Greenhill SOC Project

Greenhill SOC Project is a soil carbon sequestration project located approximately 30km west of Maryborough in the Wide Bay-Burnett region of Queensland. Registered in December 2022, the project covers a project area of roughly 41 hectares. The site is situated within the locality of the Fraser Coast Regional Council, an area traditionally supported by cattle grazing, sugar cane, and forestry operations.

The project operates under the Estimation of Soil Organic Carbon Sequestration using Measurement and Models (2021) methodology. This method credits landholders for increasing Soil Organic Carbon (SOC) stocks through changes in land management. Standard requirements involve establishing a baseline of soil carbon through physical sampling, implementing new management activities, such as altering stocking rates, applying lime or fertilizer to correct deficiencies, and rejuvenating pastures with legumes, and then re-measuring or modelling carbon stocks over a 25-year permanent period to calculate the increase.

Environmentally, the region experiences a subtropical climate with significant rainfall, generally favorable for building soil carbon. The soil landscape in this district, often associated with the "Biggenden Beds" or nearby volcanic formations, typically features Ferrosols (red clay soils) and Dermosols. These soil types are generally well-structured and responsive to the pasture rejuvenation and nutrient management activities proposed by the project.

A notable aspect of this project is its proponent history; initially registered under GPC (QLD) Pty Ltd (trustee for Greenhill Pastures Trust), the participant name was varied to Agriprove Solutions Co No.2 Pty Ltd in May 2024. This suggests the project is managed by Agriprove, a leading developer in the sector known for utilizing pasture cropping and digital soil models. The Greenhill property also appears to host a separate "Avoided Clearing" project (Greenhill AC Project), indicating a multi-layered approach to carbon farming on the same aggregation.
