Organic matter is a primary driver of soil productivity and is the foundation of functional soil biology. 1 Editors: The grouping of organisms into fauna and flora is a bit arbitrary at times, e.g., protozoa somewhat blur the distinction between animal and plant, Maintaining healthy soil biology is much more sustainable than traditional practices that rely on high levels of synthetic fertilizers and pesticides such as fungicides, insecticides, etc. Leading specialists provide critical reviews and assessments of their particular branches of soil biology, paying particular attention to functional aspects and biotic interrelationships whenever possible. xref

When these bacteria, fungi, and animals die, the living organisms in the soil eat the dead, creating organic matter. It is often said that a handful of soil has more living organisms than there are people on planet Earth.
