On-Farm Biofertiliser Production Systems

Producing biological fish and seaweed fertilisers on-farm can significantly reduce input costs through:

Lower freight costs – Shipping dried raw ingredients instead of finished liquid products can substantially reduce freight costs. Actual savings depend on your location and order size.

Less packaging and waste – Reuse your fermentation and storage containers across batches, reducing the need for new packaging.

Lower ongoing production costs – Make your own liquid fish and seaweed biofertilisers and livestock supplements for an indicative $1.00–$1.20/L after initial setup and training. First-batch, including setup and training, costs approximately $1.80–$3.50/L, depending on system size and package requirements.

The starter package covers your raw ingredients including Australian organic dried seaweed, Australian dried ocean fish (discards from processing), proprietary Starter Cultures, and supporting materials.

Fermentation containers and equipment for decanting aren’t included in the Starter Package price because most farmers save money by buying them locally rather than paying to freight bulky items.

During your strategy call, we’ll talk through exactly what your system needs and can often point you to a supplier near you. If you’d rather not source it yourself, we can supply the equipment for you.

SONIC DIY Systems can be tailored to grazing properties, orchards, broadacre farms, market gardens and smaller mixed farms.

The system is sized around how much liquid fish and seaweed biofertiliser your farm uses and when you need it. Your production and application schedules are custom designed to suit your operation, so you can make the right batch quantities and have fresh product ready when you need it.

Allow approximately 2½ hours of hands-on labour per 1,000 L for batch preparation, decanting and clean-down. These are labour hours, rather than the elapsed fermentation time. Actual labour requirements vary with your setup and equipment.

SONIC Liquid Fish and Seaweed Biological Fertilisers feed both your plants and your soil, so you get short-term growth support and long-term gains in soil health.

Farmers typically use them to:

• Give plants fast-available nutrients
• Feed and stimulate beneficial soil microbes
• Improve nutrient cycling in the soil
• Strengthen root development and crop resilience
• Build soil structure and long-term fertility

Fish is rich in organic nitrogen and amino acids that drive growth. Seaweed adds trace elements and natural plant compounds that help crops handle stress. Used together, they can cover both what your plants need now and what your soil needs long-term.

It mainly comes down to how much liquid fish and seaweed you use and how hands-on you want to be.

Made-to-order is the better fit if you:

• Use smaller volumes, or are trying biofertiliser for the first time
• Want a finished product delivered, ready to dilute and apply
• Don’t have the time or space to run your own batches

Our liquid fish and seaweed is made-to-order, priced by volume – $2.30–3.90/L, with a 180L minimum per product.

Making your own is the better fit if you:

• Want the lowest cost per litre (from $1.00–1.20/L after your first batch training)
• Want to cut freight costs and rely less on outside supply
• Like the idea of producing fresh biological products on your own farm

Starter packages start from $1,885 for a 540L system, with 1:1 training and VIP support through your first three batches.

Yes. SONIC biofertilisers are 100% natural and can be added to most farming programs, whether you’re fully regenerative or just starting to cut back on synthetic inputs.

Works well with:

• Other natural inputs, such as compost, manures, biodynamic preparations and natural amendments
• Seed treatments, soil drenches and foliar sprays
• Regenerative management practices

Keep separate from:

• Synthetic fertilisers, urea and chemical-based products. Mixing them in the same tank reduces the benefit, because these products can harm the beneficial microbes in your biofertiliser.

Yes. We supply farms across most regions of Australia, from our base in Dorrigo, NSW and Central Coast, NSW.

Made-to-Order Biofertiliser:
Freight is quoted to your farm based on your location and order size. Because you’re shipping finished liquid, freight can be a big part of the total cost, especially for remote farms or large volumes.

DIY Biofertiliser Systems:
We ship dried raw ingredients rather than liquid, which is much lighter and cheaper to freight. Containers and pumps can usually be bought locally, and training can be done by live video, so wherever your farm is, you can get started.

Your quote will confirm freight costs and delivery timing for your area.
