Leonardite also known as "slack lignite" is really a waste material which is removed from the surface of lignite coal beds. It has a high "crude" humic acid content and essentially no Bio activity. It is widely used in industry and as a drilling mud but is not recommended for agriculture. Then why do so many manufactures use it to make liquid and soluble powders?

Only one answer I can think of "IT"S CHEAP" and "appears" to have a high humic acid content and this fools the public and when they try it and get little if any results and have to use ridiculously high rate, they then will say "HUMATES Don't WORK! and the cycle is stalled again. Only Fulvic acids make this stuff work and this compressed peat, not coal from New Mexico is true agricultural humate and is effective at 1.5 gm/20L. water in a foliar. Don't waste your time and money trying a save a few cents on a proven worthless concept. Notice the high levels mentioned in this article and don't be fooled by the "COAL Sellers"

most "liquid humic acid" really a salt of humic acids is made with Leonardite coal usually the recommendations are nearly 10 times the rate we recommend with Humisolve-USA, price per pound is only part of the story, the cost per acre is the key!
