Archaea, a recently identified microorganism found in some of the planet's most extreme environments, such as hydrothermal vents on the ocean floor. In garden applications, scientists have discovered that these microbes actually clean the soil, returning it to a healthier, more natural state. Jobe's Biozome contains a proprietary species of Archaea that quickly break-down complex hydrocarbons & minerals into basic nutrients & trace elements that plants readily absorb. Mycorrhizal fungi expands the surface-absorbing area of the roots by 100 to 1, 000 times, sending out filaments that act as extensions of the plant's root system, helping plants absorb more water & nutrients. In return, the fungi receive essential sugars & other compounds from the plant roots, fueling their own growth.
