“Sustainable utilisation of manures and residue resources in agriculture”

Keynote Speakers



Sub-theme 1: Advances in technologies

Prof. Vincent O’Flaherty

School of Natural Sciences, National University of Ireland Galway

Vincent O’Flaherty is a professor of microbiology at the School of Natural Sciences, National University of Ireland Galway. He has 25 years’ experience in the area of anaerobic biofilm and microbial ecology research, focused on: anaerobic biofilm reactor technology for bio-refining, energy production and wastewater treatment; control of biofilms in infectious disease settings and the microbial ecology of anaerobic biofilms and soil ecosystems. Prof. O’Flaherty is the scientific leader of the Sustainability Pillar of the Dairy Processing Technology Centre (www.dptc.ie) funded by the Irish Dairy Industry and Enterprise Ireland and is actively involved in several other projects focused on the development of an indigenous Irish sustainable biomass and bio-refining sector. His group has been heavily involved in the development and application of low-temperature anaerobic biofilm technology towards commercialisation and technology developed in his lab was the basis for the establishment of NVP Energy (www.nvpenergy.com).

Prof. O’Flaherty is also a co-founder of a spin-out company from NUI, Galway - Westway Health, which was formed in 2012 and is focused on the development of an exciting and novel antimicrobial platform for infection control in veterinary and human settings (www.westwayhealth.com). Prof. O’Flaherty teaches microbiology and environmental biotechnology to undergraduate and postgraduate students at all levels, and is head of the School of Natural Sciences. He has published over 250 scientific communications, including 105 papers in leading international, peer-reviewed, journals. http://scholar.google.com/citations?user=dxuO7AYAAAAJ&hl=en&oi=ao


Sub-theme 2: Crop nutrition

Prof. Lars Stoumann Jensen

Dept. of Plant and Environmental Sciences, University of Copenhagen

Prof. Jensen holds a chair in Soil Fertility and Recycling of Organic Waste Resources at UCPH. His research interest and responsibilities covers all aspects of soil fertility, in particular how decomposition processes and nutrient turnover in agro-ecosystems are affected by organic matter inputs, including crop residues, animal manures, composts, sludges and other wastes applied to soils. Studies focus on fundamental biogeochemical processes controlling nutrient and contaminant availability and mobility (often studied using isotope methods), but also more applied aspects like organic waste processing, fertilizer value and formulation, effects on soil quality, gaseous emissions and nutrient losses to the environment. Simulation modelling of soil C and N turnover as well as cropping system productivity and environmental effects, both in the short term (within one growing season) and in the long term (at the cropping system rotation level)  as well as the very long-term trend in soil humus have also been covered in his research.

Prof. Jensen heads the Soil & Waste research group with approx. 25 staff, and has recently coordinated the EU-FP7 Marie Curie training network ReUseWaste. He is a member of the EU Nitrogen Expert Panel and of the EIP-Agri Focus Group on Nutrient Recycling.  For details of Prof. Jensen’s research publications and activities, please refer to his homepage at UCPH http://plen.ku.dk/english/employees/?pure=en/persons/184737.



Sub-theme 3: Gaseous emissions

Prof. Claudia Wagner-Riddle

School of Environmental Sciences, University of Guelph

Claudia Wagner-Riddle is a Professor of Agrometeorology at the School of Environmental Sciences, University of Guelph, Canada. She is an expert in application of micrometeorological flux techniques to measure greenhouse gas emissions (GHG; methane, nitrous oxide and carbon dioxide) from agriculture. Her recent research includes characterization of GHG emissions associated with on-farm biogas production (methane from anaerobic digestate storage and nitrous oxide emissions following digestate application to soils) and assessment of net GHG emissions from annual and perennial dairy cropping system. Prof. Wagner-Riddle is an editor of the international journal Agricultural and Forest Meteorology since 2012 and associate editor of the Journal of Environmental Quality since 2011. She is a member of the Scientific Advisory Group to the 4R Quantification Module Strategy, The Fertilizer Institute and International Plant Nutrition Institute,

United States; the Technical Committee GHG Inventory: Livestock, Environment and Climate Change Canada and was Chair (elected position) of the Climatology and Modelling Section of the American Society of Agronomy in 2013/2014. Prof. Wagner-Riddle has published >100 papers, has had 2724 citations and has an h-index of 26 (Google Scholar).



Sub-theme 4: Soil & water quality

Dr. Gary Feyereisen

USDA-Agricultural Research Service, Minnesota

Dr. Feyereisen is a research agricultural engineer at the USDA-ARS Soil and Water Management Research Unit, St. Paul, MN, who investigates nutrient transport processes and management / conservation practices designed to minimize agricultural impacts on water quality while optimizing production.  He is currently working in the areas of tile drainage and manure management with an emphasis on reducing nitrate-N and dissolved P losses from intensively managed dairies.  His lab is investigating strategies to optimize N removal in denitrification beds while simultaneously effecting P removal.  He has published 42 refereed papers and served as an associate editor for the J. Environmental Quality.  He has served as Chair of the Multistate Research Coordinating Committee and Information Exchange Group, Drainage Design and Management Practices to Improve Water Quality, and for the American Society of Agronomy’s Managing Denitrification

in Agronomic Systems Community. Additionally, Dr. Feyereisen has inspired others to share their technical expertise in the developing world by speaking of his technical / social engagement in this realm.  Prior to entering graduate school as a non-traditional student, Dr. Feyereisen spent 20 years in industry as a processing plant engineer, energy manager, and new product development manager.



Sub-theme 5: Adoption and impact

Mr. John Williams

ADAS Boxworth, Cambridge

John Williams is a principal soil scientist with ADAS and his research interests include nutrient management and the mitigation of agricultural diffuse pollution of the air and water environments. Mr Williams has detailed knowledge of national fertiliser recommendation systems having led the revision of the organic manures chapter in AHDB’s Fertiliser Manual (RB209) for the UK. John was a Work Package Leader for Defra’s GreenHouse Gas Platform Project AC0116 and the WRAP/Defra/Zero Waste Scotland/WRAP Cymru DC-Agri project. Mr Williams also chairs Defra’s Research Expert group for the Greenhouse Gas Platform projects. He co-authored the MANNER-NPK nutrient decision support system and is a Technical Adviser for the UK water Industry’s Bio-solids Assurance Scheme.
