Guilfoyle Carbon Project 10

Guilfoyle Carbon Project 10 is a soil carbon sequestration project located approximately 15km northeast of Birchip in the Mallee region of Victoria. Registered on September 19, 2022, the project covers a project area of roughly 129 hectares. It is one of a series of "Guilfoyle" projects (such as Guilfoyle Carbon Project 7) situated in the Buloke Shire, suggesting a larger agricultural property has been stratified into distinct carbon estimation areas.

The project operates under the "Estimation of Soil Organic Carbon Sequestration using Measurement and Models" (2021) methodology. This framework allows landholders to earn Australian Carbon Credit Units (ACCUs) by increasing the amount of organic carbon stored in their soil. To achieve this, the project has implemented specific land management activities including the application of synthetic or non-synthetic fertilizers to correct nutrient deficiencies, the retention of crop stubble to protect soil structure, and a conversion to reduced or no-tillage farming practices. These activities are designed to minimize soil disturbance and maximize biomass retention, thereby sequestering atmospheric carbon into the ground.

The surrounding Mallee region is a major agricultural hub, primarily utilized for dryland cropping (wheat, barley, canola, and lentils) and livestock grazing. The environment is classified as semi-arid with an average annual rainfall of approximately 370mm. The local soil profiles are typically characterized as clay loams and calcareous earths, which can benefit significantly from improved organic matter retention to boost water-holding capacity.

The project is developed by Agriprove Solutions, a prominent soil carbon developer in Australia. Agriprove typically utilizes a "digital twin" model, combining physical soil sampling with satellite data and modelling to monitor soil health and carbon abatement over the 25-year permanence period.
