Soil Health

Debate between Mike Weir and Rebecca Pow

Thursday 17th November 2016 Westminster Hall

[Mike Weir (Angus) (SNP)]

I am very happy to appear under your chairmanship this afternoon, Mr Bone, and to learn so much about what is happening in “The Archers”.

I should perhaps start by declaring an interest, because, like the hon. Member for Taunton Deane (Rebecca Pow), I am a keen gardener. I am an organic gardener and from that I understand the necessity for healthy soil; it is only with a healthy soil that it is possible to have healthy plants, particularly fruit and vegetables. However, healthy soil is not only the growing medium, as she rightly said, but extends the biodiversity and the species in a garden. I have many species of birds in my garden. In fact, at times I think that the entire species of Spuggies and Brechin lives in my garden, because there are so many of them there; for the non-Scots, that is house sparrows.

It is important that we get this right, because if we do not have healthy soil there will be an impact on food production and on species. Later, I will say something about the carbon in the soil.

In introducing the very good report by the Select Committee, the hon. Member for Wakefield (Mary Creagh) made the valuable point that the report is not just about soil as such, as a growing medium, but about soil that has been contaminated as a result of things that have happened in the past, which was a point made very powerfully by the hon. Member for Rochdale (Simon Danczuk) in referring to the Turner Brothers factory. However, it is not just in post-industrial landscapes that such contamination is a problem. Even in my area, there are old buildings that have had industrial or farming uses and that are full of asbestos and various other contaminants.

There are also problems with former Ministry of Defence facilities, because in many periods, specifically in the immediate post-war period, old aircraft were dismantled and waste was put into pits and similar things. For example, Dalgety Bay in Fife has had an ongoing and serious problem with radioactivity from some of the machinery that was dumped just off the coast. Also, much machinery was buried on old military bases throughout the country.

One of the problems is a lack of record-keeping. It is sometimes very difficult to know what contaminants are actually on these sites, which makes it extremely difficult to clean them up for agricultural or development purposes. There is no easy answer to that problem, and I appreciate that it is not the current Government’s fault that in the 1940s and early 1950s records were not necessarily kept, or that records from that time have since been lost. Also, sometimes the difficulties in this regard were not fully appreciated. Nevertheless, we have to deal with that situation now, because soil is so important; indeed, it is increasingly important to us.

The hon. Member for Taunton Deane made a very powerful speech about the necessity for good soil. I specifically liked one point she made, namely, that soil is not an innate substance. I do not know if she has read the excellent book, “The Running Hare: The secret life of farmland”, which I understand recently topped the bestselling list. It is a fascinating book about someone who is trying to regenerate a piece of farmland—a couple of acres—with natural resources, in order to bring back hares, which have disappeared from many parts of modern farmland.

One of the things that the author does first is to dig a square metre in a field to discover how many earthworms are within it and to compare the number with that of neighbouring farmland. Of course, because the land has been chemically farmed, there are very few earthworms. One of the things that happens in the book is that earthworms come back. In turn, that leads to hares coming back; without giving away too much of the plot, they do come back. However, other animals are also brought in, including smaller animals and birds, and birds of prey, and the farmland is regenerated as a result. Throughout the book, the author compares his farmland to the neighbouring farmland, which he refers to, perhaps unkindly, as the land of “the Chemical Brothers”, who are not doing what he does. The book is interesting in showing how relatively simple changes can bring about a substantial difference to farmland.

[Rebecca Pow]

I am so pleased that the hon. Gentleman is highlighting this point. I have not read that book, but I know about it and will now read it. It makes the case for the call for the monitoring scheme to include much more than just chemicals; we should even count the earthworms in a quadrat of soil. He is making a very powerful point.

[Mike Weir]

I thank the hon. Lady for that intervention. It is a very good point and what she has suggested should be done.
