Weatherall Carbon Project 1

Weatherall Carbon Project 1 is a soil organic carbon sequestration project located approximately 20km north of Gundagai near the town of Coolac in New South Wales. It was registered in June 2026 and covers an area of 417.52 ha. The surrounding Riverina slopes region is well known for its agricultural land use, specifically beef cattle grazing, fine wool production, and mixed cropping such as wheat and mustard seed.

Projects operating under the Estimation of Soil Organic Carbon Sequestration using Measurement and Models methodology aim to build carbon stocks in agricultural soils. This is achieved by introducing new or materially different land management activities, and the carbon accrual is calculated through a combination of direct soil sampling and modelling. The standard requirements for these projects include baseline soil testing and ongoing measurements over the crediting period to prove additionality and verify accurate carbon storage.

The Gundagai and Coolac area generally experiences moderate rainfall, averaging roughly 624 mm annually. The soils in this region can vary from sandy loams to heavier clays, and are historically prone to acidity. To address these environmental constraints and build soil carbon, the Weatherall project involves applying lime and other ameliorants to remediate acid soils, as well as adding nutrients via synthetic or non-synthetic fertilisers to correct material deficiencies.

In addition to soil amendments, the project activities include altering the stocking rate, duration, and intensity of grazing to improve soil health and promote vegetation cover. It also involves establishing and permanently maintaining pasture on land that was previously cropland or bare fallow. Interestingly, the property name "Weatherall" has been associated with a long-standing local fine wool farming enterprise comprising 920 hectares, indicating this 417.52 ha project is actively integrating carbon farming into traditional, established agricultural operations. The project is guided by the proponent AgriProve, which is one of Australia's leading developers of technology-driven soil carbon projects.
