"There are living components in soil such as microorganisms, bacteria, fungi, insects, worms and even mammals," said Neil Dominy, Nebraska State Soil Scientist. "The inert material-the minerals-are not alive. But everything around that inert material and within that system is living."
What's the difference between soil and dirt?
Dirt, on the other hand, is mobile. "Dirt is what's on the road, the bottom of your shoes or in the air. It's out of place," Dominy said.
