Special Issue On Organic Phosphorus

Move fast folks….. I am delighted to inform you that the complete special issue entitled Organic Phosphorus: Potential Solutions for Phosphorus Security in Plant and Soil, from our Workshop, is now complete and available free to download for 1 month only now here.  This was lead edited by mysef with Daniel Blackburn and Philippe Hinsinger, plus it includes for papers from my team.

A related paper from the Workshop by  myself and Tony 'AF' Harrison and Ben Turner is also available to read in the European Journal of Soil Science Anniversary Issue here.

That’s me signing off now from OP2016 Workshop Organizing. Last one from OP2016 turn off the lights….. Next stop OP2019 Sweden…..

Cheers, Phil

Welcome Anchen to he mysterious world of Phosphine!

It was my pleasure to welcome Anchen Kehler to Lancaster University today. Anchen has recently started studying for her PhD with Dr Martin Blackwell at Rothamsted Research and myself as her supevisors. Anchen is focussing on he mysterious world of phosphine gas, a little-researched compound of the phosphorus cycle that represents a potentially interesting means of cycling phosphourus that we really don't undertsand too well. Anchen is part of the STARS National Doctoral Training Centre, and for most of hear time is based at North Wyke in Devon. Welcome Anchen, you have some great potential and a really interesting subject!

Congratulations Dr Kirsty Forber......

I’m delighted to share the news that my latest PhD student (co-supervised with Dr Mary Ockenden) to complete is Kirsty, who recently defended her thesis on Phosphorus Transfers to Water under Climate Change. Her examiners were Professor Helen Jarvie and Dr Alona Armstrong. Well done Kirsty, happy days.  we have to share the results with the world and get them to wake up to the issues.....

Welcome Andy

Andy Tweedy has recently started his PhD working between myself and Marc Stutter at the James Hutton Institute and Louise Walker at EMS. Andy has an exciting project studying phosphorus mobility in soils as affected by carbon and nitrogen. He is part of the STARS Soil CDT #starsoil. Welcome Andy I’m confident you will go a long way!  Here are some pictures of our recent gathering in Lancaster.

Extreme Climate, Extreme Phosphorus

Yesterday I spoke in an Webinair hosted by the North American Sustainable Phosphorus Alliance.  A copy of the webinar can be viewed here - thanks to Matt Scholz from the Alliance for sharing.  Regards, Phil

Thank you Deborah: where did the 8 years go?

Today I said goodbye to Deborah Bellaby who has been working on the EdenDTC team with me for 8 years. It's been terrific to work with Deborah and I wish her all the best for her new job. Where did the time go?

An uncertain future? Major agricultural changes required to mitigate phosphorus losses under climate change

We have just published in Nature Communications a sobering reminder about the prospects of phosphorus transfer from land to water in the future under climate change.  Mary Ockenden, my Post Doctoral research fellow, skillfully led the paper and the abstract of the paper follows, with a link to the open access version of the paper here and a PDF here.

Phosphorus losses from land to water will be impacted by climate change and land management for food production, with detrimental impacts on aquatic ecosystems. Here we use a unique combination of methods to evaluate the impact of projected climate change on future phosphorus transfers, and to assess what scale of agricultural change would be needed to mitigate these transfers. We combine novel high-frequency phosphorus flux data from three representative catchments across the UK, a new high-spatial resolution climate model, uncertainty estimates from an ensemble of future climate simulations, two phosphorus transfer models of contrasting complexity and a simplified representation of the potential intensification of agriculture based on expert elicitation from land managers. We show that the effect of climate change on average winter phosphorus loads (predicted increase up to 30% by 2050s) will be limited only by large-scale agricultural changes (e.g., 20–80% reduction in phosphorus inputs).

Our press team did a good job in promoting the story with this simple short video and we achieved National BBC Radio 4 attention on Farming Today as well as other channels.  

This work reflects the importance of the long term data from the National Defra Demonstration Test Catchments and the NERC NUTCAT projects, all coming together. The more you think about thsi work and its implications, the more serious are the implications.  This is just the beginning......
