Why are humic substances sometimes called Leonardite?
True Leonardite comes from the hills of the Dakotas and was discovered by Dr. Leonard. Over time the name became confused with all humic substances, and lack of standardization has continued the misnomer. The humic substances found in this area are low in fulvic acid (the lowest molecular weight) but high in humic acid content. The low fulvic portion is because of the geological uplift and cracking which allowed the material to become weathered, literally rinsing out the fulvic portion. (akin to leaving your compost in the rain for thousands of years). Additionally, the source material for this humic substance was formed in the presence of salt water marshes. While it will provide benefits to the soil, we prefer a source that is high in humic and fulvic acid. This means the source has not been leached or weathered and was made in the presence of fresh water where cycads and other leafy greens were growing. We have searched the world over, tested substances from many continents and foun
