Fertile soil is teeming with beneficial soil microbes. It is estimated that there could be billions of microbes in a gram of soil.
Bacteria, fungi, and protozoa are major players in soil microbial processes. They perform a variety of functions beneficial to soil and the plants growing in that soil. Other soil organisms of importance are nematodes, arthropods, and earthworms.
