The Importance of Mycorrhizal Fungi and Other Beneficial Microorganisms in Biodiversity Projects
Ted St. John
1992: Fallen Leaf Lake, CA
Ecosystem processes are the combined activities
of a variety of microorganisms. The most important
functional groups include mycorrhizae, nitrogen fixers,
decomposers, plant growth promoting rhizobacteria,
pathogen—suppressive organisms, builders of soil structure
and of protective surface crusts. These organisms do not
reliably disperse to the nursery or to a planting site. They
require a focused inoculation program from stockpiled top
soil or from pre—inoculated plants. Current technology
allows introduction of mycorrhizae, nitrogen fixers, and
pathogen suppressive organisms. Other functional groups
may soon become available commercially.
