   The arrangement of these horizons in a soil is known as a soil profile. Soil scientists, who are also called pedologists, observe and describe soil profiles and soil horizons to classify and interpret the soil for various uses. Soil horizons differ in a number of easily seen soil properties such as color, texture, structure, and thickness.

   The word “soil” has been defined differently by different scientific disciplines. In agriculture and horticulture, soil generally refers to the medium for plant growth, typically material within the upper meter or two (Figure 1). We will use this definition in this chapter. Soil consists predominantly of mineral matter, but also contains organic ma...

   Soil is important to our society primarily because it provides the foundation of agriculture and forestry. Of course, soil is also a critical component for terrestrial ecosystems, and thus important to animals, plants, fungi, and microorganisms. Soil plays a role in nearly all biogeochemical cycles on the Earth’s surface. Global cycling of key elem...

   The fundamental factors that affect soil genesis can be categorized into five elements: climate, organisms, relief, parent material, and time. One could say that the relief, climate, and organisms dictate the local soil environment and act together to cause weathering and mixing of the soil parent material over time. As soil is formed it often has ...

   Dec 13, 2023 · A Soil Profile is a vertical section of the soil that shows its various layers or horizons. Over time, as soil matures, layers (or horizons) form a soil profile. A model of soil profile explains the horizons in a better manner. These horizons, from top to bottom, are labeled as O, A, E, B, and C horizons.

   Three classes are used plus nonstructural grades. 1 - Weak: The peds are barely observable in place. When gently disturbed, the soil material parts into a mixture of entire and broken peds and much material that exhibits no ped faces. 2 - Moderate: The peds are well formed and evident in undisturbed soil.

   What are horizons in a soil profile?

   • A model of soil profile explains the horizons in a better manner. These horizons, from top to bottom, are labeled as O, A, E, B, and C horizons. The most fertile part of the soil profile is typically the A horizon, also known as topsoil. The soil profile stretches out right from the soil surface to the parent rock material.

   Why is soil profile important?

   • The study of the soil profile is crucial because it serves as a historical record of all the processes that have formed the soil and serves as the foundation for pedagogical research. The thin layer of material that covers the surface of the Earth is called soil, and it is created as rocks weather.

   How deep is a soil profile?

   • Usually, a soil profile is examined down to a depth of around five feet. The soil at the top of the cross-section is always dark, whereas the soil below seems to be lighter in colour. Soils are porous natural bodies made up of organic and inorganic matter and are the structural and functional basis of terrestrial ecosystems.
