- Sand is the largest particle found in soil. When you rub it, it feels rough and gritty. Sand does not have many nutrients, but it dries quickly after rainfall, and it is good for drainage, which means it lets water flow through it easily.
- Silt is the medium-sized particle found in soil. Silt feels smooth and powdery when dry, and it feels slippery when wet. Silt can be packed down into a crust that makes it harder for water and air to pass through it.
- Clay is the smallest particle found in soil. Clay feels smooth and hard as stone when dry, and it feels sticky when wet. While clay can hold many nutrients, it does not allow much air or water to pass through. Too much clay can make the soil too heavy and not good for growing plants.
- Loam is a mix of sand, silt and clay. It is the best type of soil for growing plants. Loam learns out easily and holds moisture and nutrients, while still allowing some air and water to pass through.
