I work part time at a nursery and one of the products that it has been encouraging is a product called Mykos, which is basically mycorrhizal spores which people are instructed to sprinkle under the roots of plants when they transplant, or to incorporate into their soil. I recently did some research on mycorrhizae and am very fascinated by it. I have come to the simple conclusions that:
1) Mycorrhizae is good (almost always, though in some cases like commercial corn production, it has the potential hurt the plant)
2) Mycorrhizae is already naturally occurring provided that the environment is right for it (ex. we don't till too much or use soilless or sterile potting mixtures)
The things I am less certain about are whether or not I would want to add mycorrhizae to my garden. I am very interested in using it with my vegetables, and I also have some ailing fruit trees, who I think could be helped by more mycorrhizae. So far, the two best articles I have read about mycorrhizae have contradicting conclusions about adding it.

Then there is this article by Chalker-Scott, https://puyallup.wsu.edu/~Linda%20Chalke ... rhizae.pdf . She writes:There are practical solutions to some of the mycorrhizal deficiencies in man-made environments and reintroducing mycorrhizal fungi in areas where they have been depleted can dramatically improve plant establishment and growth.
Perhaps they are not as contradictory because the first is saying that adding micorrhizae is good for plants that have been depleted and the second is emphasizing that plants in "real world" situations will not necessarily be depleted.scientific studies on urban landscapes and other â€œreal worldâ€ systems report that these products have no significant value. In general, plant species inoculated with commercial products and installed into the landscape are equal in performance to uninoculated controls (which quickly became colonized with native fungi). While the addition of organic matter has been found to stimulate growth of native mycorrhizal populations, applying commercial mycorrhizal amendments is generally ineffective and unnecessary, given the widespread presence of indigenous inoculum.
So my question is if anyone has used straight micorrhizae before? And what are people's thoughts about doing this? I know people have spoken about using fertilizers with micorrhizae and I have loved the discussion here about micorrhizae in general: https://www.helpfulgardener.com/forum/vi ... p?p=153450. However I still don't know what to think about adding it. I also want to know if I add it to my soil, whether I need to add more fertilizers because the plants will be accessing the nutrients in the soil more effectively?
I look forward to hearing your insights!
