Soil Science Area at CEH

CEH's new Science Strategy identifies three interdependent, major societal and environmental challenges: Securing the Value of Nature, Building Resilience to Environmental Hazards, and Managing Environmental Change. We're delivering our strategy by Science Areas and underpinning activities, and over the next few weeks we are profiling each of these on our blog.

This post focuses on our Soil Science Area, which is led by Professor Bridget Emmett. Sound scientific knowledge of soil functioning is essential to assure UK and global security for food, fuel and water.


The multidisciplinary research at CEH makes us ideally placed to develop new understanding of soil function and the relative importance of soil biota, physical and chemical properties and their emergent properties across scales. We apply this knowledge for improved sustainable management of soil and the ecosystem services soils provide.

Soils are critical for life. As well as providing nutrients and water to grow food, they help regulate floods and droughts, they play an important role in modulating the greenhouse gases which control our climate, and they support a large and diverse biological community.


But such societal benefits depend crucially on soil quantity and condition, both of which are at risk from threats such as over-exploitation, contamination and climate change. Understanding and managing the diverse and sometimes conflicting services provided by soils demands an integrated, multidisciplinary approach.
CEH's soil science expertise is multidisciplinary and allows us to develop new
understanding across scales.


CEH's current and future research objectives include new tools and data, for example we are developing in partnership a UK Soils Observatory and an enhanced mySoil app. We are aiming to increase understanding, for example of the links between biological and physical structure of upland soils and their implications for water and carbon services. We will quantify the impacts of land use change to energy crops on soil carbon stocks and greenhouse gas emissions for the UK, and we are developing web interfaces with partners to deliver real-time soil sensor data.

The top 10 most viewed CEH news & blog posts of 2013

We hope you've found our content interesting and informative throughout the year but, of course, not everything will be to everyone's tastes. Here is a little (slightly unscientific!) insight into what news and blogs you were reading the most in 2013, in traditional reverse order:

Top 10 most viewed news stories


10. Distinctly autumnal feel to May as below average temperatures persist
The cold spring was still hanging around, but a warm summer wasn't too far away.

9. Ecologists get first bumblebees' eye view of the landscape
Scientists produced the most detailed picture yet of how bumblebees use the landscape, thanks to DNA technology and remote sensing.

8. Introducing the Hydrological Outlook
CEH and a number of partners had been working for a while on developing a long-range hydrological forecast for the UK.

7. Cocktail of multiple pressures combine to threaten the world's pollinating insects
Not one cause, but a combination of pressures including pesticides, disease and loss of food resources are threatening insect pollinators such as bumblebees and honeybees.

6. Are tropical forests resilient to global warming?
Tropical forests are less likely to lose biomass in response to greenhouse gas emissions over the 21st century than may previously have been thought.

5. Britain's rarest freshwater fish, the Vendace, reappears in Bassenthwaite Lake
The vendace made an unexpected reappearance in Bassenthwaite Lake in north-west England, more than a decade after being declared 'locally extinct'.

4. Tropical rainforests, 'lungs of the planet', reveal true sensitivity to global warming
The amount of carbon dioxide absorbed or produced by tropical rainforests varies hugely with year-to-year variations in the climate, revealing their vulnerability to climate change.

3. Smarter use of nutrients can help protect human health and the environment
A new report highlighted how humans have massively altered the natural flows of nitrogen, phosphorus and other nutrients, and how better management can help protect the environment, climate and human health.

2. Puffin count on Isle of May NNR gives surprising result
Despite severe spring weather, the worst fears for puffins weren't realised: a census revealed that Atlantic puffin numbers on the Isle of May National Nature Reserve off Scotland's east coast were at similar levels to 2009.

1. Mobile phone app to help monitor UK's native ladybirds after foreign invasion
iRecord Ladybirds, a free mobile phone app, was launched to help the public record ladybird species, including the invasive Harlequin ladybirds. All interest in the app, and a fantastic number of records, have been gratefully received by our scientists!

Top 10 most viewed blog posts


10.  INTECOL news round-up: pollinators, citizen science and land use
A number of CEH staff presented at the 11th INTECOL Congress in London, the world's largest international ecology meeting, and this post tried to highlight what they said.

9. Cleaner air for all - searching for solutions to air pollution at Green Week 2013
Air quality was the theme for this year's event in Brussels, and CEH expertise was on hand to lead and join in with some of the discussions.

8. We're going on a Bug Hunt!
Science can be fun too, as ecologists and pupils taking part in a hugely successful Bug Day at a school near Rugby can confirm.

7. Filming at CEH's met site in Wallingford
Wet weather at the end of 2012 and into 2013 meant a busy start to the year for the CEH Press Office, with several media requests to interview our hydrologists.

