Humate: Humate is a generic name for humic materials - salt forms of humic acid. They are most commonly low grade lignite coal. Humates regulate water-holding capacity, have extremely high ion exchange capacities, and reduce soil erosion by increasing the cohesive forces of the very fine soil particles. Very low concentrations of humates have been shown to stimulate seed germination and root growth. They have also been shown to stimulate desirable soil microorganisms. The percentage of humic acid in a humate will vary from product to product. Humates may be made into liquid form or used in the dry form. Analysis test done at a competent lab found Hou-Actinite lower in lead and arsenate.
