Hanaminno Soil Carbon Project

Hanaminno Soil Carbon Project is a soil carbon project located at the 'Hanaminno' property near Boorowa, in the Hilltops local government area of southern New South Wales. It was registered in March 2025 and covers an area of 2056.32 ha.

Soil carbon projects involve storing carbon in agricultural soils by adopting new or modified land management practices. Under the 2021 Measurement and Models methodology, standard requirements involve implementing eligible activities, such as altering the stocking rate, duration, or intensity of grazing to promote vegetation cover, and tracking soil organic carbon changes through rigorous physical measurements (soil coring) or models over the project's permanence period. This project also involves applying synthetic or non-synthetic fertilisers to the land to address material soil deficiencies.

The Boorowa region is characterized by a temperate climate with moderate rainfall, while the landscape of the Hanaminno property specifically features undulating basalt and granite hills. The region's predominant land use revolves around agriculture, notably mixed farming and the grazing of sheep and cattle.

The property is owned and operated by Charlie and Angelica Arnott via Margan Pastoral Company. Charlie Arnott is a prominent regenerative farmer and notably the first in five generations of his family not to work in the iconic Arnott's Biscuits family business. Approximately 15 years ago, Hanaminno transitioned from conventional high-input farming to organic, holistic, and biodynamic grazing principles. Today, the property focuses on producing pasture-raised Shorthorn cattle, sheep, and pigs. The carbon project is co-managed by Atlas Agri Solutions (Atlas Carbon), which recently partnered with the property to host field days aimed at educating other producers on treating soil carbon sequestration as a natural byproduct of diligent grazing management. Additionally, a variation to the project was recorded in August 2025, which removed specific areas from the project footprint.
