Clay soil has small particles that are closely packed together, which creates a high density and low porosity soil. This means that the soil particles have a high attraction to each other, and they hold onto water tightly, making it difficult for water and air to move through the soil. This can lead to waterlogging, a condition where water accumulates on the soil surface, making it difficult for plant roots to breathe and grow. The property of clay soil that prevents it from supporting thick vegetation is its tendency of becoming waterlogged.
