Reynolds Carbon Project 5

Reynolds Carbon Project 5 is a soil carbon sequestration project located in the Shire of Dowerin, approximately 25km south of the town of Dowerin in the Western Australian Wheatbelt. Registered in November 2023, the project covers 113 hectares of agricultural land. The region is characterized by broadacre cropping and sheep grazing, typical of the central Wheatbelt's agricultural landscape.

The project operates under the 2021 Soil Carbon methodology (Estimation of Soil Organic Carbon Sequestration using Measurement and Models). This method credits landholders for increasing soil organic carbon (SOC) stocks through changes in land management. Unlike tree planting projects, soil carbon projects allow for continued agricultural production. The specific activity nominated for this project is the application of synthetic or non-synthetic fertilizers to address material nutrient deficiencies, a practice designed to boost plant growth and, subsequently, the carbon stored in the soil profile.

Environmentally, the site sits within a semi-arid, Mediterranean climate zone, receiving relatively low annual rainfall of approximately 300-350mm. The soils in this part of the Avon River basin are typically a mix of sandy loams, gravelly sands, and duplex soils (sand over clay), which can be responsive to nutrient management but often face constraints like acidity or low organic matter.

This project is developed by Agriprove, a prominent soil carbon project developer in Australia known for its "monitor, manage, measure" approach. The designation "Project 5" suggests this is part of an aggregated estate or a split registration for a single landholding family, a common strategy to manage baselining and crediting periods across different paddocks or properties.
