Hi Jarel,
I dont use direct microscopy, but i have been using the soil microbiometer which now includes a F:B ratio. I am hoping to see a tracking towards a more fungal dominated ecosystem, but it would be even better to see an overall increase in both F & B numbers
Here is a post i did a while ago on facebook. I will have to do another test to update the numbers.
