Planting Your Vegetables and Cash Crop Seeds in Soil: Simple Steps for Successful Cultivation.

The earth's crust consists of three layers, namely, a surface layer of topsoil, a middle region of subsoil and solid rock  in the interior. Topsoil is the surface soil. It consists of soil particles of varying sizes. It is only a few centimetres deep and is occupied by plant roots and other living organisms. This layer is dark in colour because it contains humus; the brown organic substance formed by the decay of plant and animal matter. Topsoil also contains many chemical substances which plants need.

Below this band of topsoil is a wider zone of subsoil which is often of a lighter colour than the topsoil. Subsoil is composed mostly of large soil particles and stones. Sometimes, plant roots penetrate into the subsoil. The rocky base of the subsoil is the parent material that gradually weather's, or breaks down, to produce more soil above it. Land that has holes are fertile, because of earth worms.
