The Soil Profile

The Soil Profile
  • The Soil profile consists of the weathered material derived from the rock, But the bedrock itself does not form a part of it.
  • A soil profile generally has three main horizons in it-true soil at the top, subsoil and the bedrock apart from it.
  • Each horizon is quite distinct from the others by its own physical and chemical composition and organic contents producing the long process of soil formation.
  • Each soil type has physical properties like its colour, texture and the structure.
  • They largely depend upon the nature of the bedrock from which they are derived.
  • There are five soil forming factors-bedrock, local climate, plant and animal organisms, elevation and the relief.
