Our core philosophy is sustainable agriculture with an emphasis on optimising the physical, chemical and biological properties of soils. Our foremost challenge is to manufacture organic based soil conditioners and fertilizers that maximise and sustain soil productivity for the benefit of our customers.

The Omnia Group (parent) is a fundamental producer of a wide range of fertilizers. Our manufacturing plant and warehouse is in Morwell, Victoria. Omnia has expanded its Humate production capacity through investment in new plant and technology. Due to our access to unique quality of raw materials in Australia and our innovative product development, we have grown into the largest Australian manufacturer of natural humate based products.

We collaborate with Monash University and other Australian research institutions to develop new products and tools locally for use in Australia and worldwide; with the bounty of Australian talent and exceptional raw materials, our contribution to agriculture and research is significant.


Our range of products is vast and caters to a broad range of crops, soil types and application methods.
