Dr William Stiles

Knowledge Exchange Fellow

Contact Details


From the Knowledge Exchange Hub at IBERS, Will provides current and applicable scientific knowledge to the agricultural industry through Farming Connect which is a high profile, integrated project supplying focussed training, support and advice, delivered through a pan-Wales programme of knowledge transfer activities, specialist advice and support for innovation. A key objective of Farming Connect is to increase the emphasis on business-focused behaviour, therefore improving profitability, competitiveness and environmental performance of farm, forestry and food businesses in Wales. Farming Connect is funded through the Rural Development Plan (RDP) 2014 - 2020, which is funded by the European Agricultural Fund for Rural Development and the Welsh Government.

Through Farming Connect Will has produced numerous technical articles on a range of topics, with particular focus on climate and environmental change, to disseminate current scientific research to the agricultural industry. He is also involved in the development of farmer-led agricultural research through the European Innovation Partnership (EIP) scheme in Wales .

Additional Information

Will completed a PhD in ecology and biogeochemistry at IBERS, Aberystwyth University, with a thesis entitled: Identifying key environmental factors affecting primary productivity and ecosystem services in the uplands.

Prior to this, Will Studied for a BSc (Hons) in Ecology & Environmental Management (joint honours) at the University of Worcester, graduating with First-class honours, before working on a project at Cranfield University for the HGCA to develop a calibration model for measuring phosphorus in UK soil, using visible and near infrared spectroscopy.



Research interests include ecological and soil based responses to system biogeochemical change, such as in response to nutrient, particularly nitrogen (N), pollution. Specifically, this has focused on the effect of phosphorus (P) availability in situations of chronic N pollution and the role of P limitation with regard to influence on plant diversity, soil biology, carbon fluxes and soil carbon storage potential.
