Australian Farmers
Want to Build Healthier Soil the Natural Way?
Feed your land with Liquid Fish and Seaweed Biological Fertilisers — packed with the organic minerals and microbes your soil needs to stay productive all year round.
From The Sea To Your Soil
Poor soil quality can hold back your farm’s potential, but for generations, fish and seaweed have been used to breathe new life into tired soil.
Here at SONIC Natural Farming, we’ve taken that old-school wisdom and combined it with cold fermentation and our proprietary starter cultures to create a naturally balanced mineral concentrate, equipped to deliver real long-lasting results.
Eco-Friendly Fertilisers You Can Trust
Relying on chemical inputs can take a toll on your farm. Biologically activated fertilisers provide a natural solution, delivering healthier, more sustainable results that benefit both your farm and the environment.

Noticed your soil’s not what it used to be?
It’s not that your farm isn’t working hard—it’s just that, over time, the land’s been pushed to its limits. Years of conventional fertilisers and farming practices have taken their toll, and your soil’s vitality may be fading.
When soil loses its health, it’s not just your crops that suffer—it impacts productivity, crop resilience, and the long-term wellbeing of your entire farm.
But here’s the good news: there’s a way forward.
Imagine nourishing your soil naturally, restoring its health and fertility, and watching your crops thrive again.
Our ocean-derived Liquid Fish and Seaweed Biological Fertilisers work with your soil — improving structure and boosting microbial activity without relying on harsh chemicals.
We’re not offering a silver bullet that will instantly repair your soil; we’re providing genuine crop nutrition, packed with beneficial microbes, that will build your soil health for the long term.

Biological Fertilisers FAQs
SONIC Liquid Fish and Seaweed Biofertilisers contain native microbial strains isolated from soils well-adapted to Australian conditions. These microbes enhance soil microbiology, support nutrient cycling, balance pH, and help remediate salt and chemical impacts. Fish and Seaweed Biofertilisers also deliver bioavailable organic minerals and trace elements essential for optimal crop growth.
Unlike NPK fertilisers, that just feed plants (synthetic) minerals, biological fertilisers work by delivering organic minerals and boosting the soil’s microbiome—improving nutrient cycling and plant immunity. This leads to stronger, healthier crops, without the potential of mineral imbalances or runoff that NPK fertilisers can cause.
| Feature | Natural Fertilisers (e.g., Fish Hydrolysate) | Synthetic Fertilisers (e.g., Urea) |
|---|---|---|
| Source | Derived from natural materials like fish byproducts, compost, or seaweed. | Manufactured from synthetic chemicals or mined minerals. |
| Nutrient Composition | Contains a broad spectrum of nutrients including NPK, amino acids, and trace minerals. | Primarily provides specific nutrients like NPK in concentrated forms. |
| Nutrient Release | Varies by application: Quick-release when used as a foliar spray (absorbed through leaves); slow-release when applied to soil, feeding plants over time via microbial activity. | Quick-release, providing immediate nutrients to plants but often lacking sustained availability. |
| Soil Health Impact | Enhances soil structure, increases microbial activity, and improves water retention. | Can degrade soil structure, reduce microbial life, and lead to long-term fertility decline. |
| Environmental Impact | Lower risk of runoff and pollution; supports sustainable practices. | Higher risk of leaching, runoff, and environmental harm. |
| Plant Growth | Supports balanced, resilient growth with improved flavour and nutrition; helps achieve higher nutrient density in crops. | May stimulate fast growth but can cause imbalances or fertiliser burn; does not support high nutrient density in plants. |
| Cost | Generally higher upfront cost; long-term savings through improved soil health and using DIY methods for production. | Lower cost; requires more frequent application, as land often becomes dependent on increasing amounts each year, raising costs over time. |
| Application Frequency | Initially applied more frequently to activate soil biology, then less often as natural ecosystems restore balance and fertility. | Frequent applications required to sustain growth; dependence increases over time, creating a perpetual input cycle. |
| Compatibility with Regenerative Practices | Highly compatible; supports biodiversity, carbon sequestration, and soil restoration. | Small amounts may offer a temporary boost, but over time, become unnecessary as regenerative practices and natural inputs rebuild the soil. |
Naturally fermented liquid products, begin working immediately by activating soil biology and delivering bio-available nutrition to plants. Results will vary depending on your crop, soil, and growing practices. For grazing pastures, in poor condition, improvements in soil biology may take a few years to fully develop. When seeding, you can often see faster seed germination and stronger early growth. Orchard and vegetable growers typically notice improved growth, flavour, nutrient-density, and a longer shelf life.
Liquid seaweed extracts are chemically-extracted or heat-extracted to concentrate specific minerals. These processes can result in the loss of some nutrients and trace elements. In contrast, Seaweed Biofertiliser, such as SONIC Liquid Seaweed, is cold fermented, preserving the full spectrum of minerals and trace elements in a bio-available form.

No. SONIC Liquid Fish and Seaweed Biofertiliser products are 100% natural and non-toxic, with no withholding period. Safe for livestock, pets, humans, and the environment, they integrate easily into everyday farm routines. In fact, SONIC Liquid Seaweed also doubles as a Mineral Feed Supplement, supporting animal nutrition and performance.
SONIC Biofertiliser products have a mild, non-offensive odour—nothing like the strong odour of many emulsion fertilisers. This is because these products are naturally fermented using beneficial microbes, which help maintain balance during the processing, and preventing the liquid fish and seaweed from going rancid. When spraying, you may notice the scent initially, but it will dissipate quickly.
How to Reduce Farm Odours with Beneficial Microbes
We source leftover fish waste from numerous fish shops around Australia. These shops provide us with their ocean-caught fish after it has been processed for human consumption. Once the fish is collected, it is placed in large barrels or IBC containers. Once the fish is collected, it is placed in large barrels or IBC containers. Then the fish is cold processed (fermented) using microbial cultures, until the fish breaks down and becomes a rich liquid mineral concentrate that plants can easily absorb.
