The correct answer is option 3: Leaching. Leaching refers to the process of transferring minerals from the topsoil to the subsoil through soil-water. When water moves through the soil, it carries dissolved minerals with it and transports them downwards, gradually depositing them in the subsoil. This process is commonly observed in areas with high rates of rainfall or irrigation, where excessive water causes minerals to wash away from the topsoil. Leaching can result in a depletion of essential nutrients in the topsoil, affecting the fertility of the soil and potentially impacting plant growth. It is important to manage and replenish nutrients in agricultural practices to prevent excessive leaching and maintain soil productivity.
