I seem to be better at rocks than tomatoes so far. What have been your experiences with Humic acid? I started researching this stuff a couple years ago and as I go along here I have found out that one of the places I collect really nice gypsum (Selenite) crystals is the same place they are getting Leonardite from. I figured I'd ask how your experiences have been good or bad with this product.

I have been using humic for well over a decade for pumpkins and for the last 10 years or so on tomatoes. Currently I use the WOW brand fulvic and humic.

Im trying it but I dont know. Amendments that might help.... you might try a bit of alfalfa? Idk. Depends what the soil needs I guess.

It can help chelate minerals, nutrients make them more available. Helps clean toxins, some use it every feeding in a diluted fashion. Humic is broke way down to usually over centuries from rich soil and no one really knows exactly what it is but is the Carbon in available form for micro-organisms to plants. Similar to a tonic for your soil. It can get things active more than previously. Microbes happy. soil happy, tomato happy. Studies show fulvic tends to work a little better in a foliar way. I know it's helped my garden start to get more balanced in nutrients from the sturation effect increasing. Hope this is helpful.
