HumaKelp is a formulation humic acids and Kelp derived from bull kelp (Durvillaea potatorum). The formulation ensures maximum benefit of highly active humic acids and of the natural plant growth stimulants such as auxins and cytokinins.

Soil application of HumaKelp maximises the benefits of humate (increased fertilizer responsiveness and soil moisture retention), with stimulation of prolific feeder-root formation through the action of auxins and amino acids in the Kelp extract.

HumaKelp has the potential to provide the following benefits:

  • Improved nutrient availability and fertilizer responsiveness, with reduced leaching losses (on sandy soils)
  • Increased soil moisture retention
  • Promotion of beneficial micro organisms
  • Accelerated root growth


Soil: 7-20L per hectare. Dilute with water 1:100 prior to use.

When mixing with other liquid fertilizers, test for compatibility with a small quantity in a jar.


20L, 200L, 1000L containers.
