Which of the following types of soil has the highest water-retaining capacity?
Answer Details
Among the given options, clay soil has the highest water-retaining capacity. This is because clay soil has very small soil particles with spaces in between them, which can hold onto water molecules tightly due to the electrostatic forces between the particles and water molecules. As a result, water is absorbed and retained in the soil for a longer period, making clay soil ideal for farming and gardening. On the other hand, sandy soils have large particles with gaps between them, which allow water to pass through easily, causing less retention of water in the soil.
