Thesis title

Physical behaviour of Greenlandic rock flour, soils and rock flour amended soils — particle, pore-network and mechanical properties

Summary of the thesis

Greenlandic cultivated soils generally exhibit a relatively coarse texture, resulting in undeveloped and structure-less soils. However, the high soil organic matter contents of these Arctic soils can partly make up for those deficits. The addition of naturally occurring, fine-grained mineral material (glacial rock flour, GRF) as a soil amendment may improve soil quality for agricultural production; it may counteract the detrimental effects of climate change and potential changes in land use and management on the soil organic matter pool.

The thesis investigates the current situation of Greenlandic pasture soils in terms of soil-structure development and soil-mechanical stability by using gas transport parameters and compression tests, respectively. In addition, it discusses the use of glacial rock flour as a soil amendment, its physical and chemical properties and its effect on mechanical soil stability and pore-network tortuosity.
