Alkaline soils

Alkaline soils, also known as sodic soils, belong to the category of problem soils. This is because they have a basic limiting factor for plant growth, a factor which, depending on its level, makes it correspondingly prohibitive to use these soils for the cultivation of any plant. This factor is the alternative Na+, which due to its high concentration degrades the chemical and physical characteristics of the soil and has a toxic effect on plant growth, making the soil an unsuitable environment for crop growth.
