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

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.

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.

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.

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.

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.
