Step 1: Understand what drainage capacity means. It refers to how well soil can allow water to pass through it.
Step 2: Identify the types of soil being compared: clay and sandy soil.
Step 3: Know that clay soil has very small particles that are tightly packed together.
Step 4: Realize that because of the small particle size, clay soil holds water and does not let it drain easily.
Step 5: On the other hand, sandy soil has larger particles with more space between them.
Step 6: Understand that this space allows water to flow through sandy soil more easily.
Step 7: Conclude that since clay holds water and drains poorly, it has a lower drainage capacity compared to sandy soil.
