Humphreys Carbon Project 2

Humphreys Carbon Project 2 is a soil carbon project located in the Shire of Wongan-Ballidu in the Western Australian Wheatbelt. The project area covers approximately 331 hectares and sits roughly 5km east of the small town of Cadoux and 50km northeast of the regional centre, Wongan Hills. Registered in June 2025, the project operates on land traditionally used for broadacre cropping and sheep grazing, industries that dominate this part of the state.

The project operates under the Estimation of Soil Organic Carbon Sequestration using Measurement and Models (2021) methodology. This method allows landholders to earn Australian Carbon Credit Units (ACCUs) by adopting new management activities that store carbon in the soil. For this specific project, the primary activity involves applying synthetic or non-synthetic fertilizers to address material nutrient deficiencies. By correcting these deficits, the project aims to boost plant growth and root biomass, which in turn increases soil organic carbon levels. As a "Measurement and Models" project, it likely utilizes a hybrid approach of physical soil sampling and digital modelling to quantify carbon abatement over time.

The Wongan-Ballidu region is characterized by a semi-arid Mediterranean climate with hot, dry summers and cool, wet winters. Annual rainfall averages around 360mm, which presents a challenging but viable environment for dryland agriculture. The local soils are typically a mosaic of sandy loams and clays, often requiring careful management to maintain productivity and structure.

This project is developed by Agriprove, a major Australian soil carbon developer known for its "digital twin" approach to soil monitoring. The project name and ID sequence (ERF185628) suggest it is part of a larger aggregation or series of projects (e.g., Humphreys Carbon Project 4 appears in later registry sequences), indicating a coordinated effort by the landholder to sequester carbon across multiple land parcels.
