Learn what a soil profile is, how it is formed, and why it is important for agriculture and environmental science. A soil profile is a vertical section of the soil that shows its horizons, from the surface to the rock, and reveals its history and properties. Learn about the formation, structure, and function of soil profiles, and how they vary across different regions and ecosystems. Explore the role of soil profiles in plant and animal life, and the human impact and conservation of soil resources. Soil structure refers to the arrangement and organisation of the particles in the soil, i.e., how sand, silt, clay, and humus bond together to form soil beds. Soil structure influences the soil ’s mechanical properties and can affect germination, root growth, tillage, overland traffic, and erosion. A diagram of soil profile provides a visual representation of the various layers of soil , providing information about their composition and characteristics. The diagram of soil class 7 explains the layers - topsoil, subsoil, and bedrock. Soil is one of the most important natural resources on earth. Soil content and quality vary from region to region.
