Other Inoculants
There are hundreds of new microbial inoculants coming onto the market. Some of the
important microbes are in EM, but a few others are showing promise. I haven't seen any re-
search that would lead me to believe they are better than EM, but they can provide many
benefits and they're making their way into similar inoculants, such as the ones I like from
Tainio Technology and Technique.
Azotobacter and Azospirillum are soil-dwelling, aerobic and facultative anaerobic mi-
crobes, some of which can fix nitrogen on their own, without needing a legume host. Per-
haps more important than the nitrogen, they also manufacture B vitamins, hormones and
many useful bioactive substances that both protect and feed plant roots.
Trichoderma is another kind of fungi that is receiving a lot of attention. They aren't my-
corrhizal, but they colonize plant roots, improve plant growth and are especially noted for
controlling nearly all types of soil diseases. They're present in all healthy soils and are of-
ten the most prevalent fungi. They can be purchased as an inoculant, as well.
