Pedogenesis is the process of soil formation. It is a complex, multifaceted phenomenon driven by the interaction of five soil-forming factors: climate, parent material, time, topography, and organisms. Climate influences the rate of weathering and the type of vegetation that can grow, while parent material provides the basic mineral constituents of the soil. Time is crucial for the development of distinct soil horizons, and topography affects drainage and erosion. Organisms, including plants, animals, and microbes, contribute organic matter and influence soil structure and nutrient cycling.

The process of pedogenesis begins with weathering, the breakdown of rocks and minerals into smaller particles. This can occur through physical, chemical, or biological means. As weathering progresses, organic matter from decaying plants and animals accumulates, forming the initial organic horizons. Over time, various processes such as leaching, illuviation, and eluviation lead to the differentiation of the soil profile into distinct layers, or horizons, each with its own unique physical, chemical, and biological characteristics. These horizons typically include the O horizon (organic matter), A horizon (topsoil), B horizon (subsoil), and C horizon (unconsolidated parent material). The characteristics of a soil, including its texture, structure, color, and fertility, are a direct result of the pedogenic processes that have acted upon it. Understanding pedogenesis is vital for agriculture, forestry, environmental management, and understanding Earth's surface processes.
