Que Es El Suelo

Soil is a complex mixture that forms the outer layer of the Earth. It is the product of weathering processes acting on rocks and sediments, and contains minerals, organic matter, water, and air. When a soil profile is examined, distinct horizontal layers called horizons can be seen, which differ in color, structure, and chemical composition. The topsoil A horizon contains the most organic matter, while subsoil B horizons below contain fewer nutrients and clays. Soil types and profiles can vary significantly depending on the underlying geology and climate of the location.
