What is saline-alkali land?

This word refers to land with excessive salinity.

Saline-alkali land, also known as saline-alkali land or alkaline land, refers to land with saline-alkali content exceeding a certain standard. Excessive accumulation of saline-alkali components in this kind of land is harmful to the growth of crops.

Saline-alkali land is a kind of low-yield land, because it can increase the concentration of soil solution, resulting in crops unable to absorb the required water. At the same time, the content of soil organic matter and nutrients is low, and the soil structure and physical properties are poor.
