Clay soils are composed of very fine particles that are tightly packed together. This makes them dense and heavy, which can lead to poor drainage and slow water movement. When wet, clay soils can become sticky and difficult to work with, while they can harden and crack when dry. These soils are often rich in nutrients, making them suitable for growing certain plants. However, their compact nature can limit root growth and make it challenging for some plants to thrive. Understanding the properties of clay soils is essential for effective gardening and agriculture.
