7th International Phosphorus Workshop, IPW7 - Uppsala, Sweden, 9-13 September 2013 - Programme and Book of Abstracts

As organisers of the 7th International Phosphorus Workshop – also known as IPW7 – it is our great pleasure to welcome you to Uppsala on 9-13 September 2013. The workshop is being organised jointly by the Departments of Soil & Environment and Aquatic Sciences & Assessment at the Swedish University of Agricultural Sciences, the Swedish Board of Agriculture, and the Department of Physics, Chemistry and Biology at Linköping University. We are very excited to report that there will be many delegates at this meeting. More than 130 participants from about 25 countries will attend and contribute to the different sessions, including the workshop discussions. We are dedicated to doing our best to making IPW7 memorable for all of you and we hope that the days in Uppsala will provide participants with inspiration for future research and practical applications. With the help of scientific research in close cooperation with practitioners (regulators, advisors, farmers etc.), it may be possible to combine safe and profitable food production with good environmental quality and sustainable use of natural resources. The IPW7 meeting will provide information about phosphorus (P) management in a changing world, including the importance of manure and cropping systems, identification and implementation of mitigation strategies to reduce P losses, transport pathways of P from soil to water, and monitoring, modelling and risk assessment at different scales. We are proud to present this volume of abstracts, which contains more than 120 abstracts, covering a wide range of topics within the themes of IPW7. Active participation, intense discussions, new insights and new contacts are some of the features that we expect to characterise IPW7. We also hope that participants at this meeting will ensure that IPW7 forms an important link in the chain of IPW meetings that started in Wexford, Ireland, in 1995. On behalf of the organisers, we would like to express our gratitude to all those who have contributed to IPW7. Many people have enthusiastically participated in the planning and preparation of these five days in Uppsala, including people supporting the Organising Committee, members of the Scientific Advisory Committee, and Johanna Thyselius Nilsson and her colleagues at the Conference Secretariat. Thank you all for your positive attitude and fantastic support! Mary McAfee checked the language in many of the submitted abstracts. Thank you for your fantastic help and fast response! Financial support was received from the Swedish Research Council Formas, Yara, the Swedish Plant Nutrition Foundation, Uppsala Water Center, the Faculty of Natural Resources and Agricultural Sciences (SLU) and Nordkalk Corporation, to whom we express our sincere thanks. Finally, special thanks to you, the delegates, for supplying the input needed for a successful scientific meeting through high quality presentations during oral and poster sessions. We wholeheartedly welcome you and hope that you find IPW7 as successful and rewarding as we envision it to be.
