Pannell Carbon Project 11

Pannell Carbon Project 11 is a soil carbon sequestration project located in the Murray Mallee region of South Australia, approximately 40km southeast of the major town of Loxton. Registered in May 2025, the project covers a project area of nearly 350 hectares. The surrounding region is heavily utilized for dryland agriculture, specifically cereal cropping (wheat, barley) and sheep grazing, typical of the broader Riverland and Mallee districts.

The project operates under the Estimation of Soil Organic Carbon Sequestration using Measurement and Models Methodology Determination 2021. This methodology requires landholders to switch to new management activities that increase carbon storage in the soil. Specifically, this project activity involves applying synthetic or non-synthetic fertilizers to the land to correct material nutrient deficiencies. By addressing these deficiencies (often phosphorus or trace elements in this region), the project aims to stimulate greater plant biomass and root growth, thereby sequestering atmospheric carbon into the soil profile.

Environmentally, the location is characterized by a semi-arid climate with low annual rainfall, typically averaging between 280mm and 320mm. The soils in this vicinity are generally calcareous earths, sandy loams, or non-wetting Mallee sands, which often struggle with natural fertility. The high project number ("11") in the title suggests this may be part of a larger aggregation of projects on the same property or owned by the same proponent family, a common structure used by the project developer, Agriprove, to manage Carbon Estimation Areas (CEAs) effectively.
