Products Made Fresh For Your Farm
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 fertilisers you’re at the mercy of that system.
With an On-Farm Biofertiliser Production System, you’re back in control. You can make your own liquid fish and seaweed biofertilisers—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

The Starter Package comes with 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.

After the initial setup and start-batch training session, you’ll receive scheduled VIP support throughout your first three (3) batches — typically over 9–12 months — allowing time to learn the nuances and natural variability of biological fermentation systems.
Support includes midway and end-of-batch check-ins, photo-based progress reviews, and phone/email assistance to help ensure consistent production quality.
After your first three batches, we continue to provide ongoing technical support and system management assistance for all active SONIC DIY Systems.
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 straight forward and repeatable by providing pre-measured ingredients and practical procedures. It approximately takes around 1 hour to start a 1,000L batch, then after fermentation is complete, it takes another 1–1.5 hours to decant and clean down. That’s roughly 2-2 1/2 hours total labour time per 1,000L—often less time than organising orders, freight, and handling delivered products.
