The debate is often framed as an organic versus chemical fertiliser debate. But the better question is: are we only feeding the crop, or also building the soil that feeds it? #### **What Chemical Fertilisers Do Well** Chemical fertilisers deliver targeted nutrients quickly and predictably, helping growers address deficiencies and maintain production. They are not the problem. They are an essential tool in productive farming systems. But while fertilisers supply nutrients, they are not designed to rebuild soil structure, restore organic matter or increase biological activity. #### **The Missing Piece: Soil Health** Healthy soil does more than feed plants. It stores and cycles nutrients, supports biological activity, encourages root growth, holds moisture during dry periods, and allows water to move through the profile when conditions are wet. Across South East South Australia, Central Victoria and Western Victoria, many soils have supported generations of productive farming. Over time, intensive production can place pressure on how those soils function. Cultivation, grazing pressure, machinery traffic, and continuous crop removal can reduce organic matter, limit biological activity, weaken structure, and contribute to compaction. #### **What Organic Compost Brings to the System** Quality compost plays a different role. Rather than simply supplying nutrients, it helps improve the health and function of the soil itself. Compost can help: Its value is not just as a nutrient source, but in improving the environment where roots grow, and fertilisers operate. #### **How Compost Improves Fertiliser Efficiency** Compost and fertiliser are often assessed as competing choices. In practice, they can work together. Healthier soil can help reduce nutrient losses through leaching, run-off or poor retention. By improving structure, organic matter and biological activity, compost can help keep nutrients available in the root zone for longer. #### **What Is Your Program Trying to Achieve?** The right approach depends on the goal. Short-term crop response, long-term soil improvement, nutrient retention, water-use efficiency and dry-season resilience may all require different tools. Strong farming systems often invest in both nutrition and soil condition. #### **The Case for an Integrated Approach** The strongest approach is not organic or chemical. It is using each for what it does best. Fertiliser provides targeted nutrition when crops need it. Compost helps build organic matter, improve soil structure, support biological activity, and create conditions that enhance nutrient efficiency. This is not about replacing fertiliser. It is about building soils that help inputs work harder. #### **Where AgriGro Fits In** For growers wanting a practical compost-based soil amendment, Bio Gro’s [AgriGro range](https://content.biogro.com.au/agricultural-soil-amendments) offers options to suit different soil and production goals. The range starts with AgriGro, Bio Gro’s high-quality, certified 100% compost soil amendment, derived from natural organic material and designed for horticultural, broadacre and pasture-based systems. For more specific requirements, AgriGro formulations combine compost with organic nutrients and selected mineral elements, while AgriGro Custom can be tailored to individual soil constraints. Used as part of a broader soil and nutrition program, AgriGro can help build organic matter, support microbial activity, and improve the soil environment in which crops and fertilisers perform. #### **The Cost-Effectiveness of AgriGro** With imported fertiliser costs remaining exposed to global supply, freight, energy and currency pressures, many growers are looking more closely at the return on every fertiliser dollar. AgriGro supports that strategy by helping improve the soil conditions that allow nutrients to be retained, cycled and accessed by plants. In a healthier soil structure, fertiliser is more likely to stay where it is needed and work more efficiently. The cost-benefit is not measured in a single season. By building organic matter, structure, and biological activity over time, AgriGro can contribute to stronger soil function, greater resilience, and more sustainable long-term productivity. #### **What Role Is Soil Health Playing in Your Fertiliser Program?** If soil health is not playing a big enough role in your fertiliser program, it may be time to look beyond nutrient replacement. A stronger soil improvement strategy can help you get more value from fertiliser, improve resilience and support productivity over time. If you’d like to explore how compost could complement your fertiliser program, talk to the Bio Gro team. We can help you consider practical ways to improve soil health, support nutrient efficiency and build a stronger foundation for future production.
