All about Soil
Soil is the thin layer of material on the surface of the land where plants grow. It is made from broken-down rock, decayed plants and animals, water and air. Healthy soil holds water and provides nutrients that plants need to grow.
Worms, insects, fungi and bacteria live in soil and help break down materials and keep it healthy. Soil takes many years to form, so protecting it from erosion and pollution is important for farming and nature.
