You’ve seen the price hikes. You’re paying more for freight. And half the time, you’re waiting on supply that may or may not turn up when you need it.
If you’re relying on bought-in organic fertilisers you’re at the mercy of that system.
With a SONIC On-Farm Biofertiliser Production System, you’re back in control. You can make your own organic fertilisers—fresh, effective, and ready when you are.
A DIY System makes sense if you want to:
- Cut input and transport costs
- Stop relying on unpredictable supply chains
- Produce your own ‘living’ biological fertilisers
- Build healthier, more resilient soil season after season
For farmers moving toward self-sufficient biological farming, the SONIC On-Farm Biofertiliser Production System offers a practical way to keep your operation moving, regardless of what’s happening outside the gate.
Take Control and Save Big On Organic Fertiliser
Skip the expense of shipping commercial fertilisers with a SONIC On-Farm Biofertiliser Production System.

On-Farm Biofertiliser Production FAQ's
Producing biological fish and seaweed fertilisers on-farm can significantly reduce input costs, with farmers able to produce biological fertilisers (post-training), for around $1.20 per litre using a SONIC DIY System.
Savings also come from:
• Minimal freight costs
• Reduced plastic packaging costs and waste – by reusing on-farm storage
• Less reliance on expensive commercial inputs

We provide full support to help you set up and run your own on-farm biofertiliser system, including installation assistance and all inputs needed for processing Liquid Fish and Seaweed Biofertiliser, as well as Liquid Kelp Probiotic Livestock Supplement.
Training is delivered in person or via live video, guiding you one-on-one through the start of your first batch, with phone and email follow-ups during fermentation and before decanting. We support you through your first three batches with step-by-step guidance and a 100% quality guarantee.
Read about SONIC Biofertiliser Production and Training packages
We began in 2011 on our own farm, trialling low-cost biological approaches to improve soil health and reduce synthetic inputs. Drawing on regenerative systems, including biodynamic practices and Korean Natural Farming, we developed practical fermentation techniques and biological solutions suited to Australian conditions.
We’ve since worked alongside farms across a range of Australian regions, consistently observing improvements in soil biology, nutrient availability, and overall crop performance when fish and seaweed biofertilisers are integrated with regenerative practices.
After the initial setup and start-batch training session, we’ll check in midway through the batch and at the end of your first three (3) batches to ensure your production processes run efficiently.
Support includes:
- Photo based progress checks
- Phone and email support
- Supply of raw ingredients
- First three (3) batches are quality guaranteed
- Updates on product development

Yes, SONIC Systems are customised to meet the specific needs of your farm, with system sizes tailored to align with your specific spray regime and on-going liquid fish and seaweed biofertiliser requirements.
We’ve streamlined the process to be simple, streamlined, and repeatable by providing pre-measured ingredients and straight forward procedures. It essentially takes around 1 hour to start a 1,000L batch, then after fermentation is complete (10-12 weeks), it takes another 1–1.5 hours to decant and clean down. That’s roughly 2 hours total labour per 1,000L—often less time than organising orders, freight, and handling delivered products.
