Aquatic soil refers to the soil found in or near water bodies, such as rivers, lakes, and wetlands. This type of soil is often saturated with water, which affects its physical and chemical properties. Aquatic soils play a crucial role in supporting aquatic ecosystems by providing nutrients and habitat for various organisms. These soils are typically rich in organic matter due to the decomposition of plant material and other organic substances. They also help filter water, improve water quality, and store carbon, making them important for environmental health. Understanding aquatic soil is essential for managing wetlands and preserving biodiversity.
