Rising fertiliser costs and supply uncertainty are no longer theoretical risks for Australian growers; they are active pressures on production planning. In early 2026, escalating conflict in the Middle East has disrupted shipping through the Strait of Hormuz, a key route for globally traded fertilisers. When supply chains tighten, prices rise, and availability becomes unpredictable, particularly in import-dependent markets like Australia.
With Australia importing approximately 85% of its fertiliser requirements, growers are increasingly exposed to global volatility beyond their control. For high-value vegetable systems, where timing and consistency are critical, this creates a “perfect storm”:
At the same time, agronomic research continues to highlight the benefits of improving soil health, particularly in terms of organic carbon, structure, and nutrient efficiency. This creates a practical opportunity: not to replace fertiliser, but to use it more effectively within a broader soil management system.
Traditionally, resilience in field vegetable systems has focused on irrigation, pest and disease control, and yield stability. Today, resilience must also include:
For growers across regions such as the Goulburn Valley, Central Victoria and South East South Australia, this shift is particularly relevant. Soil constraints, ranging from sandy, low-organic-carbon profiles to compacted heavier soils, already challenge nutrient management.
A resilient system should aim to:
In many intensive vegetable systems, fertilisers are applied to meet immediate crop demand. However, without sufficient soil structure and organic matter, efficiency is often limited.
Common challenges include:
This creates a dependency cycle in which higher inputs are required each season to maintain yields.
A better approach is to improve how nutrients are retained and used within the soil system.
Compost-based amendments, such as Bio Gro’s AgriGro range, provide a practical mechanism to improve soil performance alongside fertiliser programs.
Agronomically, these products can:
Applied in vegetable systems:
Maintaining yield and crop quality remains non-negotiable. For this reason, compost-based amendments should be integrated with conventional fertiliser strategies rather than replacing them outright.
A balanced approach includes:
This delivers:
Vegetable production is highly sensitive to input costs. Even modest efficiency gains can significantly impact profitability, especially when fertiliser prices are elevated.
Integrating compost-based amendments can:
In the current environment, these efficiencies translate directly into risk mitigation.
Across key vegetable-growing regions in Victoria and South Australia, soil challenges vary but share a common theme: nutrient holding and structure drive productivity.
Sandy soils:
Heavier soils:
Crop requirements further reinforce the need for balanced soil management:
In each case, improving soil structure and nutrient efficiency is critical to both yield and quality.
Bio Gro supports growers with locally produced compost-based soil amendments through the AgriGro range. Products include 100% compost and blended formulations with manures and mineral inputs, allowing solutions to be tailored to crop and soil conditions.
Key advantages include:
In a time of global uncertainty, access to consistent, locally available inputs is a strategic advantage.

A staged approach helps minimise risk and maximise outcomes:
The future of fertiliser use is about using it better.
For growers across South Eastern Australia, the opportunity is clear:
Periods of disruption often drive innovation. For many growers, this is the right time to rethink soil nutrition and build more resilient farming systems.
