Soil Vs. Dirt: What is the difference?
Date: March 29th, 2011
Soil contains microorganisms, decaying organic matter, earthworms and other insects. Soil is a living environment. The earthworms and insects aerate the soil and add to the organic matter of the soil through their waste and when their bodies decay.
Soil on the left, dirt on the right...you can see the difference!
Dirt is basically dead soil. It does not contain any of the above. You can add organic matter (compost) to dirt to revitalize it. The organic matter will provide food for beneficial microorganisms so that the ecological system can start to regenerate.
