Sinclair Carbon Project 4

Sinclair Carbon Project 4 is a soil carbon sequestration project located in the Tatiara district of South Australia, approximately 15 kilometers north of Bordertown. Registered on July 16, 2024, the project covers a land area of 236.23 hectares. It is part of a larger aggregation of projects managed by Agriprove Solutions, which includes the neighbouring Sinclair Carbon Project 5 and Sinclair Carbon Project 6, suggesting a significant coordinated effort across the property or local landholding.

The project operates under the Carbon Credits (Carbon Farming Initiative-Estimation of Soil Organic Carbon Sequestration using Measurement and Models) Methodology Determination 2021. This methodology requires the proponent to baseline current soil carbon levels and implement new land management activities to sequester additional carbon over time. The specific activities for this project include applying synthetic or non-synthetic fertilisers to address nutrient deficiencies, switching from intensive to reduced or no-tillage practices, and retaining crop stubble. These practices are designed to minimize soil disturbance and increase organic matter input, thereby boosting soil health and carbon storage.

The Tatiara region is a highly productive agricultural zone known for mixed farming, primarily winter cropping (wheat, barley, canola) and livestock grazing. The area typically experiences a Mediterranean climate with an average annual rainfall of approximately 450-500mm. The local terrain generally features flat to gently undulating plains with soils that are often characterized as sandy loams over clay (duplex soils) or deep sands in some patches. These soil types are responsive to the improved management techniques proposed by the project, particularly stubble retention which helps protect the topsoil and retain moisture.
