<a href=\"https:\/\/en.wikipedia.org\/wiki\/Humic_acid\" target=\"_blank\" rel=\"noopener\">humic acid<\/a><\/strong>, <strong>10% minimum K\u2082O<\/strong>, <strong>97% minimum solubility<\/strong>, and a distinctly lustrous black crystal that looks like nothing else in the range.<\/p>\n<p>Two reasons customers pick it. The first is <strong>specification<\/strong> \u2014 at 65% humic acid with 12% maximum moisture, this is the most concentrated, driest soluble humate we make. The low moisture content means you are buying active material rather than water, which matters when you are comparing price per unit of humic acid rather than price per tonne.<\/p>\n<p>The second is <strong>appearance<\/strong>, and it is not a trivial consideration. In a retail bag, in a clear container, or on a trade-show table, the crystal looks like a premium input. Several of our customers sell into markets where the buyer inspects the material before agreeing a price, and a glossy black crystal simply performs better in that moment than a matte powder or flake.

It is normal for this grade, it is stated on the specification, and it is harmless in soil or in any properly filtered system. If you need absolute 100% solubility with zero residue, use the powder grade.<\/p>\n\n<\/details>\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Should I buy 1\u20132 mm or 2\u20134 mm?<\/summary>\n\n<p>1\u20132 mm dissolves faster and looks finer and more uniform in a small retail pack. 2\u20134 mm handles more easily in bulk and has stronger visual impact in a large container or a demonstration jar. For fertigation and plant use, 1\u20132 mm is usually the practical choice; for retail presentation, 2\u20134 mm is often preferred.<\/p>\n\n<\/details>\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Is the shine natural?<\/summary>\n\n<p>Yes \u2014 it is a property of the crystal structure produced under our process conditions, not a coating or an additive. That matters, because some &#8216;shiny&#8217; humates on the market are surface-treated, and the lustre disappears once the material is handled or dissolved. Ours does not.<\/p>\n\n<\/details>\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>How does the price compare on humic acid content?<\/summary>\n\n<p>Per tonne it is more expensive. Per kilogram of actual humic acid the gap is much smaller, because you are getting 65% against 60% and 12% moisture against 15% \u2014 you buy less water and more active material, and you pay freight on less water too. We are happy to run the numbers against your landed cost.<\/p>\n\n<\/details>\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Will it work through drip irrigation?<\/summary>\n\n<p>Yes, with normal filtration. Dissolve fully in a stock tank, allow any minor residue to settle, and filter as standard practice.
