Hanaminno Soil Carbon Project

Hanaminno Soil Carbon Project is a soil carbon sequestration project located at "Hanaminno," a historic property situated approximately 15km south-west of Boorowa in the Hilltops region of New South Wales. Registered in March 2025, the project covers 2,056 hectares and is situated within the South West Slopes, a region heavily utilised for mixed farming and grazing.

The project operates under the 2021 Soil Carbon (Measurement and Models) methodology, which credits increases in soil organic carbon (SOC). The standard requirements for this method involve establishing a baseline of SOC stocks through physical sampling, implementing new management activities, such as the application of nutrients (compost, lime, gypsum) and time-controlled grazing, and then re-sampling over time to measure sequestration. The project is managed by Atlas Agri Solutions in partnership with the landholder, Margan Pastoral Company.

The environment at Hanaminno features undulating hills with a mix of basalt and granite soils, which are critical determinants for carbon sequestration potential. The region typically experiences a temperate climate with an average annual rainfall of approximately 600mm. The property is owned by Charlie Arnott, a prominent figure in the Australian regenerative agriculture movement and recipient of the Bob Hawke Landcare Award. Hanaminno has transitioned from conventional high-input farming to biodynamic and holistic grazing principles over the last 15 years, using these methods to improve soil health and biodiversity.
