Biofertiliser Usage Estimator
Find the Right System for Your Farm
SONIC will use these estimates to recommend a suitable system and production schedule. Use the estimator to calculate;
✔ Liquid fish and seaweed quantities per full tank
✔ Area covered per tank
✔ Number of tank fills required
✔ Total product required for one application

On-Farm Biofertiliser Production FAQs
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.
