Sodic soils are a type of soil that contains a high percentage of sodium ions, which can negatively affect soil structure and fertility. These soils often have poor drainage and can become compacted, making it difficult for plants to grow. The high sodium levels can also lead to the dispersion of soil particles, further reducing soil quality. Management of sodic soils typically involves the application of amendments, such as gypsum, to help replace sodium with calcium. This process improves soil structure and enhances water infiltration, promoting better conditions for plant growth. Understanding and managing sodic soils is essential for sustainable agriculture and land use.
