On Sunday, 19 October, we held a hands-on Composting Workshop at The Natural Circle Farm in Jarrahdale to demonstrate a range of effective compost-making techniques. The event was a collaboration between the Peel-Harvey Catchment Council (PHCC) and the Serpentine Jarrahdale Food and Farm Alliance, supported by funding from the State NRM through our Resilient Farms, Nature and Communities Project.

Participants learned how to build both anaerobic and aerobic composting systems:

The Johnson–Su anaerobic compost system, which decomposes organic material without oxygen. This slower, low-maintenance method produces high-quality compost over approximately 12 months, which will be used in the market garden at The Natural Circle Farm.

An aerobic static aeration compost system, powered by a solar setup assembled from off-the-shelf 4WD components and second-hand solar panels for around $1,000. The system can be scaled to suit different property sizes and compost volumes. It’s already reaching 40°C, with an ideal composting range of 55–60°C, and is expected to produce finished compost within 8–12 weeks.

 The compost workshop followed a very permaculture-based approach, being hands on and practical as well as using locally available materials such as old hay, silage, cow manure, and repurposed items. It emphasized creativity, resourcefulness, and working with what was on hand.

The day combined hands on, scientific information mixed with banter, lively discussion and shared learning – all while dodging the showers. With delicious food, vibrant farm setting with the Maremma companion dogs for the Pasture Egg laying Chooks providing vocal accompaniment to our endeavours made for memorable and successful workshop.
