Notes: Alluvial soil consists of a mixture of various soil particles, including silt, sand, clay, gravel as well as organic matter. Gravel is not as common as the other three components. The main constituents of alluvial soil are silt, sand, and clay, which are typically carried and deposited by water, such as rivers and streams. This type of soil is often fertile and well-suited for agriculture due to its mineral-rich composition and good drainage properties.
