A soil profile refers to a vertical cross-section of various layers of soil. Typically, soil consists of three horizontal layers, namely the topsoil, subsoil, and bedrock. Each layer possesses distinct characteristics, such as texture, color, depth, and chemical composition. These layers are referred to as horizons, which are formed through ...There are five soil horizons: O, A, E, B, and C. (R is used to denote bedrock.) There is no set order for these horizons within a soil. Some soil profiles have an A-C combination, some have an O-E-B, an O-A-B, or just an O. Some profiles may have all the horizons, O-A-E-B-C-R. Jan 27, 2020 · “Soil consists of 45% minerals, 25% air, 25% water, & 5% organic matter” Source – US EPA. It is our planet that is providing plants with the help of soil and nutrients which are needed to grow and a kind of interactive relationship with microbes and fungi which will help them to enter and take up nutrients. These different layers are called soil horizons. A soil profile is a vertical slice of the soil that shows the different layers. Each layer is different both physically and chemically. Each horizon is named and defined. O Horizon – consists of the organic matter such as fallen leaves or decomposed plants at the very top of the soil profile. Such a vertical section of soil is called a soil profile. The soil profile makes up of successive horizontal layers each of which varies in thickness, colour, texture, structure, acidity, porosity, and composition. In mineral horizons (A, B, and C-horizons) and parent rock or R-horizon. Soil profile.A soil profile consists of a clay layer underlain by a sand layer, as shown in Figure.
