Silt. Silt may occur as a soil (often mixed with sand or clay) or as sediment mixed in suspension with water (also known as a suspended load) and soil in a body of water such as a river.
Also asked, what is good about silt?
Such deposits of silt are known as loess. Silty soil is usually more fertile than other types of soil, meaning it is good for growing crops. Silt promotes water retention and air circulation. Too much clay can make soil too stiff for plants to thrive.
Why is it important to have air in the soil?
(1) Animals that live in the soil (like worms) and many types of bacteria that are important for other plants and animals need air to breathe. (2) Plants need air to breathe too - really! One of the ways that plants get air is by absorbing it through their roots.
What is the difference between sand and silt?
Clay has super fine particles that cling together and prohibit water and nutrient movement, while sand has course particles which allow water and nutrients to leach too rapidly. There actually is one more classification called silt which has particles sized between clay and sand.
