Tiger HumiK

Tiger HumiK
Jointly-Developed with
HGS BioScience

It provides plant nutrient sulphur along with functional carbon (humic acids). The humates are sourced from the highest quality leonardite. Unlike other sources of functional carbon, leonardite produces a more bioactive form of humic acid due to the presence of more phenolic and carboxylic functional groups. The analysis of Tiger HumiK contains Sulphur, Humic Acid, and Bentonite. Application rates should follow agronomist suggestions based on crop requirements, soil, and plant tissue sample analyses. 



Elemental Sulphur

  • Required for nitrogen fixation
  • Enhances nitrogen use efficiency
  • Essential for protein synthesis
  • Improves availability of phosphorus and some micronutrients


  • Adding bentonite to elemental sulphur increases water absorption of the pastille causing swelling and fracturing into smaller sulphur particles
  • Smaller sulphur particles provide greater surface area for bacteria to feed on the sulphur and convert to plant available SO4


Humic Acid

  • Improves soil health and structure
  • Co-transports micronutrients

Fulvic Acid

  • Chelates molecules and transports micronutrients
  • Carries bioactive molecules into the plant
  • Small molecular size contributes to effective absorption by plant
