A soil profile refers to the

A soil profile refers to the vertical section of the soil, from the surface to the underlying rock, that shows the different layers (horizons) of the soil. Soil horizons are distinct layers of soil with different physical, chemical, and biological properties that develop over time due to various soil-forming processes. These horizons are arranged in a vertical sequence and can be observed and analyzed by digging a soil pit or hole. The soil profile provides important information about the soil's physical and chemical properties, such as texture, structure, pH, nutrient content, and organic matter content. This information is useful in agriculture, forestry, and environmental science for understanding soil fertility, soil erosion, and land management practices. The zone of eluviation is a specific horizon within the soil profile that refers to the layer where minerals and organic matter are leached or washed out of the soil by water movement.
