This high quality leonardite outperforms competing products.

These granules are ideally suited for addition with granular fertilisers, but they can also be readily dissolved to make a liquid that can be added to dissolved urea. The solubility of these granules facilitates a successful fusion with fast-release fertilisers, which is particularly important for reducing the lock-up rate of dry-applied soluble phosphate sources, stabilising urea, chelating and complexing minerals, and buffering high sodium and heavy metalsKey Performance

  • Humic acid is a powerful fungi promotant.
  • Stabilize nitrogen and improve nitrogen efficiency (ideal as an additive with urea).
  • Promotes root growth.

Application Rates

Application Rate
Broadacre Planting Blends
5 - 15kg per hectare
General Purpose 
5% of total blends – i.e., 5 kg of NTS Soluble Humate Granules ™ with every 100 kg of urea, DAP/MAP etc, but do not exceed 20 kg/ha when banded or 50 kg/ha when broadcast



To produce a 6% potassium humate liquid, add 1 kg of NTS Soluble Humate Granules™ to a bucket containing a small quantity of water and make up to 10 L with water. Agitate vigorously. 10 - 15% 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%).


NTS Soluble Humate Granules™ have the potential to stain certain surfaces e.g. tiles, pavers. Avoid use around these areas.

Keep in a cool, dry place away from direct sunlight
