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>Mineral Source Potassium Fulvate <strong>Powder I<\/strong> is the fine-mesh grade of our leonardite-derived fulvate, engineered specifically for <strong>fertilizer manufacturers and blenders<\/strong>. At 80\u2013100 mesh, the powder delivers maximum contact surface, dispersing evenly through an NPK blend instead of separating out during transport.<\/p>\n<p>Extracted from high-grade lignite and solubilised with potassium hydroxide, it guarantees <strong>55% fulvic acid<\/strong> and <strong>12% K\u2082O<\/strong> on a dry basis, dissolving <strong>100% in water<\/strong> with no residue. Unlike generic humate powders that flocculate in hard water, Powder I holds a flocculation limit of <strong>350 mg CaO per litre<\/strong>, staying stable in calcium-rich irrigation water and in UAN blends.<\/p>\n<p>If your line produces compound fertilizer, bulk-blended NPK, or a private-label water-soluble formula, this is the grade that meters cleanly, blends uniformly, and dissolves without clogging your equipment.<\/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>Blends without segregation<\/h4>\n<p>80\u2013100 mesh particle size matches the fineness of MAP, DAP and urea powders, so the fulvate stays evenly distributed instead of sifting to the bottom of the bag or pile.<\/p>\n<\/div>\n<div class=\"jf-card\">\n<h4>Highest fulvic acid in the Type I family<\/h4>\n<p>55% fulvic acid guaranteed \u2014 the shortest carbon chain and the most biologically active fraction, absorbed by roots and leaves within hours.<\/p>\n<\/div>\n<div class=\"jf-card\">\n<h4>Stable in hard water and UAN<\/h4>\n<p>Flocculation limit 350 mg CaO\/L.

Powder (80\u2013100 mesh) wets faster and blends more uniformly into compound fertilizer. Flakes (2\u20134 mm) generate almost no dust, flow better through dosing equipment and are preferred for liquid fertilizer production. Choose by your process, not by chemistry.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Can it be blended directly with urea or DAP?<\/summary>\n<p>Yes. Powder I is routinely blended with urea, MAP, DAP, MKP and potassium sulphate. Add at 5\u201310 kg per tonne of finished blend and run it through the normal blending cycle. Because the particle size is close to these carriers, separation during transport is minimal.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Will it clog my drip lines?<\/summary>\n<p>Not when handled correctly. Powder I is 100% water soluble, but always pre-dissolve it in a small tank and filter before it enters the drip system. This one step removes any undissolved grit and is the standard practice on every professional farm we supply.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Is it stable in hard water?<\/summary>\n<p>Yes \u2014 that is a defining property. The flocculation limit is 350 mg CaO per litre, well above what most irrigation water contains. Standard potassium humate flocculates and drops out; Powder I stays in solution.<\/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>Standard stock item. MOQ is one pallet for stocked packaging; lead time is typically 7\u201315 days ex-works, faster for repeat specifications. Custom packaging and private labelprinting are available on request.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Do you provide a COA with every shipment?<\/summary>\n<p>Yes. Each batch ships with a Certificate of Analysis showing tested values for fulvic acid, humic acid, K\u2082O, pH and heavy metals, referenced to the HG\/T and GB\/T test methods. We also hold third-party SGS reports on file.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Is it allowed in organic farming?<\/summary>\n<p>Our fulvic acid line is CERES organic certified to NOP standard.

Powder (80\u2013100 mesh) wets faster and blends more uniformly into compound fertilizer. Flakes (2\u20134 mm) generate almost no dust, flow better through dosing equipment and are preferred for liquid fertilizer production. Choose by your process, not by chemistry.\"}}, {\"@type\": \"Question\", \"name\": \"Can it be blended directly with urea or DAP?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes. Powder I is routinely blended with urea, MAP, DAP, MKP and potassium sulphate. Add at 5\u201310 kg per tonne of finished blend and run it through the normal blending cycle. Because the particle size is close to these carriers, separation during transport is minimal.\"}}, {\"@type\": \"Question\", \"name\": \"Will it clog my drip lines?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Not when handled correctly. Powder I is 100% water soluble, but always pre-dissolve it in a small tank and filter before it enters the drip system. This one step removes any undissolved grit and is the standard practice on every professional farm we supply.\"}}, {\"@type\": \"Question\", \"name\": \"Is it stable in hard water?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes \u2014 that is a defining property. The flocculation limit is 350 mg CaO per litre, well above what most irrigation water contains. Standard potassium humate flocculates and drops out; Powder I stays in solution.\"}}, {\"@type\": \"Question\", \"name\": \"What is the minimum order and lead time?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Standard stock item. MOQ is one pallet for stocked packaging; lead time is typically 7\u201315 days ex-works, faster for repeat specifications. Custom packaging and private labelprinting are available on request.\"}}, {\"@type\": \"Question\", \"name\": \"Do you provide a COA with every shipment?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes. Each batch ships with a Certificate of Analysis showing tested values for fulvic acid, humic acid, K\u2082O, pH and heavy metals, referenced to the HG\/T and GB\/T test methods.