6. Building environmental links in Beijing
Environmental researchers in China and the UK have signed a memorandum of understanding to explore collaboration opportunities. Recovery of polluted environments, water management, food security and soil management were all discussed during a meeting in April.

5. Biodiversity offsetting - the science behind the policy
More information on how CEH provides independent and impartial scientific advice for the tricky topic of biodiversity offsetting.

4. Nitrogen narratives in Nairobi - confessions of a reluctant blogger
Professor Mark Sutton experiences life at the sharp end of the science-policy debate.

3. A revolution in ladybird recording
Ladybirds are charismatic insects and so it isn't surprising that people in Britain have been enthusiastically recording them for centuries.

2. Assessing the 2013 Atlantic Puffin wreck
Our two most viewed blog posts of the year are actually on the same topic, indicating the huge interest at the time, and some of the uncertainty, around a puffin wreck in Eastern Scotland and NE England.

1. Puffin wreck in Scotland
Multiple unusual deaths of puffins were noticed on the east coast of Scotland NE England in the last week of March. One of the world's foremost authorities on puffin, Professor Mike Harris, gave insights into the emerging story.

You can read more about CEH research and news over the past twelve months in our annual review of the year on the CEH News Centre. Just a final thanks to all our contributors and, of course, to our readers. More to come in 2014 but in the meantime, Happy Christmas and best wishes for the New Year!

Nitrogen narratives in Nairobi – confessions of a reluctant blogger


Professor Mark Sutton from CEH has been in Nairobi, Kenya, this week at the United Nations Environment Programme Governing Council. Here he reports back on experiencing life at the sharp end of the science-policy debate.

Here you find a reluctant blogger. I am currently writing this late at night, after a day full of meeting people of so many nations, many disciplines and many roles.

Half the day has been spent talking - trying to better understand what makes people tick, understanding why they hold their positions. Half the day has been spent talking to press colleagues, and lining up interviews with various newspapers, radio and TV channels - often by mobile phone. Not all of these interviews will come off, but a fraction will, and through them we can reach a much wider audience than our scientific papers and reports. The other half of the day has been spent reading and writing emails, trying to keep up with everything that is going past. (All of this would not have been possible without the great support from UNEP colleagues in DEPI, DCPI and DEWA divisions).

As you can see my maths does not add up –  but you hopefully get the right impression.

In fact impressions are everything here. As a scientist one can spend a long time designing experiments, collecting and interpreting data - refining the message for a scientific audience. But here I am, at the Governing Council of the United Nations Environment Programme (UNEP) in Nairobi. 1000 delegates have joined together to address environmental issues, to review the UNEP programme of work, and even make a few decisions about how to manage the planet's environment better.

So, what about making impressions. My point is that the delegates present here are nothing like a scientific audience. Peer review, statistics, lovely data series, and even new conceptual paradigms, don’t count for much around here. As several people here have commented, by far the strongest thing is "the narrative". Yes, it's great to have the scientific data and the evidence in the background [and really it is VERY important!]. But the thing that grabs their attention is a good story, where we simplify our science to its barest essence, turning complexity into something that everyone can understand.

This seems to be my job for the week. I am here to launch a report, "Our Nutrient World", commissioned by UNEP. It's about "the challenge to produce more food and energy with less pollution". We need nutrients, like nitrogen and phosphorus, to make crops grow and feed the world. The problem is that most of these nutrients leak out to the environment, weaving a web of air, water and soil pollution, contributing to climate change and threatening biodiversity. So let's manage nutrients better, let's think about a suitable goal, and let's get people talking.

In fact we have 10 key actions in our pack of options, from farming management techniques and sewage treatment to the ambition to recapture NOx (nitrogen oxides) into useful products.

But not many people want to talk about smart manure spreading. So I focus on what people do want to talk about. And that is food. In a way it's their call.

Throughout the week I’ve been highlighting the fact that 80% of the harvested nitrogen in the world ends up feeding livestock rather than people, that Europeans eat 70% more protein than needed for a healthy diet, and that, for many of us on the planet, we live in a world of "food luxury" rather than struggling to maintain a minimum "food security".

It’s a great discussion for dinner and just about anywhere you like. And before you know it, the horse-meat scandal has become linked up with nutrient management. People are thinking about their food choices. We have the demitarian option on the table, and the journalists and radio producers want to hear about it.

So it seems somewhat ironic when a lunchtime radio presenter says that: surely I am speaking to the wrong audience. Surely the team from "Our Nutrient World" should instead have been making recommendations to farmers...

And, of course we are.  But if we had only done that, then no one would have been listening. The food debate has given nitrogen an opening - and a chance to explain what we can do about this pan-dimensional problem.

It’s a challenge that crosses all global change issues. We need nitrogen, but we need to manage it better. And really: every citizen needs to know nitrogen. Because until they do, the politicians will not be empowered to make decisions, and start taking the local, national and intergovernmental conversation to the next stage.
