extracted from <a href=\"https:\/\/en.wikipedia.org\/wiki\/Leonardite\">leonardite<\/a>, a young oxidized lignite rich in <a href=\"https:\/\/en.wikipedia.org\/wiki\/Humic_acid\">humic acid<\/a>. It is used worldwide as a fertilizer raw material and plant biostimulant.<\/p>\n<p><strong>Extruded Potassium Fulvate Granules I<\/strong> is the grade built for one job: <strong>mixing into dry granular fertilizer without falling apart<\/strong>. Produced by hydraulic extrusion at 2\u20134 mm, it is the hardest and driest form we make.<\/p>\n<p>Two properties matter here. <strong>Crush strength<\/strong> \u2014 the granules survive the mechanical punishment of a bulk-blending drum, a conveyor drop and a bagging line without degrading back into fines. <strong>Low moisture<\/strong> \u2014 because the granule carries very little water, it blends with granular NPK without setting off the moisture migration that turns a blend into a solid mass.<\/p>\n<p>The result is a fulvate granule whose <strong>size and density closely match granular NPK<\/strong>, which is what stops the blend from segregating. A powder sifts to the bottom of the pile; a 2\u20134 mm extruded granule stays where you put it.<\/p>\n<p><strong>One operational rule, stated up front:<\/strong> once blended, use the blend promptly. The same low moisture that makes this grade stable on its own makes it eager to pull moisture from its surroundings in a blend. Do not warehouse a finished blend for months \u2014 see the note below.<\/p>\n<\/div>\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<div class=\"jf-grid\">\n<div class=\"jf-card\">\n<h4>High crush strength<\/h4>\n<p>Hydraulic extrusion produces a dense granule that resists attrition.

But in a blend it acts as a moisture sink, drawing humidity from the other components and from the air. Over weeks to months it softens and powders. Blend close to spreading and you never see the problem; warehouse a finished blend all season and you will.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>How is this different from the Micro Granule I?<\/summary>\n<p>Opposite ends of the spectrum. Micro Granule I is a hollow spray-dried granule designed to dissolve in seconds for liquid application. Extruded Granules I is a dense, hard granule designed to survive dry blending and dissolve slowly in soil. One is for the tank, the other for the spreader.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Will the granule break down into dust in my blender?<\/summary>\n<p>Very little. Hydraulic extrusion gives the highest crush strength in our range, and attrition losses in a standard drum blender are minimal. If you are running an unusually aggressive or long blending cycle, tell us and we will advise on the grade.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Is it still 100% water soluble if it is so hard?<\/summary>\n<p>Yes. Hardness and solubility are not in tension here \u2014 the granule is dense, but it is still fully soluble. It simply needs soil moisture or irrigation to work through it, which is the release pattern a basal application wants.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>What blending rate do you recommend?<\/summary>\n<p>10\u201325 kg per tonne of finished blend is the common range, depending on the humic content you want to claim on the label. Tell us your target spec and we will help you set the rate.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>What is the minimum order and lead time?<\/summary>\n<p>Made to order on an extrusion campaign. MOQ is higher than stocked powder and flake grades; typical lead time 15\u201325 days ex-works. Share your volume and we will quote firm numbers.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Do you supply a COA per

But in a blend it acts as a moisture sink, drawing humidity from the other components and from the air. Over weeks to months it softens and powders. Blend close to spreading and you never see the problem; warehouse a finished blend all season and you will.\"}}, {\"@type\": \"Question\", \"name\": \"How is this different from the Micro Granule I?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Opposite ends of the spectrum. Micro Granule I is a hollow spray-dried granule designed to dissolve in seconds for liquid application. Extruded Granules I is a dense, hard granule designed to survive dry blending and dissolve slowly in soil. One is for the tank, the other for the spreader.\"}}, {\"@type\": \"Question\", \"name\": \"Will the granule break down into dust in my blender?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Very little. Hydraulic extrusion gives the highest crush strength in our range, and attrition losses in a standard drum blender are minimal. If you are running an unusually aggressive or long blending cycle, tell us and we will advise on the grade.\"}}, {\"@type\": \"Question\", \"name\": \"Is it still 100% water soluble if it is so hard?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes. Hardness and solubility are not in tension here \u2014 the granule is dense, but it is still fully soluble. It simply needs soil moisture or irrigation to work through it, which is the release pattern a basal application wants.\"}}, {\"@type\": \"Question\", \"name\": \"What blending rate do you recommend?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"10\u201325 kg per tonne of finished blend is the common range, depending on the humic content you want to claim on the label.
