Cooeeanna Carbon Project 7

Cooeeanna Carbon Project 7 is a soil carbon sequestration project located on the Eyre Peninsula in South Australia, approximately 12 kilometers south of the town of Lock. Registered on September 12, 2025, the project covers 204.55 hectares of agricultural land within the District Council of Elliston area. The region is predominantly utilized for mixed dryland farming, characterized by a rotation of cereal cropping (such as wheat and barley) and sheep grazing.

The project operates under the Estimation of Soil Organic Carbon Sequestration using Measurement and Models Methodology Determination 2021. This high-integrity methodology allows proponents to earn Australian Carbon Credit Units (ACCUs) by measuring increases in soil carbon stocks over time, often using a hybrid approach of physical soil core sampling and digital modelling. The specific activity undertaken for this project involves applying synthetic or non-synthetic fertilisers to address material soil deficiencies. By correcting these nutrient imbalances, the project aims to boost plant growth and root biomass, thereby increasing the rate at which carbon is drawn from the atmosphere and stored in the soil.

Environmentally, the Lock district is situated in a semi-arid zone with an average annual rainfall of approximately 350mm to 400mm, receiving the majority of its precipitation in winter. The local landscape typically features calcareous sandy loams and red duplex soils, which can be prone to constraints such as low fertility or water repellence without careful management. As part of a broader engagement by proponent Agriprove Solutions, this project, alongside the neighbouring Cooeeanna Carbon Project 6, demonstrates a targeted effort to improve soil health and productivity in a region traditionally challenged by sandy, nutrient-poor soil profiles.
