Hanaminno Soil Carbon Project

Hanaminno Soil Carbon Project is a soil carbon sequestration project located on the 'Hanaminno' property near Boorowa, New South Wales, approximately 115km northwest of Canberra. Registered in March 2025, the project currently covers 2056.32 hectares, following a variation in August 2025 that removed specific areas from the initial project boundary.

Soil carbon projects operating under the 2021 Measurement and Models methodology aim to increase the amount of carbon stored within agricultural soils. This particular project achieves its sequestration goals by altering the stocking rate, duration, and intensity of grazing to promote soil vegetation cover and improve overall soil health. Additionally, the proponent applies non-synthetic and synthetic fertilizers to the land to address material nutrient deficiencies.

The project lies in the Hilltops local government area within the South West Slopes region of NSW, an area predominantly utilized for grazing and mixed agricultural farming. The local environment experiences a temperate climate with an average annual rainfall of approximately 608mm. Soils in the broader Boorowa catchment typically consist of yellow podzolic soils, earth types, and alluvial soils, which historically face regional degradation challenges such as dryland salinity and topsoil acidification.

Interestingly, the Hanaminno property is well-known in the regenerative agriculture space. It is managed by Margan Pastoral Company and Charlie Arnott, an award-winning eighth-generation biodynamic farmer, educator, and podcast host. Atlas Agri Solutions, a firm focused on combining grazing management with soil carbon tracking, is also a key proponent. Over the past two decades, Hanaminno has transitioned from a conventional, high-input farming model to holistic, chemical-free grazing practices that work in harmony with natural ecological systems.
