Sigrun Dahlin

I have over the years been responsible or contributed to courses and course modules offered to a range of students by the Department of Soil and Environment, mainly basic soil biology modules (all programs) and applied soil science for the landscaping sector (landscape architect program).  

From 2024 I am responsible for the course BI1350 Crop Production - soil and crops (Växtproduktion – mark och grödor).

• Sustainable cropping systems
  - agroforestry
  - UPSCALE push-pull
• Nutrient flows on farms as affected by management
• Nutrient supply via by-products and its effects on crop production and quality, and on soil chemical and biological variables
• N dynamics in the soil-plant system including symbiotic N2 fixation 
• Management effects on cadmium in soils and crops
