When does soil salinization occur?

When you use irrigation water, you should be extremely careful about the quantity and timing of the application because salty soils are typically found in arid and semiarid climate regions, where annual precipitation is insufficient to meet plant needs. As a result, salts are not leached from the soil when irrigation is done, and they accumulate in detrimental amounts to plant well-being when water evaporates quickly but salt in the water remains.

Soil salinization occurs when the concentration of soluble salts in the soil increases to levels that are harmful to plant growth. This typically happens in arid and semi-arid regions with low rainfall and high rates of evaporation, where salts accumulate in the soil over time. Additionally, soil salinization can occur due to human activities such as irrigation with saline water, excessive fertilizer application, and poor drainage practices.
