Course contents:
Soil-forming factors; climate, living organisms; parent material; topography  (relief) and time, determine soil development and which chemical and physical properties characterize the soil. On a local scale, it is especially landscape (topography/relief), vegetation and geological deposition type that are decisive. In this course, it is these soil forming factors we will focus on. We emphasize the development skills in describing, testing and analyzing morphological, physical and chemical soil properties. Connecting what we observe and analyze in the field with what laboratory analysis tell us is central to the course. We follow soil samples from field to laboratory. Interpretation of these soil characteristics in a landscape context is important for solving many issues related to the earth's ecosystem function / services.
Learning outcome:
After completing the course, the student should be able to carry out a standard soil profile description, field classification and sample soil for standard chemical and physical analysis. Students will know how to conduct a soil survey and through this obtain experience with soil variability in soil properties observable in the field. Students will perform their own laboratory work for both soil chemical and soil physical properties. The students should be able to measure and calculate various physical and chemical soil parameters, and be able to connect information on physical, chemical and morphological soil parameters to different soil ecosystem functions. Group work is central to the course and will provide training in collaboration. The group work will help the students become better at discussing, and value and respect different input and competence so that the goal - the report - is better and the work becomes more efficient.
Learning activities:

Tree weeks in August will, in full, be used for intensive field and laboratory work. The field and laboratory work will be conducted group wise and will be followed by key lectures in plenum. The fieldwork consists of; 1) soil profile descriptions and field classification 2) in situ measurements of some soil physical parameters such as moisture and temperature 3) soil sampling for chemical and for soil physical analysis in laboratory 4) soil survey/mapping of a limited area.  The laboratory work includes preparing (drying and sieving of soil) for and carrying out some chemical and physical soil analysis. These analyses include particle size distribution, determination of volumetric conditions in soil, pore-size distribution, measurements of water and air conductivity in soil, pH, organic matter content by loss on ignition, cation exchange capacity (CEC) and some extractions of Fe and Al.  In the autumn parallel two hours, each week will be used to complete the analysis, lectures and processing of the data for the final report. Students must organize the writing of the group report themselves (each student should allocate 100 h to report writing in the autumn parallel).
