Information booster: Pedology deals with soil horizons, soil profiles, and soil-forming processes under different environments. It helps in developing soil classification systems that are useful for land use planning and management. Pedological studies consider climate, organisms, relief, parent material, and time as soil-forming factors. Knowledge of pedology is essential for sustainable agriculture and soil conservation practices.
