What is compost?

Compost is the natural process of recycling organic materials, such as grass clippings, wood chips, and pine needles, into a valuable fertiliser used to enrich soil and improve plant health. Composting speeds up the decomposition process of the organic matter, as it provides an ideal environment for bacteria, fungi, and other organisms doing all the work. The result is nutrient-rich, dirt-like material called compost!

What are the benefits of compost?

Compost is essential for improving soil health and contains three primary nutrients required by plants and crops – nitrogen, phosphorous, and potassium. There will also be trace elements of calcium, magnesium, iron, and zinc present in a good quality compost. Instead of relying on synthetic fertilisers containing harmful chemicals, compost offers an organic alternative, improving soil’s water retention properties, productivity, and resiliency and effectively suppressing weed seeds.


Compost also conserves water. Irrigation in agriculture is a major consumer of water in Australia and is very expensive and time-consuming for farmers to run and manage. The water retention properties of soil increases considerably with the addition of organic matter. For every 1% increase in organic matter per acre, the soil will hold approximately 75,000L more water. It’s easy to understand why farmers and growers alike are opting to use organic methods of fertilising to produce higher yields while conserving water.

Can I put compost on top of mulch?

Yes, you can put compost on top of mulch, and doing so can be beneficial for your garden soil and for large-scale applications. When adding compost over natural mulch, wood mulch or bark mulch, you’re improving the nutrient availability at the soil surface. It’s best to apply a thin layer of fresh compost directly on top of the existing mulch, which will help to slowly integrate the rich organic material into the soil as the compost breaks down, improving the overall soil organic matter content. However, be cautious not to layer the compost too thickly, as this can lead to excessive moisture retention and potentially suffocate the soil.

What is the difference between organic and synthetic fertilisers

  • Synthetic Fertilisers

    Composition: Made from chemicals and synthesized nutrients like nitrogen, phosphorus, and potassium.


    Source: Industrially produced using various chemical processes.


    Impact on Soil: Provides immediate nutrient availability, but can lead to soil degradation and reduced microbial activity over time.


    Environmental Impact: Can cause pollution through runoff, leading to issues like algal blooms in water bodies.

  • Organic Fertilisers

    Composition: Made from natural materials like compost, manure, bone meal, and plant residues.


    Source:  Derived from animal or plant waste and naturally occurring minerals.


    Impact on Soil: Improves soil structure, promotes microbial activity, and enhances long-term soil fertility.


    Environmental Impact: More sustainable, with lower risk of pollution and environmental harm.
