here's how to determine if there is air in the soil using a pot of soil, a container of water, and a rope:

1. Insert the rope into the soil, making sure it reaches the bottom of the pot.

2. Pour water into the pot until it is just below the soil surface.

3. Observe the container of water for any rising air bubbles over a few minutes.

Air bubbles indicate the presence of air pockets in the soil, while no bubbles suggest limited air.
