is there a reference number put to be used to say the obtained number of AMF spore per gram is low, medium or high? say for instance is 18 spore per gram of dry soil large or medium or small?
Researchers based on the below reference classified AM root colonization based on categories:
very high (.80%),
high (60–79%),
medium (40–59%),
low (20–39%)
and very low (1–19%).

I also investigated by myself the infection rate of mycorrhizal fungi in the saline soil which has about EC 8. the results were different based on the tea materials (phenol's) added with mycorrhiza to support it to be more active and abundant.
the reference is :

The minimum spore number which guarantees effective infection is 100 spores per plant. If your spore number is less than 100 per 100 grams I believe your level is low.

About 80 to 90% of plant species are mycorrhizal but within this grouping there is considerable variability in their dependency. Salwan provides very good information on root colonization which is measured by clearing roots staining for mycorrhizal fungi and then estimating the coverage. I imagine that as you have more susceptible dependent host mycorrhizal combinations the numbers of spores generated would multiple correspondingly. In a propagation system I was involved with the plants are inoculated with 100 spores to guarantee the infection and the increase from the inoculum was 7,000 fold. We inoculated bay grass seedlings and when the frost killed them the materials of growth substrate can be mixed in order to ensure vibrant infection in the next generation.

Apart from the spore density, the frequency and intensity of mycorrhization; the diversity indices (Shannon, Pielou, Simpson, etc.) also provide information on abundance
