Humic Acid or Fulvic Acid?


Which one Should you Choose?

With farmers making the shift to organic farming practices, we often encounter people facing the same decisions: should they use Humic Acid, Fulvic Acid or both? 

Liquid Fulvic and Humic

What is the difference?  What makes one better over the other? What kind of results can they expect using Humics and Fulvics? The answer to this really depends on what you are trying to achieve.

What's the difference?

These two organic acids both work in very different ways. The Humic acid molecules are too large to be absorbed by the plant, while the Fulvic acid is a smaller size, allowing it to be taken up by the plant. The Humic acid works in your soil to break down soil particles, increasing aeration, increasing water retention, boosting microbial activity and repairing damage made by chemical fertilizers. The Fulvic acid works in the plant to increase the pore sizes of the root system, enabling the plant to take up more and larger nutrients that are available in the soil.

Why choose one over the other?

So why would you want to use only one of these super acids and not the other? Farmers may be trying to achieve something more specific, like those using a hydroponic system. The Fulvic acid is preferred in hydroponics because there is no soil for the humic acid to work in. We can remove the Fulvic acid to be applied at a higher concentration and the hydroponic plants can absorb more nutrients. A Gardener may want to use the Humic Acid to build the microbial life in the soil, increase water retention, repair the soil structure, and create better chlorophyll synthesis; all leading to healthier plants and higher yields.

What is available out there?

You can purchase products such as Black Earth’s Organo Hume which contains both Humic and Fulvic acids. You can also purchase Black Earth’s Liquid Fulvic which has mostly Fulvic acid with small amount of humic acid still present. And then some other companies also sell products with humic acids only, but we don’t see the point in removing this value from a product.

Regardless of which product you choose, both the Humic and Fulvic acids are beneficial and should not be excluded from your inputs. It is a low cost, organic alternative to traditional fertilizers and will boost your yields and repair damaged soils.
