<strong>spherical 2\u20134 mm granule<\/strong> at <strong>40% minimum <a href=\"https:\/\/en.wikipedia.org\/wiki\/Humic_acid\" target=\"_blank\" rel=\"noopener\">humic acid<\/a><\/strong>, 2\u20135% K\u2082O and <strong>80% minimum water solubility<\/strong>.<\/p>\n<p>Roundness is the whole point of this grade, and it buys three things. <strong>Uniform spreading<\/strong> \u2014 a true sphere flows consistently through a spinner or pneumatic spreader, giving an even distribution pattern, where an irregular particle gives streaks. <strong>Clean blending<\/strong> \u2014 the sphere matches the size band of standard granular NPK, so it stays distributed rather than segregating. And <strong>appearance<\/strong> \u2014 a uniform round black granule looks like a finished fertiliser rather than a raw material, which matters in a retail or branded product.<\/p>\n<p>The specification is close to our Compacted Granules grade. The difference is shape and the process behind it: disc granulation with a binder produces the sphere, roller compaction without a binder produces a harder oval. Choose Round Granule where roundness, uniformity and presentation matter; choose Compacted where hardness and blend interlock matter more.<\/p>\n<p><strong>Potassium Humate Round Granule<\/strong> is a base-fertilizer grade \u2014 drilled, broadcast or blended, releasing its humic fraction into soil moisture rather than dissolving in a tank.<\/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>True spherical granule for even spreading<\/h4>\n<p>A real sphere flows consistently through a spreader and gives an even pattern. Irregular particles bridge and streak, and the grower sees it in the crop.<\/p>\n<\/div>\n<div class=\"jf-card\">\n<h4>Matches granular NPK sizing<\/h4>\n<p>At 2\u20134 mm the granule sits in the same size band as standard MAP, DAP and urea, so it stays distributed through blending and transport rather than segregating out.<\/p>\n<\/div>\n<div class=\"jf-card\">\n<h4>40% humic acid, 80% soluble<\/h4>\n<p>A solid granular analysis. Most of the humic fraction releases into soil moisture, with a small insoluble residue that is normal for a granular grade.<\/p>\n<\/div>\n<div class=\"jf-card\">\n<h4>Uniform, premium appearance<\/h4>\n<p>Consistent round black granules look like a finished fertiliser. Useful for branded and bagged product where appearance carries value.<\/p>\n<\/div>\n<div class=\"jf-card\">\n<h4>Low dust and clean handling<\/h4>\n<p>Essentially dust-free. Better working conditions and no product lost to wind at the spreader.<\/p>\n<\/div>\n<div class=\"jf-card\">\n<h4>Handles the full logistics chain<\/h4>\n<p>Survives blending, bagging, palletising and spreading without breaking down into fines under normal handling.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"jf-sec\" id=\"specs\">\n<style>.wp-block-kadence-advancedheading.kt-adv-headingkb-h2-specs, .wp-block-kadence-advancedheading.kt-adv-headingkb-h2-specs[data-kb-block=\"kb-adv-headingkb-h2-specs\"]{font-style:normal;}.wp-block-kadence-advancedheading.kt-adv-headingkb-h2-specs mark.kt-highlight, .wp-block-kadence-advancedheading.kt-adv-headingkb-h2-specs[data-kb-block=\"kb-adv-headingkb-h2-specs\"] 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-specs img.kb-inline-image, .wp-block-kadence-advancedheading.kt-adv-headingkb-h2-specs[data-kb-block=\"kb-adv-headingkb-h2-specs\"] img.kb-inline-image{width:150px;vertical-align:baseline;}<\/style>\n<h2>Technical Specification<\/h2>\n<table class=\"jf-tb\">\n<thead>\n<tr>\n<th>Parameter<\/th>\n<th>Specification<\/th>\n<th>Test standard<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Humic acid (dry basis)<\/td>\n<td>40.0% min<\/td>\n<td>HG\/T 3278-2011<\/td>\n<\/tr>\n<tr>\n<td>Potassium as K\u2082O (dry basis)<\/td>\n<td>2.0 \u2013 5.0%<\/td>\n<td>GB\/T 33804-2017<\/td>\n<\/tr>\n<tr>\n<td>Water solubility (dry basis)<\/td>\n<td>80.0% min<\/td>\n<td>HG\/T 3278-2018<\/td>\n<\/tr>\n<tr>\n<td>Moisture<\/td>\n<td>20.0% max<\/td>\n<td>HG\/T 3278-2011<\/td>\n<\/tr>\n<tr>\n<td>pH (1:100)<\/td>\n<td>9.0 \u2013 10.0<\/td>\n<td>GB\/T 33804-2017<\/td>\n<\/tr>\n<tr>\n<td>Granule size<\/td>\n<td>2 \u2013 4 mm<\/td>\n<td>Sieve method<\/td>\n<\/tr>\n<tr>\n<td>Granule shape<\/td>\n<td>Round \/ spherical<\/td>\n<td>Visual<\/td>\n<\/tr>\n<tr>\n<td>Appearance<\/td>\n<td>Black round granule<\/td>\n<td>Visual<\/td>\n<\/tr>\n<tr>\n<td>Product code<\/td>\n<td>JFHA-KHA-G<\/td>\n<td>\u2014<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p class=\"jf-sub\">Specification values are guaranteed minimums on a dry basis, taken from the batch Certificate of Analysis and tested against the stated Chinese industry standards.

Round Granule is disc-granulated into a true sphere using a binder \u2014 better for spread uniformity and appearance. Compacted is roller-compressed into a harder oval with no binder \u2014 better for hard handling and blend interlock. If presentation and even spreading are your priorities, buy round; if hardness and rough handling are, buy compacted.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Can it be used through drip irrigation?<\/summary>\n<p>It can be dissolved, diluted 500\u2013800 times, filtered and applied by root irrigation, which is a listed use. But if fertigation is your main route, a fully soluble powder or flake is the right product \u2014 a granular grade will always carry some residue and is not designed for fine emitters.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Will it segregate when blended with NPK?<\/summary>\n<p>Less than an irregular particle will, because the 2\u20134 mm sphere sits in the same size band as standard granular NPK. That said, every blend line behaves differently \u2014 run a segregation test on your own equipment before committing to a large run. We can supply a sample for that trial.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Is direct contact with seed safe?<\/summary>\n<p>Avoid it. Drill so the granule mixes into soil at 10\u201315 cm depth rather than sitting with the seed. The material is alkaline at pH 9.0\u201310.0, and concentrated humate against seed can affect germination. This is standard practice for any humic base fertilizer, not a peculiarity of this grade.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>What happens to the 20% that is not soluble?<\/summary>\n<p>It remains as a fine insoluble humic residue in the soil. It is not a problem \u2014 insoluble humic material is a legitimate soil amendment in its own right and continues to contribute to soil organic matter and structure.
