Humic/Fulvic Acid along with Kelp is a cornerstone of all things good, of all things Organic. Humic Acid (Humates) is carbon and carbon is the building block of all life. We put Humic/ Fulvic Acid or Humates in all that we make as we believe it to be absolutely essential. Our Humic Acid Complex feeds the beneficial microbes that live in the soil and as those numbers increase we see soil re-structured for the betterment of plants.
Humic/Fulvic Acid Complex – All Organic Spray
Extracted from natural, aged deposits of leonardite coal, our Humic/Fulvic Acid Complex contains highly concentrated soluble forms of both humic and fulvic acids. As such you get a very powerful catalyst used by professionals all over the world to increase microbial populations (especially fungi), improve soil structure, make fertilizers and pesticides work better, remove toxins and salts, and to buffer the soil pH.
Humic/Fulvic Acid Complex also stimulates root growth, chelates essential minerals, and enhances their absorption through both roots and leaves. It supplies over 47 trace minerals, loosens compacted clay soils to improve oxygen flow, and strengthens aggregate structure in sandy soils increasing the soil’s cation exchange capacity (CEC) for better nutrient retention. A truly remarkable product that’s also cost-effective to use.
The Humic/Fulvic Acid Complex is completely safe, non-burning, and beneficial to all plants and soil types.
