About Biological Fertiliser

Discover the power of Biological Fertiliser to enhance soil fertility. Learn how these liquid fertilisers, used in conjunction with regenarative farming practices, can not only build biology in the soil, but promote a sustainably healthy, and productive eco-system.

SONIC Liquid Fertilisers are naturally fermented using Australian, wild harvested microorganism formulas, containing 100% natural cultures of beneficial bacteria, yeasts and fermenting fungi.

Fermentation is a process that has been utilised for centuries in various industries including the production of biological fertiliser, a soil amendment with both microbial fertiliser, and mineral fertiliser effects.

Cold fermentation converts compounds into soluble form.  The process captures all the minerals, trace elements, and amino chains, in a bio-available state.  Nutrients, then, become readily available for plants to uptake.

How Does Biologically Fermented Fertiliser Contribute to Soil Fertility?

Fermentation is the key to making biologically ‘alive’ fertilisers. The ‘living’ nature of biologically fermented fertiliser makes them unique compared to synthetic alternatives.

During the fermentation process, beneficial microorganisms break down organic matter into nutrient-rich compounds that can be easily absorbed by plants.  These microorganisms can also suppress harmful pathogens and pests, throughout the fermentation process..

By using these products fresh, we can harness the full potential of their biological integrity, and achieve optimal results in plant growth and agricultural productivity.

Biological Fertiliser and Natural Farming

Some of the functions and benefits of boosting microbes in the soil include;

  • Enhanced nutrient cycling
  • Improved plant immunity
  • Contributes to soil structure
  • Fix atmospheric nitrogen
  • Enriched ecosystems
  • Supports seed germination
  • Increased nutrient brix levels

How To Use Liquid Biofertiliser

SONIC Liquid Biological Fertiliser is highly effective when used as a seed treatment and in the earlier parts of the plant growth cycle.

From the early growth cycle, Biological Fertilisers are an excellent addition used regularly for maintaining plant strength and resilience in mid to advanced crops.  For pasture cropping and orchards, Biological Fertiliser is used as a foliar spray and soil drench.

Incorporating regenerative management strategies, such as multi-species planting and rotational grazing, can enhance the effectiveness of Biological Fertilisers, maximising soil health and crop yields.



Liquid Seaweed, Fish Hydrolysate, Liquid Probiotic Seaweed for Livestock

For Soil, Crops & Livestock

  • Seed Treatment – prepares seeds with beneficial microbes and seaweeds natural growth hormones.
  • Soil Conditioner – helps increase aeration, water holding capacity, and nutrient cycling.
  • Soil Mineraliser – offers naturally balanced organic minerals and microelements.
  • Bio-stimulant – chelated micronutrients readily available for plants and animals.
  • Foliar Spray – coats leaf in beneficial bacteria, leaving no space, or food, for pathogens.
  • Compost Activator – provides beneficial microbes to help speed the break down of compost.
  • Livestock Probiotic Minerals – delivers seaweeds balanced nutrients with natural probiotics to optimise digestion.



Many seaweed fertiliser products today are manufactured using an extraction process.  The extraction process generally uses an alkali extraction agent, such as potassium hydroxide.  This process inevitably denatures a lot of the original compounds found in seaweed, which are known to have many beneficial uses for plants.

For example, seaweed has a compound called betaine osmoregulators. When applied to plants, in its original form, these osmoregulators make plants a lot more resilient to drought stress.  It allows the plant cells to regulate water much better, and require less water, which enhances the plants’ tolerance to stress.  Betaine osmoregulators are lost using an alkali extraction method. 

Cold processing, or natural fermentation, retains all the original compounds of seaweed, in a bio-available state.
