RockFlour

RockFlour (GreenLandbrug – Unleashing Greenlandic Rock Flour for a Climate-Neutral Danish Agriculture) is a collaborative research and innovation project exploring the potential of Greenlandic glacial rock flour as a nature-based solution for more sustainable agriculture.

The project investigates whether this naturally occurring mineral material can improve soil quality, enhance nutrient availability, increase water retention, and reduce agriculture's environmental footprint. In addition, the project examines the role of rock flour in carbon sequestration through enhanced weathering processes that permanently remove carbon dioxide from the atmosphere.

By combining laboratory studies with field-scale testing, the project aims to evaluate how glacial rock flour can be integrated into Danish farming systems as a complement to conventional agricultural inputs. The research focuses on its effects on crop production, soil health, nutrient cycling, greenhouse gas emissions, and nutrient losses to the environment. Findings from the project will help assess the feasibility of using rock flour as a tool for climate mitigation and resilient agricultural production.
