Prosper Carbon Project

Prosper Carbon Project is a soil carbon project located in the Wimmera region of western Victoria, approximately 50km southeast of the major rural city of Horsham. Registered in December 2017, the project spans an area of 115.65 hectares. The broader Wimmera region is highly regarded for its agricultural output, primarily supporting broadacre grain cropping (such as wheat and barley) and sheep grazing. The area generally experiences a temperate climate with moderate winter rainfall averaging 400 to 500mm annually. The local landscape is defined by variable soil profiles, prominently featuring heavy cracking clays (Vertosols) and texture-contrast duplex soils (Sodosols).

Soil carbon projects operating under the Estimation of Soil Organic Carbon Sequestration using Measurement and Models 2021 methodology aim to increase the amount of carbon stored in agricultural soils by altering land management practices. This specific project achieves this by applying synthetic or non-synthetic nutrients to the land to address material soil deficiencies, and by re-establishing or rejuvenating pastures through seeding or pasture cropping. The resulting changes in soil organic carbon are calculated using a measurement-only approach, which involves direct soil sampling and laboratory analysis to estimate and verify sequestration.

Interestingly, this project underwent significant administrative updates in late 2025. In September 2025, the project proponent was officially varied from Corporate Carbon Solutions Pty Ltd to AGRIPROVE SOLUTIONS PTY LTD, with Agriprove Pty Ltd acting as the agent. Subsequently, in October 2025, the project transitioned from the older 2014 Sequestering Carbon in Soils in Grazing Systems method to the updated 2021 Measurement and Models determination. Public registry details also show that the project is operating with a 25-year permanence period running from May 2026 to May 2051.
