Vielun Soil Carbon Project

Vielun Soil Carbon Project is a soil carbon project located at "Mullamuddy Park", a pastoral property in Mullamuddy roughly 10 to 15 kilometres south of Mudgee in the Central West region of New South Wales. Registered in May 2026, the project covers an unspecified area but is situated in a district heavily utilised for agricultural purposes, particularly sheep and beef cattle grazing, mixed winter cropping, and viticulture.

Soil carbon projects operating under the 2021 methodology involve implementing new or materially different management activities to increase the amount of carbon stored in agricultural soils. For this specific project, the proponents are altering the stocking rate, duration, and intensity of their grazing. These changes are designed to promote soil vegetation cover and improve overall soil health, with the resulting carbon gains calculated through rigorous baseline soil sampling and subsequent modelling.

The Mudgee region typically experiences a temperate, semi-arid climate with moderate, winter-dominant rainfall. The area's environment is heavily characterised by Red Chromosols, commonly known as red-brown earths or duplex soils, which feature loamy topsoils over structured clay subsoils. These soils are often referred to as the workhorse of agriculture in New South Wales and are highly suitable for dryland farming and pasture growth.

An interesting note about this project is the collaboration between the proponents. The project is situated at Vielun Pastoral Company, a prominent Poll Hereford stud run by Sam Broinowski. The stud made headlines in 2021 when a syndicate it was part of broke the Australian Hereford price record by purchasing a bull for $160,000. Co-proponent Atlas Agri Solutions Pty Ltd is a company known for providing digital grazing management tools, such as the MaiaGrazing software app. This partnership suggests the carbon project will heavily leverage advanced livestock tracking, digital property mapping, and data analytics to optimise rotational grazing and maximise soil carbon yields.
