What are mycorrhizal fungi?

Mycorrhiza are microscopic organisms that form a symbiotic relationship with the roots of plants. Mycorrhiza are present on over 92% of the plant families that have been studied on earth. The earliest record of mycorrhizal presence is over 400 million years old.

What are the different types of mycorrhizae?

 

There are 3 major types of mycorrhizae. They are 1) Endo or Arbuscular mycorrhizae (which exist on 85% of the plant families), 2) Ecto mycorrhizae (which exist on 10% of the plant families (mostly woody plants), and 3) Ericoid mycorrhizae (which exist on less than 5% of the plant families). There are several other more obscure forms of mycorrhizae, but they are highly specific and not used from a commercial perspective.

How do I know which Santiam Organics products to use on my plants?

 

The general answer is that most plans will benefit from Santiam’s Endo products. If your use is on pine, fir, birch or some other tree, you more than likely should use Ecto products. For Rhododendron’s, azaleas, blueberries, and other plants belonging to the ericaceous family, use Santiam’s Ericoid products. As a note, Santiam Organics is the ONLY company in North America to produce its own ericoid mycorrhizae.

Is there a shelf life to Santiam Organics products?

As long as the storage info on the Santiam label is followed, mycorrhizae have been shown to survive for many years.  Generally, Santiam Organics products must comply with registration limitations that are dictated in each jurisdiction.

What are Mycorrhizosphere, Hyphashpere, and Rhizosphere

 

The Mycorrhizosphere is the region around a mycorrhizal fungus in which nutrients released from the fungus increase the microbial population and its activities.

 

The Hyphasphere refers to the region of soil around roots that are influenced by the presence of mycorrhizae.

 

The Rhizosphere is the narrow region of soil that is directly influenced by root secretions and associated soil microorganisms.
