The three primary gases present in a healthy soil are oxygen, nitrogen and carbon dioxide. Plants use carbon dioxide to help with photosynthesis, a byproduct of which is oxygen, which is then used by animals in the soil. Nitrogen is an essential gas for plants to build proteins, perform photosynthesis and form DNA.
