Calling All Aussie Farmers…

Have you noticed that your soil isn’t quite what it used to be?

It’s not that your farm isn’t working hard—it’s just that, over time, the land has been pushed to its limits.

The heavy reliance on conventional fertilisers and practices has taken a toll, and your soil’s health may not be what it once was.

When soil loses its vitality, it’s not just your crops that suffer; it’s your productivity, crop resilience, and your long-term farm health.

But here’s the good news: there is a way forward.

Imagine being able to nourish your soil naturally, restoring and improving its health and fertility over time.

Natural, ocean-derived Liquid Fish and Seaweed Biological Fertilisers work with your soil, not against it, improving its structure and boosting microbial activity—without relying on harsh chemicals.

We’re not offering a silver bullet that will instantly rejuvenate your soil, but we’re providing the tools and knowledge to help you begin the journey back to better soil, for the long term.

Are you ready to take the first step towards a healthier, more sustainable future for your farm?

We’re here to help you make that change, with practical solutions to improve your soil health, naturally.

Farmer Spotlight

Starting out in Australian orchard farming can be a challenge—especially when it comes to maintaining healthy soil and ensuring strong, productive trees. For Wayne and Sue Green, managing their 16-hectare pecan farm near Mudgee, NSW, meant facing these very hurdles.

In July 2023, they turned to SONIC Liquid Fish and Seaweed Biological Fertiliser, processed on their farm through their SONIC DIY Production System.  Wayne and Sue’s goal; to tackle soil health and boost tree growth.

We caught up with Wayne and Sue to hear about the exciting results they’re seeing—from healthier, “fat” sheep to noticeably improved soil health and thriving pecan trees. Want to see how their farm is going?  Watch the video to check out the impressive progress at Valley View Pecans →

Frequently Asked Questions

What specific benefits should I expect to see using liquid fish and seaweed biofertiliser?

These products work wonders on your soil, helping crops grow stronger, more resilient, and healthier. When used with regenerative farming practices, they support the soil’s microbial life, providing essential nutrients in their most bioavailable form, ensuring long-term, sustainable farming success.

What's the difference between liquid seaweed extract, such as 'Seasol', and liquid seaweed biological fertiliser?

Liquid seaweed extract is chemically or heat-extracted to concentrate specific nutrients like potassium for a quick boost. In contrast, biological seaweed fertiliser is naturally fermented, preserving a broader range of nutrients and adding beneficial microbes and enzymes that support soil health and plant growth. Seaweed ferment offers a more holistic solution, addressing both immediate and long-term fertility needs.  Read our article Liquid Seaweed Fertiliser Comparison:  Ferment Vs Extract

How long does it take to see results after applying fish and seaweed biofertiliser?

Results from biological fertilisers vary by crop, soil, and growing practices, but beneficial microbes and nutrients start working immediately to enrich the soil and support plant growth. Pasture improvements often show as fast germination and strong early growth, while orchard and vegetable growers typically see better growth, tastier produce, and longer shelf life.

Are SONIC Biofertiliser products environmentally friendly?

Yes, SONIC products are designed with the environment in mind. We use 100% Australian-sourced, natural ingredients like ethically harvested seaweed and fish waste that would otherwise go to landfill. By turning these resources into powerful biological fertilisers, we reduce waste and promote sustainability. Our products contain no synthetic additives—just fresh, potent solutions for maximum benefit. We produce our biofertilisers made-to-order, eliminating waste from mass production and storage. Additionally, our refill program allows farmers and growers to refill their containers, enabling the reuse of plastic packaging.

Is there a withholding period after applying biological fish and seaweed fertilisers?

No, there is no withholding period after applying our biological fish and seaweed fertilisers because they are 100% natural and non-toxic to livestock. In fact, our liquid seaweed is a mineral feed supplement, providing multiple health benefits for animals. These fertilisers are safe to use around children, livestock, and pets, allowing you to integrate them seamlessly into your farming practices without any concerns about safety or toxicity.

Do SONIC Biological Fertiliser products have a shelf life?

We advise following the recommended storage guidelines and usage window of 3-6 months from the batch date. This will allow you to take full advantage of the products’ peak biological performance and get the most value from your investment.

Use and Storage Information (download).

Do SONIC liquid fish and seaweed biofertilisers have a bad smell?

Our biological products have a mild, non-offensive smell—nothing like the strong odour of many fertilisers. This is because they’re naturally fermented with beneficial microbes, which help maintain a healthy balance during processing and prevent the product from going bad.  You might be interested in our article; How To Reduce Farm Odours With Beneficial Microbes.

How does SONIC Natural Farming differ from other fertiliser companies?

SONIC Natural Farming sets itself apart with three flagship products, made to order and delivered fresh to ensure maximum potency. Unlike bulk producers, we prioritise bioavailability by shipping directly to you within days of production. We offer farm-based biofertiliser production with our expert team, providing all materials and handling the process, or hands-on training to empower farmers to continue production independently, with ongoing support.
