Lyne Carbon Project

Lyne Carbon Project is a soil carbon sequestration project located in the Goondiwindi region of Queensland, approximately 30km northeast of Inglewood and west of Karara. Registered in May 2020, the project currently covers a Carbon Estimation Area of approximately 210 hectares within a larger agricultural property. The project is managed by Agriprove Solutions in partnership with landholders Peter and Angus Ramsey.

The project operates under the 2021 Soil Carbon "Measurement and Models" methodology, having transitioned from the 2018 method in early 2024. This methodology rewards landholders for increasing Soil Organic Carbon (SOC) stocks through improved management practices. Unlike the pure measurement method, this approach utilizes a hybrid of physical soil sampling and predictive modelling to estimate carbon sequestration, often reducing the cost and variance associated with generating credits.

Situated in the Southern Downs, the region is characterized by a mix of grazing and cropping operations. The area typically receives an annual rainfall of approximately 600-700mm, classified as a semi-arid to sub-tropical climate. The local soil landscape often features "traprock" soils, typically texture-contrast soils (Chromosols) or loams that can benefit significantly from increased organic matter to improve water holding capacity. The project activities include converting from set stocking to high-intensity rotational grazing across 16 paddocks, installing exclusion fencing to manage pest pressure (wild dogs and kangaroos), and rejuvenating pastures with diverse multi-species seeding including linseed, chicory, and clover.

Notable achievements for the Lyne Carbon Project include the issuance of over 1,100 Australian Carbon Credit Units (ACCUs), validating the sequestration gains. Reports indicate that the change in management practices has allowed the property to triple its effective stocking rate while simultaneously improving ground cover and soil health. In April 2025, a variation to the project area was processed to remove certain areas from the project boundary, refining the active carbon estimation zone.
