Edenbridge Carbon Soil Project

Edenbridge Carbon Soil Project is a soil carbon sequestration project located near the locality of Leadville, approximately 20km southeast of Dunedoo and 50km north of Mudgee in the Central West region of New South Wales. Registered in August 2025, the project covers a project area of roughly 1,066 hectares.

This project operates under the 2021 Soil Carbon "Measurement and Models" methodology. This method credits landholders for increases in soil organic carbon (SOC) stocks achieved through changes in land management. Unlike tree planting projects, soil carbon projects focus on the ground below; activities typically include altering stocking rates, pasture rejuvenation, or, as in this case, the application of nutrients and ameliorants. Specifically, this project aims to remediate acid soils using lime and address nutrient deficiencies with fertilizers to boost plant growth and, consequently, soil carbon inputs.

The Dunedoo and Leadville region is traditionally characterized by mixed farming, including sheep and cattle grazing as well as cereal cropping (wheat, barley, canola). The area falls within a warm temperate climate zone with an average annual rainfall of approximately 600mm-650mm. Soils in this region can vary from sandy loams on slopes to heavier clays in the valleys, with soil acidity being a known constraint that this project actively seeks to manage.

An interesting aspect of this project is its specific focus on chemical amelioration (lime and fertilizer) as a primary lever for carbon sequestration. By correcting soil acidity and nutrient levels, the project aims to unlock higher biomass production in pasture or crops, which increases the organic matter returning to the soil system. The project is supported by climate consultancy firm Climate Friendly Pty Ltd.
