Land pollution in which land is unsuitable for farming due to high salt contentis known asans.

The type of land pollution where land becomes unsuitable for farming due to high salt content is known as Salinization.

Here are the steps that explain this process:

1. Salinization often occurs in areas where irrigation is used to grow crops.

2. When water is applied to the fields, it evaporates, leaving behind salts and minerals that were dissolved in it.

3. Over time, these salts accumulate in the soil, increasing its salinity.

4. High salinity levels can harm plants by affecting their ability to absorb water and nutrients.

5. As a result, the land becomes less productive and may eventually become unsuitable for farming.

6. This process of increasing soil salinity and the resulting decline in soil fertility is known as salinization.
