Harrison Carbon Project

The Harrison Carbon Project is a soil carbon sequestration project located in the locality of Pallamana, South Australia, approximately 15 kilometres northwest of Murray Bridge. Registered in August 2021, the project covers an area of roughly 199 hectares within the Murraylands region, an area traditionally utilized for mixed farming operations including cereal cropping and livestock grazing.

The project operates under the Carbon Credits (Carbon Farming Initiative, Measurement of Soil Carbon Sequestration in Agricultural Systems) Methodology Determination 2018. This methodology requires the proponent to empirically measure soil organic carbon levels before and after implementing new management activities. To generate Australian Carbon Credit Units (ACCUs), the project must demonstrate a measurable increase in soil carbon stocks over time.

The local environment in Pallamana is characterized by a semi-arid climate with an average annual rainfall of approximately 300-350mm. The terrain typically consists of gentle slopes and flats featuring sandy loam topsoils over red sandy clay subsoils. These sandy soils can be susceptible to wind erosion, making the project's specific activities, such as converting to reduced or no-tillage practices and retaining stubble, particularly beneficial for soil stability. The project also employs strategies to address nutrient deficiencies and alter grazing intensity, aiming to build soil resilience and carbon content in this moisture-limited landscape.
