href='https:\/\/en.wikipedia.org\/wiki\/Leonardite' target='_blank' rel='noopener'>leonardite<\/a>, a young oxidized lignite rich in <a href='https:\/\/en.wikipedia.org\/wiki\/Humic_acid' target='_blank' rel='noopener'>humic substances<\/a>. It occupies a different point on the extraction spectrum from our Type I line: <strong>higher total humic acid (55% min), moderate fulvic acid (30% min)<\/strong>, and a more accessible price per tonne. Same mine. Different balance.<\/p>\n<p>Mineral Source Potassium Fulvate <strong>Flakes II<\/strong> is the flake form of our Type II line \u2014 <strong>2\u20133 mm shiny black flakes<\/strong> built for the same liquid-fertilizer and water-run applications as Type I Flakes, but at a different price point because the extraction pulls more <strong>humic acid (55% min)<\/strong> and less <strong>fulvic acid (30% min)<\/strong> from the same leonardite.<\/p>\n<p>What does that mean in practice? If your formulation targets <strong>soil structure improvement, cation exchange capacity (CEC) building, or organic-matter enrichment in soil conditioners<\/strong>, Type II delivers more humic acid per dollar spent. The trade-off is straightforward: you get less of the fast-acting fulvic fraction (which drives quick nutrient uptake and chelation) in exchange for a lower cost base and a heavier humic load that pays off over a growing season.<\/p>\n<p>These flakes are 99% water-soluble, dissolve with agitation, and carry near-zero dust \u2014 identical handling characteristics to Type I Flakes I. The difference is on the assay sheet and the invoice, not on the production floor.<\/p>\n<\/div>\n\n<div class=\"jf-sec\" id=\"benefits\">\n<style>.wp-block-kadence-advancedheading.kt-adv-headingkb-h2-benefits, .wp-block-kadence-advancedheading.kt-adv-headingkb-h2-benefits[data-kb-block=\"kb-adv-headingkb-h2-benefits\"]{font-style:normal;}.wp-block-kadence-advancedheading.kt-adv-headingkb-h2-benefits mark.kt-highlight, .wp-block-kadence-advancedheading.kt-adv-headingkb-h2-benefits[data-kb-block=\"kb-adv-headingkb-h2-benefits\"] mark.kt-highlight{font-style:normal;color:#f76a0c;-webkit-box-decoration-break:clone;box-decoration-break:clone;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;}.wp-block-kadence-advancedheading.kt-adv-headingkb-h2-benefits img.kb-inline-image, .wp-block-kadence-advancedheading.kt-adv-headingkb-h2-benefits[data-kb-block=\"kb-adv-headingkb-h2-benefits\"] img.kb-inline-image{width:150px;vertical-align:baseline;}<\/style>\n<h2>Key Benefits<\/h2>\n\n<div class=\"jf-grid\"><div class=\"jf-card\"><h4>Higher humic acid, better price<\/h4><p>55% humic acid minimum beats most competitors&#8217; standard grades, and it comes at a lower per-tonne cost than our Type I line because the extraction profile favors the higher-volume humic fraction over the more expensive fulvic concentrate.<\/p><\/div><div class=\"jf-card\"><h4>Same flake handling you already know<\/h4><p>2\u20133 mm flakes charge into mixing tanks without dust clouds, flow through screw feeders predictably, and don&#8217;t bridge in hoppers.

Type I pulls more fulvic acid (55% min) \u2014 ideal when you need fast chelation, quick uptake response, or high fulvic content on the label. Type II pulls more humic acid (55% min) \u2014 better value when your goal is soil conditioning, CEC improvement, or organic matter buildup, and you want to hold down raw-material cost. Pick by what your formula needs, not by guessing.<\/p>\n\n<\/details>\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Can I substitute Type II directly for Type I?<\/summary>\n\n<p>Chemically, not one-to-one \u2014 the fulvic content is almost half (30% vs 55%). If your formula&#8217;s performance depends on that fulvic fraction (e.g., a foliar spray where rapid uptake matters), you may need to adjust the inclusion rate or blend in a fulvic concentrate. For soil conditioners, bulk blends, and general-purpose liquid feeds, Type II often drops in with minor or zero reformulation.<\/p>\n\n<\/details>\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Is the heavy-metal profile the same as Type I?<\/summary>\n\n<p>Yes. Same raw material source, same refining route. All heavy metals test as not detected (Pb, As, Hg, Cd, Cr below detection limits per GB18877-2009).<\/p>\n\n<\/details>\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Why is the K\u2082O only 10% when Type I has 12%?<\/summary>\n\n<p>The extraction that maximizes humic acid leaves slightly less exchangeable potassium in the final product. If you need the extra 2% K\u2082O, look at our Sodium-Free Type II (15% K\u2082O min) or supplement with KCl\/MOP in your blend.<\/p>\n\n<\/details>\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>What is the minimum order quantity?<\/summary>\n\n<p>Stocked item in standard pack sizes. MOQ varies by destination \u2014 tell us your port and annual volume and we quote accordingly. Lead time: 7\u201315 days ex-works for stocked orders.<\/p>\n\n<\/details>\n\n<\/div>\n<\/div>\n\n<div class=\"jf-sec\"

Type I pulls more fulvic acid (55% min) \u2014 ideal when you need fast chelation, quick uptake response, or high fulvic content on the label. Type II pulls more humic acid (55% min) \u2014 better value when your goal is soil conditioning, CEC improvement, or organic matter buildup, and you want to hold down raw-material cost. Pick by what your formula needs, not by guessing.\"}}, {\"@type\": \"Question\", \"name\": \"Can I substitute Type II directly for Type I?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Chemically, not one-to-one \u2014 the fulvic content is almost half (30% vs 55%). If your formula's performance depends on that fulvic fraction (e.g., a foliar spray where rapid uptake matters), you may need to adjust the inclusion rate or blend in a fulvic concentrate. For soil conditioners, bulk blends, and general-purpose liquid feeds, Type II often drops in with minor or zero reformulation.\"}}, {\"@type\": \"Question\", \"name\": \"Is the heavy-metal profile the same as Type I?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes. Same raw material source, same refining route. All heavy metals test as not detected (Pb, As, Hg, Cd, Cr below detection limits per GB18877-2009).\"}}, {\"@type\": \"Question\", \"name\": \"Why is the K\u2082O only 10% when Type I has 12%?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The extraction that maximizes humic acid leaves slightly less exchangeable potassium in the final product. If you need the extra 2% K\u2082O, look at our Sodium-Free Type II (15% K\u2082O min) or supplement with KCl\/MOP in your blend.\"}}, {\"@type\": \"Question\", \"name\": \"What is the minimum order quantity?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Stocked item in standard pack sizes.
