Water Conservation for Lawn and Landscape February 11, 2014 Print Friendly and PDF

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.
