href='https:\/\/en.wikipedia.org\/wiki\/Potassium_humate' target='_blank' rel='noopener'>potassium humate<\/a> into uniform 4\u20136 mm spherical granules. It is designed as a <a href='https:\/\/en.wikipedia.org\/wiki\/Fertilizer' target='_blank' rel='noopener'>bulk-blending<\/a> base material \u2014 not a standalone soluble product \u2014 delivering humic and fulvic acids in a form that mixes cleanly with granular NPK, urea, and MAP without segregation.<\/p>\n<p><strong>Potassium Humic Fulvic Round Granule<\/strong> is not a soluble fertilizer ingredient \u2014 it is a <strong>granular carrier and functional additive for bulk-blended fertilizers<\/strong>. Produced by <strong>disc granulation<\/strong> into uniform <strong>4\u20136 mm spherical granules<\/strong>, it is designed to be mixed physically into NPK, organic, or BB (bulk-blend) fertilizers as a <strong>humic-enriched base granule<\/strong> that releases its active fraction gradually in soil moisture.<\/p>\n<p>The numbers are different from our fulvate lines, and they should be: <strong>25% humic acid, 10% fulvic acid, 2\u20135% K\u2082O, and 70% water solubility<\/strong>. This is not a product you dissolve in a tank \u2014 it is a product you <strong>blend into a bag<\/strong> alongside MAP, DAP, urea, and other granular components, where it contributes humic substances to the rhizosphere over time as the granule breaks down in soil.<\/p>\n<p>The <strong>round shape and 4\u20136 mm size band<\/strong> are deliberate: they match the physical profile of standard granular NPK fertilizers, which means the humic granules <strong>don&#8217;t segregate during transport, bagging, or mechanical spreading<\/strong>. Your blend stays homogeneous from the blender to the field.<\/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>Size-matched to granular NPK<\/h4><p>4\u20136 mm round granules sit in the same size band as standard MAP, DAP, and urea prills.

Only about 70% is water-soluble, and the remaining 30% (the insoluble humic matrix) will settle out as sediment, clog filters, and cause problems in emitters. This product is designed for <strong>dry blending into granular fertilizers<\/strong>, not for dissolution. If you need a soluble potassium humate\/fulvate, look at our Type I or Type II flake\/powder grades.<\/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 fulvic acid only 10%?<\/summary>\n\n<p>The disc granulation process and the raw material mix for this product are optimized for <strong>granule strength and physical properties<\/strong>, not for maximizing fulvic acid yield. The 10% fulvic \/ 25% humic profile is what&#8217;s economically achievable in a disc-granulated form while keeping the price competitive as a bulk-blending additive. If you need higher fulvic content in a granular form, consider our Extruded Granules I (Type I, 50% fulvic).<\/p>\n\n<\/details>\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>How does this compare to Extruded Granules I?<\/summary>\n\n<p>Extruded Granules I (Type I): 50% fulvic \/ 50% humic \/ 10-12% K\u2082O \/ 100% soluble \/ 2-4mm matte granules \u2014 a premium soluble granule for high-value applications. Round Granule: 10% fulvic \/ 25% humic \/ 2-5% K\u2082O \/ 70% soluble \/ 4-6mm round granules \u2014 a cost-effective bulk-blending base. Different products for different jobs.<\/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 crush strength?<\/summary>\n\n<p>The disc-granulated round granules have good mechanical strength \u2014 they survive standard drum blending and conveyor handling without excessive breakage. If you need a specific crush strength number for your process (e.g., for a particular blender type), request it at enquiry stage and we&#8217;ll have it tested.<\/p>\n\n<\/details>\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Can this be used in organic farming?<\/summary>\n\n<p>Our raw material source (leonardite) is naturally occurring and the product is mineral-based.
