Testing for Soil Compaction:- Use a Soil Probe

- Low-Tech: Use a wire-flag

- How deep can you push it into the ground?

- How much resistance?

- Is the soil hard, rocky, soft, grainy?

How to Make Compacted Soils in 30 minutes or less:

1. Drive on it with a heavy, wheeled loader.

2. Increase effectiveness by doing this when its wet
