Topsoil

Topsoil is the uppermost layer of soil, typically rich in organic matter and nutrients, making it essential for plant growth. It usually extends about 2 to 8 inches deep and is where most of a plant's roots are found. This layer is crucial for agriculture and gardening because it supports a wide range of biological activity, including worms, microorganisms, and fungi, all of which contribute to soil health. Maintaining topsoil quality is vital for environmental sustainability, as it helps retain water, reduce erosion, and foster biodiversity.
