Messner Carbon Project 22

Messner Carbon Project 22 is a soil carbon project located in the eastern Wheatbelt region of Western Australia, approximately 40km southeast of the town of Mukinbudin. Registered on August 5, 2024, the project covers a land area of 387 hectares. The project is situated within an agricultural zone dominated by broadacre cropping (wheat, barley, canola) and sheep grazing, typical of the Shire of Mukinbudin and Shire of Westonia border region.

The project operates under the Estimation of Soil Organic Carbon Sequestration using Measurement and Models methodology (2021). This method requires the proponent to implement new management activities, in this case, applying synthetic or non-synthetic fertilizers to address nutrient deficiencies, to increase Soil Organic Carbon (SOC) stocks. These activities are designed to boost plant biomass and root growth, thereby sequestering more carbon in the soil profile compared to the baseline. The methodology requires rigorous physical soil sampling and modelling to generate Australian Carbon Credit Units (ACCUs).

Environmental conditions in this part of the Wheatbelt are semi-arid with a Mediterranean climate pattern. The area typically receives low annual rainfall, averaging between 300mm and 350mm, which is winter-dominant. The landscape is generally characterized by gently undulating plains with soils that vary from sandy loams and "light lands" on higher ground to heavier clays and duplex soils in the valley floors.

The project is managed by Agriprove Solutions, a major developer in the Australian soil carbon sector. The "Messner" project series (including Project 1, 23, and others) indicates a large-scale aggregation involving the Messner farming entity, likely spreading risk and logistical costs across multiple land parcels in the district.
