Answer Details

The process of removing soluble substances such as mineral salts from the topsoil into lower layers of the soil is called "leaching." This process occurs when excess water, often from rainfall or irrigation, moves through the soil, carrying with it the dissolved minerals and nutrients. These soluble substances are transported downwards and deposited in the lower layers of the soil, making them less available to plant roots in the topsoil. This can have both positive and negative effects on plants and the environment. While leaching can help to prevent the accumulation of excess nutrients, it can also lead to a loss of valuable minerals from the topsoil, reducing soil fertility and plant growth.
