Soil Health

I am coming to that. There is a major section in my speech about our meeting, but I thank the Minister for drawing attention to it.

It is a sad scenario that brings us here today and that caused us to hold our inquiry. Soil is a finite and deteriorating resource. Soil takes a very long time to develop, as we have heard—1 cm of topsoil can take 1,000 years to form, but can be lost in a moment. Topsoil can be washed away into our waterways if the incorrect crops are grown and it is left open to water, and the carbon in the soil can evaporate into the atmosphere.

According to a UK Government report, the UK is losing 2.2 million tonnes of crucial topsoil each year, which costs the economy some £1.2 billion. That is why we must seriously consider the issue. As we have heard, some calculations say that we have only 100 harvests left in certain arable areas of the south-east of England before we cannot grow anything in the soil. We have to do something to reverse that decline.

I do not want to be completely negative. I applaud the Government in some respects, and I particularly welcome their progress on preventing the degradation of the peatlands—we have already heard about that, so I will not talk about it in great detail. I also applaud the Government on their ambition to manage soil sustainably by 2030. That was highlighted in the 2011 natural environment White Paper, but I urge the Minister to speed up the process. The situation is so serious that we need to address it now, rather than thinking, “2030 is a long time way. Let’s not worry about it now.”

As we have heard, the Government signed an agreement at COP 21 to increase soil carbon by 0.4% a year. I am pleased that that is on the agenda, which I applaud. That is great, but please can we hear from the Minister about how we are pushing it forward? It is serious.

It is not all about carbon and climate change; it is really about changing how we think about soil, which is partly what this debate is about. This is the first ever UK debate on soil, and I hope that it will influence how we think about it. Let us start by treating soil as an ecosystem, not as a medium for growing stuff, because we have used and abused it—not everyone has, but it has often been treated that way—and the ethos of EU policies has been about preventing damage rather than restoring and improving the soil. Brexit provides us with an excellent opportunity to change how we approach the issue and think about how to encourage those who work the land to help restore and improve it. The Soil Association calls for organic matter to be increased on arable land by 20% in 20 years. That is quite a challenge, but we should perhaps consider it.

I come now to the issue of monitoring schemes. One of our report’s main findings was that we needed a decent monitoring scheme. After all, if we do not know what is in the soil, how can we tell people what they ought to do about it? Lord Krebs led the way on climate change by means of a proper monitoring scheme, which is what triggered all the work that we have been able to do on climate change. I was delighted to discuss a soil monitoring scheme with our previous Environment Minister, who was keen on trying to get the idea into the 25-year plan. Again, I applaud the Department for Environment, Food and Rural Affairs for doing so.

I am also delighted that our new Minister, my hon. Friend the Member for Suffolk Coastal, who has taken over the mantle, has shown so much interest in the subject that she has already met me for half an hour to discuss it, bringing with her lots more of the brains on her team. I was pleased—it was early in her tenure as

the new Environment Minister—and I am absolutely sure that she was listening. I would like to hear a little about where those ideas might have gone.

I remind everybody that a royal commission on environmental pollution 20 years ago recommended a monitoring scheme, so we have not come very far since then. In fairness, there is an EU soil monitoring programme, but it is done only once every eight or 10 years, and it is quite cursory. A lot of farmers will tell you that they monitor the soil, but they are monitoring mainly the chemicals in the soil—NPK, or nitrogen, phosphorus and potassium—and that needs to be broadened.

We have so much environmental expertise in this country, as we heard at our inquiry. We have got the brains, and much of the work is already being done. The Centre for Ecology and Hydrology has a scheme that it reckons it could roll out tomorrow, with not too much funding, so that we could monitor our soil as an ecosystem and look not only at the chemical content but the organic and carbon content, and all the organisms—thrips, nematodes, earthworms and all the things that I learned about at university years and years ago—that are mentioned much less than they ought to be. We could make a difference quickly.

I do not think that there should be a blame game against farmers. Many of the ways that farmers have been forced to farm have been directed by our policies of low-cost food. That is why many farmers have gone down the route of monoculture and least-cost production, and our European Community policies have encouraged that. In fairness, lots of farmers are already doing exceptionally good work.

One farmer in my constituency, Tom Morris, is a great friend. He is an organic dairy farmer who has always farmed for the soil. At the Dairy UK breakfast this week, I met a fascinating chap called Lyndon Edwards, who is also an organic farmer, from Severndale farm in Chepstow. He goes around giving workshops showcasing his good practice to other farmers, and has just been to my constituency. We should encourage a lot more of that; I think that people would be receptive to it. One suggestion is that perhaps the Agriculture and Horticulture Development Board, the levy board, might be able to put some emphasis on research into soil analysis, to help build up our picture.

More green cover and grass—I am a great advocate of grass—in growing rotations, more deep-rooted crops and many other simple things can be done to address the situation. We should be getting on with it. I reiterate the calls for more joined-up thinking across Departments, particularly between DEFRA and the Department for Business, Energy and Industrial Strategy, so that when we form our policies on crops grown for energy production, we choose crops that will not destroy the environment. Maize needs serious consideration. I am sure that the Minister is listening.

There is a massive link with well-being and the health of our soil, which links the issue to the Department of Health as well. It is important to have healthy soil and a healthy ecosystem, which basically means a healthy us. That is a no-brainer. I am heartened by the groundswell of interest in the issue. It is not just our Committee here in London; I meet many people who talk about soil, including farmers. I held an environment forum in Taunton last week on flood resilience, but the subject of soil and how better to look after it to control flooding kept coming up.

Soil should not be a Cinderella story. I will end with a final thought that might concentrate our minds. Research in the US has just discovered the first potential in 10 years for a new antibiotic. Guess where? In the soil. That should give us all plenty of food for thought. I know that the Minister, with her scientific mind, will realise how important it is. We neglect soil at our peril.
