Vale Carbon Project 4

Vale Carbon Project 4 is a soil carbon sequestration project located in the Woolumbool district, approximately 30 kilometers northwest of Naracoorte in South Australia’s Limestone Coast region. Registered in August 2024, the project covers roughly 104 hectares of agricultural land.

The region is a significant hub for livestock grazing and cropping, supported by a Mediterranean climate with reliable winter rainfall. The local landscape, part of the Woolumbool Land System, typically features undulating sandy plains and limestone ridges. The soils are often sandy loams over clay subsoils; these soil types can be prone to acidity and nutrient deficiencies, making them well-suited candidates for the remediation activities proposed in this project, such as lime application.

Managed by Agriprove Solutions, the project operates under the 2021 Soil Carbon methodology. This method credits landholders for measured increases in soil organic carbon (SOC) stocks over time. To achieve this, the project employs a combination of management changes, including applying lime to correct soil pH, using synthetic or non-synthetic fertilizers to address material deficiencies, re-seeding pastures to improve biomass, and altering grazing intensity to promote better ground cover and soil health.
