Sofia Delin
Associate professor in Soil Science/Plant Nutrition.

Presentation

Research leader responsible for the field trials at Lanna reseach station. Researcher within applied plant nutrtion, mainly concering fertilization with organic residues, manure and optimised fertilization for minimized leaching and nitrous oxide emissions. 

Professional interests

  • Nitrogen mineralisation and fertilisation effects (N & P) from organic fertilizers
  • Optimized manure application for improved nitrogen efficiency
  • Effects of fertilisation on nitrogen leaching and nitrous oxide emissions.
  • Within-field variations in soil nitrogen mineralisation 

Research projects

  • Fertilization with minimized nitrous oxide emissions under Swedish conditions
  • Effects of digestion and acidificationof animal slurry on nitrous oxideemissions
  • Variation in biogas digeste charcteristics and effects on ammonia emission and fertilization effect
