Vielun Soil Carbon Project

Vielun Soil Carbon Project is a soil carbon sequestration project located at Mullamuddy in the Mid-Western Regional local government area, approximately 10 to 15km south-east of the major inland town of Mudgee in New South Wales. It was registered on May 25, 2026, and covers an area of 618.68 hectares.

The Mudgee region is renowned for its strong agricultural industry, with land use largely dedicated to cattle and sheep grazing, as well as cropping and viticulture. The area typically experiences moderate, temperate rainfall (averaging around 670mm annually), which supports reliable pasture growth. Soils across the Central Tablelands and slopes are predominantly Chromosols and Dermosols. These soils generally consist of loamy topsoils over clay subsoils, offering moderate agricultural potential that is highly suited to pasture and grazing systems.

This project is registered under the Carbon Credits (Carbon Farming Initiative, Estimation of Soil Organic Carbon Sequestration using Measurement and Models) Methodology Determination 2021. Soil carbon projects involve undertaking new or materially different land management activities to increase the amount of carbon stored in the soil. Standard requirements for this methodology include establishing a baseline carbon level through rigorous soil sampling, and subsequently estimating increases every 1 to 5 years via laboratory measurements or calibrated in-field sensors, while accounting for any project-related emissions like livestock or fertiliser use.

To actively increase soil carbon stocks, the Vielun Soil Carbon Project focuses on altering the stocking rate, duration, and intensity of grazing. These activities are designed to promote greater soil vegetation cover and improve overall soil health within the agricultural system. Notably, the project is situated on the Vielun Pastoral Company property, a prominent Poll Hereford stud operated by proponent Sam Broinowski. This project highlights how regenerative grazing practices designed to capture carbon can be successfully integrated into premier livestock breeding operations.
