Soluble humic acid in versatile, user-friendly 0.2 – 1 mm particles.

This product is soluble and comprises around 95% potassium humate. These humates can be readily dissolved without the dust factor associated with humate powders. The rapid solubility of these granules facilitates a successful fusion with soluble fertilisers which is particularly important for stabilising urea, chelating and complexing elements and buffering high sodium and heavy metals.

Application Rates

Application Rate
Fertigation 2 – 4 kg
Foliar 500 g – 1 kg



To produce a 6% potassium humate liquid, add 750 g of NTS Super Soluble Humates™ to a bucket containing a small quantity of water and make up to 10 L with water. Agitate vigorously. Approximately 5% of the humates are insoluble; let sit overnight and then siphon the soluble fraction from the top (avoiding insoluble sediment resting on the bottom). The insoluble sludge remaining is a valuable addition to composts.

Application Rates for DIY Liquid Humus Liquid:

  • 2 – 10 L per ha (Foliar)
  • 20 – 50 L per ha (Fertigate)

Note: This 6% potassium humate recipe produces a concentrate with half the concentration of NTS Liquid Humus™ (12%).

Store in a cool, dry place away from direct sunlight

Product requires pre-mixing and sieving prior to application NOTE NTS Super Soluble Humates ™ have the potential to stain certain surfaces e.g. tiles, pavers. Avoid use around these areas
