anyone use fulvic acid before?

I searched and didn't see much but was wondering if anyone has experience using fulvic acid and/or humic acid.

Mel's Mix doesn't need either. I know humic acid is used on the dirt/soil in field growing.

thanks

another question I have and I didn't see in Mel's book(s) was....what is the year to year maintenance?

when you start the garden in year one and 1/3 of the volume is many different types of compost, well when do you start to replace the lost nutrients in the MM?  year 2, year 4?  I'm sure it must depend on the size of growth that takes place (ie - the more growth, the more nutrients that were removed from the soil).  But is there a general rule of thumb?

thanks

Compost is the source for both fulvic and humic acids.

Actually, the answer is in the book but not in straight forward terms as "year to year maintenance".  You add more compost.  Period.  You add more compost every time you plant, be it one square or a whole bed.  Add enough compost to bring the level back up to the original level in the bed.  During a long season, with hungry producers like tomatoes, you can just top dress with compost to maintain the depth of medium.

As a general rule, you don't have to add anything else if 5 different sources of compost are used.  I like adding something from the ocean, like kelp meal or diluted liquid kelp, for trace elements.  I envy Cape Coddess for all her free washed-up seaweed.  And folks on the East coast have crab, lobster or shrimp -based composts.  I personally buy crab meal and kelp meal from kelp4less.com and mix in a small teaspoon per square.  Needless to say, the bags last for a few years.  

I think you will find this book very, very interesting. Although a bit technical, one can really begin to see what happens in the MM.  A secret world.  Some of my beds are in use year around. https://squarefoot.forumotion.com/t20218-microbes-you-gotta-see-this-one?highlight=microbes
