Welcome to Draught Horse Bio Fertilisers
Bringing biology back into WA's soil — NATURALLY
How it works
At Draught Horse Bio Fertilisers, we believe healthy soil is the foundation of productive farming. That’s why we’ve dedicated over 40 years to developing natural, batch-fermented biological fertilisers that work with your soil’s biology — not against it.
Our products, including Fish and Kelp Hydrolysates, worm castings and beneficial bacilli, are designed to help farmers break free from the costly cycle of chemical inputs like urea, MAP, DAP and lime. By feeding the soil instead of just the crop, you can reduce input costs, improve soil structure and grow healthier, more resilient crops and pastures.
How Does the Product Work?
Natural, biological fertilisers that support your soil — not fight it.Our biological fertilisers are made through a careful fermentation process that extracts amino acids and nutrients from ocean and plant sources. These ingredients act as a natural stimulant for soil biology, encouraging the growth of beneficial fungi and bacteria.
This microbial activity improves soil structure, breaks down crusty layers and enhances nutrient cycling. The result is healthier soil that retains moisture better, supports larger root systems and produces stronger, more resilient crops and pastures.
How Our Biological Fertilisers Work — A Natural 4-Step System
- Fermentation of natural inputs – fish, kelp and plant matter are batch-fermented with beneficial microbes to create nutrient-rich inputs full of amino acids and minerals.
- Activation of soil biology – once applied, our fertilisers stimulate a surge in microbial activity, including the growth of mycelium, the root-like structure of fungi that forms networks transporting nutrients and water.
- Enhanced root and soil development – microbial activity breaks down compacted soil, increases organic matter and improves water retention, leading to deeper, stronger root systems.
- Long-term soil regeneration – improved soil biology and structure reduce reliance on expensive chemical inputs, supporting a more resilient, profitable farming system.

- Foliar spray
We also provide education, testimonials and real-world examples to help farmers understand how biological inputs can transform their land.
The Science
With over 40 years of experience in fermenting and extracting plant and fish amino acids, we’ve developed a proven method for creating high-quality, plant-available nutrients. Our products combine micro and macro nutrients in a way that supports rapid soil aggregation.
This aggregation is driven by increased fungal and bacterial activity, which helps build soil structure and organic matter. Larger root masses develop, increasing soil carbon and humus — key indicators of long-term soil health and productivity.
The Benefits
- Larger root mass – supports better nutrient uptake and increases soil carbon and humus.
- Improved soil structure – enhances water retention and aeration.
- Reduced chemical dependency – cuts costs and supports sustainable farming.
- Healthier crops and pastures – more resilient to stress and better performing in poor soils.
- Long-term soil regeneration – invest in the future of your land with natural inputs.
Compost & Inoculum Gallery
Mycelium development in compost and brewed biology.Why Compost Biology Matters
These images show mycelium and fungal activity in compost and cultured inoculum. Healthy fungal networks help break down organic material, release nutrients and build stable aggregates that carry through into the paddock.
By feeding soil biology with natural inputs, Draught Horse Bio Fertilisers supports the growth of these networks — building healthier, more resilient soils across Western Australia.
Field Mycelium Gallery

Here we see mycelium running through straw bales and surface residues in the field. This is where compost biology meets the farm system, helping to recycle stubble, protect soil and create pathways for water and roots.
When biological fertilisers are used consistently, these fungal networks extend out across the paddock, supporting soil structure and nutrient cycling season after season.

Fungal–Root Partnerships
These images focus on mycelium directly attached to plant roots. This is where nutrient and water exchange takes place, supporting crop resilience and long-term soil regeneration.
Building and maintaining these partnerships is a core aim of the Draught Horse Bio Fertilisers approach — feeding the biology that feeds the crop.
