I know and have done some sampling with Melissa. She has been absolutely amazing to deal with. She is quite knowledgable and will set you straight if need be.

The fulvic and humic testing has been eye opening. It is very informative on two levels.

On soil testing it will show you how your soil is feeding what organisms. Ours is very fuvlic vs humic which to me is bacterial and low fungi. It also signals the limiting factor of calcium availability in our soil. I can pretty much verify this through my own observations.

Secondly, her product testing on the humic acids is amazing. She can tell which ones have too much carbon. She can even tie that to your next soil test too. This is because a lot of humic acid products have the wrong carbon as their make up.
