Fulvic acids are the smallest, lightest molecular-weight components of “humic acids”. They are acid chains/conglomerate molecules. As created by nature, the very small, low molecular weight humic components (“fulvic acids”) are originally created by soil-based micro-organisms (“SBO’s”) which, in turn, make minerals and other nutrients assimiliable by plants. Millions of years ago (and today) SBO’s consume the decayed plant organic matter in the humate deposits and the organisms subsequently excrete a waste material (digested decayed plant organic matter) back into the earthy material. The cycle continues over and over, on and on – nature’s own natural chelation process.
The complex photosynthetic reactions – produced in all plants – produce the nutritional components needed for all the various parts of the plants. Muco-polysaccharides (a class of carbohydrates such as starches and cellulose) flow throughout the plant as nourishment and some of this is returned to the roots where the soil-based micro-organisms are re-nourished to produce (excrete) additional digested humic components which combines with minerals and other nutrients in the soil to continue the cycle.
Fulvic acids are a biologically active mixture of weak aliphatic* and aromatic organic acids which are soluble in water and all pH conditions (acidic, neutral, and alkaline). Fulvic acids are the smaller and lighter weight (molecular weight) parts of humic acids having molecular weights which range from approximately 2,000 or less”.
