The type of soil with a particle size of 0.02 to 0.002 mm is called "silt". Silt is a fine-grained soil that is composed of rock, mineral, and organic particles that are smaller than sand but larger than clay. It has a smooth, silky texture and can retain moisture better than sand due to its smaller particle size. Silt is often found in river beds, floodplains, and areas where there has been erosion and deposition of sediment. Its ability to retain moisture and nutrients makes it suitable for agriculture, as it provides a good growing medium for crops.
