Arctic Soils

ECTS credits: 5 ECTS

Course parameters:
Language: English
Level of course: PhD (we will allow MSc if seats are available)
Semester: (Autumn) August 2021 (14-21 August 2021)
Hours per week: One week of preparatory reading, 8 days expedition to Greenland, preparation of course report
Capacity limits: 6 PhD students

Objectives of the course:
The course provides students with an understanding of the positive impact of climate change for agriculture in subarctic areas. The course will provide a fundamental understanding of the soil and environmental factors which may influence agricultural production in South Greenland. 

Learning outcomes and competences:
At the end of the course the student should be able to:

  1. Explain the importance of soil physico-chemical properties for agricultural production in South Greenland
  2. Explain the importance of environmental factors for agricultural production in South Greenland
  3. Use the appropriate methodology to quantify soil physico-chemical properties
  4. Suggest practical solutions for intensifying agriculture in South Greenland

Compulsory programme:
The rapid climate change, which is taking place in Greenland, has serious repercussions for animal and plant life throughout the country. The rising temperatures can however, offer better conditions for future agricultural production in Greenland because of increased summer temperatures and prolonged growing seasons. Land use, though, is also influenced by many other factors such as soil quality and the increasing lengths of dry periods during vegetation season.

The course focusses on insight understanding of farming conditions in South Greenland. Physical and chemical properties of South Greenlandic soils will be investigated:

  • Soil depth
  • Soil texture
  • Soil organic matter content
  • Bulk density
  • Soil water retention
  • Plant available water
  • Soil aeration
  • Hydraulic conductivity
  • pH
  • Micro and macro nutrient content
  • Soil water repellency
  • Soil microbiology

The students will visit selected farmers and field sites in South Greenland. Lectures, exercises and soil sampling activities will be performed in the field. Also, glacial rock flour deposits will be located and sampled. Large scale field experiments with addition of glacial rock flour will be visited and sampled.

Results from the exercises will, together with results from ongoing experiments on Greenlandic soils, will be an integrative part of the final project report.
