Saline-alkaline soil is a type of soil characterized by high levels of soluble salts and a high pH, which makes it alkaline. This soil type often contains sodium, calcium, and magnesium salts, which can negatively affect plant growth by limiting nutrient availability and water absorption. It is commonly found in arid and semi-arid regions where evaporation exceeds precipitation. The presence of saline-alkaline soil can lead to challenges in agriculture, as many crops struggle to thrive in such conditions. Management practices, such as improving drainage and applying organic matter, can help mitigate the adverse effects of this soil type and promote healthier plant growth.
