Professor Tony Edwards

Scotland's Rural College

Research Interests

My research interests include all aspects of soil nutrient cycling, especially in relation to phosphorus and interactions with land use together with general environmental chemistry. This work has involved wide collaborate both nationally and internationally.

Research Projects

  • Micronutrient management strategies in organic systems: How to utilize local and site specific resources for sustainable crop and animal production of high quality products? Funded by Swedish Research Council for Environment, Agricultural Sciences and Spatial Planning (Formas)
  • Improving the sustainability of phosphorus use in arable farming, Link project (Defra/RERAD/HGCA)

Other responsibilities include being Associate Editor for:

  • Agriculture Ecosystems and Environment
  • Regional Environmental Change
  • European Journal of Agronomy

Reviewing projects for Irish EPA, Italian Government, Defra and Scottish Government.


  • BSc Geology/ecology (Sunderland)
  • PhD Soil Science (Aberdeen)
