions that lead to the accumulation of soluble salts in soil, often resulting from factors such as evaporation, irrigation practices, and the mineral composition of the parent material. This phenomenon affects soil fertility and can have significant implications for agricultural productivity and ecosystem health.

Key Terms

Salinity
The concentration of salts in soil or water.

Example: High salinity can lead to poor plant growth.

Evaporation
The process by which water turns into vapor and leaves the soil.

Example: Evaporation increases salinity in arid regions.

Irrigation
The artificial application of water to soil for agriculture.

Example: Improper irrigation can cause salinization.

Soil Amendments
Materials added to soil to improve its physical or chemical properties.

Example: Gypsum is a common soil amendment to reduce salinity.

Drainage
The removal of excess water from soil.

Example: Good drainage helps prevent salinization.

Toxicity
The degree to which a substance can harm organisms.

Example: High salt levels can be toxic to plants.
