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>Sodium-Free Potassium Fulvate Flakes I<\/strong> is our custom-manufactured grade for programmes where <strong>sodium is the enemy<\/strong>. Standard potassium fulvate is extracted with a potassium-sodium alkali blend and can carry residual sodium. This grade is made with a potassium-only route, and the difference shows in the analysis \u2014 and in the field.<\/p>\n<p>The numbers are the strongest in the family: <strong>15% K\u2082O minimum<\/strong> (against 12% in the standard grades) because there is no sodium competing for the exchange sites, alongside <strong>50% fulvic acid<\/strong> and <strong>50% humic acid<\/strong>. The flakes are a glossy 2\u20133 mm, and solubility measures 99% minimum.<\/p>\n<p>Where does it earn its premium? <strong>Sodium-sensitive crops<\/strong> \u2014 grapevine, strawberry, avocado, stone fruit, tobacco, potato and most berries, all of which accumulate sodium in leaf tissue and show burn, necrosis or yield loss. <strong>Closed and recirculating systems<\/strong> \u2014 hydroponics, glasshouse recirculation and any operation re-using drainage water, where sodium has nowhere to escape and builds up season after season. <strong>Saline and sodic soils<\/strong>, where adding sodium to an already sodic profile is the last thing the agronomist wants.<\/p>\n<p>This is a <strong>made-to-order grade<\/strong>, not a stock item.

That is why the K\u2082O guarantee sits at 15% rather than 12% \u2014 there is no sodium competing for the exchange sites. If your programme needs documented sodium figures, tell us at enquiry stage and we will provide the applicable test report.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Why is the pH window 9.0\u201312.0 rather than 9.0\u201310.0?<\/summary>\n<p>A consequence of the potassium-only route \u2014 no sodium alkali is used, so the resulting solution sits higher on the pH scale. This is normal for the grade and is not a quality issue. Do account for it if your formulation has a tight pH window.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Which crops really need the sodium-free grade?<\/summary>\n<p>Grapevine, strawberry, avocado, stone fruit, tobacco, potato and most berries are the classic cases \u2014 they accumulate sodium in leaf tissue and show tip burn, necrosis or yield loss. Also worth specifying for any closed hydroponic system and for saline or sodic soils.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Is it worth the premium over standard Flakes I?<\/summary>\n<p>If sodium is not a constraint in your programme, standard Flakes I is the better value \u2014 same agronomy, lower cost, in stock. Specify sodium-free when you have sodium-sensitive varieties, a closed system, or a sodic soil profile.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Is it a stock item?<\/summary>\n<p>No \u2014 it is made to order on a dedicated production campaign. Minimum quantity and lead time are agreed per order. Share your annual volume and we will build a supply plan with you.<\/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 batch?<\/summary>\n<p>Yes \u2014 fulvic acid, humic acid, K\u2082O, pH and the full heavy metal panel (Pb, As, Hg, Cd), tested to HG\/T and GB\/T methods.<\/p>\n<\/details>\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\">\n<summary>Can it be used in organic programmes?<\/summary>\n<p>Our fulvic acid line holds CERES organic certification to NOP standard.
