Our Products

Charton & Bang are proud to make the CarbonRich line of soil health products.  We currently have CarbonRich Compost and CarbonRich Liquid Humus available for sale.  You can find more details about them at carbonrich.com.au

At our facility near Leeton in NSW, we process agricultural by-products to produce very high quality compost for use back into agriculture. We’re aiming for very low contaminant levels, and very high levels of the types of complex carbon molecules that help soils function at their best.

We have two product lines of high quality compost. One is made using straw and cotton gin trash, and the other using straw and chicken manure.

Our composting process transforms the raw ingredients into rich, earthy smelling compost. The composting process removes weed seeds and pathogens creating a safe product for your soil.

Our Liquid Humus product is a liquid extract from our compost. We concentrate the water soluble carbon from the compost to provide a product that can be applied to crops through drip irrigation or boom spray. This greatly increases the efficiency of compost application, and allows rates as low as 10L per hectare in broadacre agriculture and 20L/ha in horticulture.

Liquid Humus is most effectively used either through direct injection into the seed furrow when planting, or when mixed with liquid applications of fertiliser, particularly nitrogen. This provides a complex carbon source that can remove the burning effect of nitrogen, and increase the efficiency of nitrogen application by reducing losses to the atmosphere or being washed through the soil profile.

Our Liquid Humus product retails for $1100 per 1000 litre bulk container. This price includes a $100 charge for supply in 1000 litre bulk containers. This charge is waived if you provide the containers.

We sell our CarbonRich compost by the cubic metre in minimum loads of 10 cubic metres. You can pick up yourself or we can arrange delivery. Smaller loads only by special arrangement.

Our cotton based product start at $100 per cubic metre.

Our chicken manure based product excludes GMOs and starts at $125 cubic metre.

We can provide agronomic advice on amounts to use, and when and how to apply.

About Us

Charton & Bang founders after receiving council approval to construct their compost facility.

Charton & Bang produce high quality compost at Murrami in the Riverina, NSW on a farm that has been in the family for 100 years in 2021. Their focus is on using agricultural wastes to make products that help create farming systems that are more resilient, more profitable and easier to manage.

Charton & Bang were founded by three people: John Barton, Virginia Barton and Matt Chang.

John Barton is from the 4th generation of a farming family based immediately across the road from this facility. He has worked on a wide range of farm types in labouring, managerial and research roles. After retraining in science as an adult, John has spent the last 13 years working on the meeting point between science and the hard practicalities of large-scale commercial compost operations. John has had a hand in the production of 1 million cubic metres of compost in this time (around 1 million ute loads), and has helped design, commission and support 7 new commercial scale compost facilities around Australia.

Virginia Barton is from the 3rd generation of the same farming family as John. She was born and raised on the property across the road. Virginia handles client liaison and project management for Charton & Bang. After studying at the University of New England she has spent the last 20 years in Legal Publishing in various editorial and management roles for Thomson Reuters, rising to Head of Analytical Law for Asia Pacific.

Matt Chang is of Malaysian origin, where he was instrumental in growing the operations of the family swiftlet farming operation, producing nests for bird’s nest soup. Matt is now based in Australia and handles accounting and logistics for Charton & Bang.
