The organic matter layer contains dead plants and animals materials, decayed, decaying organic matter (Humus). This is usually dark in colour. WebThe process of soil development is known as Pedogenesis. The major factors responsible for soil formation include parent rock material, relief (topography), climate, organic activity and time. All these factors play an important role in determining the texture, composition and colour or the appearance of the soil.
