Select Committee on Environment, Food and Rural Affairs Minutes of Evidence


Examination of Witnesses (Questions 40 - 50)

WEDNESDAY 5 MARCH 2008

MR PETER KENDALL, MR ANDREW CLARK AND MR MICHAEL PAYNE

  Q40  Chairman: In your revised proposals for the Action Plan you make every effort to secure derogation from grassland at 250kg/ha of nitrogen. How did you decide that 250 was the right number?

  Mr Payne: There are quite a number of other countries who already have derogations. They are all either for 230 or 250. The figure currently operated in the UK, which the Commission would contend was illegal, is 250. There is a coalescence around the 250, 230 kind of area.

  Q41  Chairman: But what you have described to me is what is—. The question I asked is why is 250 the right number? I am struggling a little bit to understand the practicalities, because, Mr Clark, you also were saying if you looked at this issue on a farm by farm basis you might come up with a different formulation for the use of manures and nitrogen according to the circumstances, and that is finessing it to a degree by farm. I struggle to understand how in the real world you are going to do that? You would have to have a farm by farm assessment for something which, in terms of the movement of nitrate from the surface of the land to the ground water, you have told us in earlier evidence, takes a long time. I am not quite certain how we know what the effect is that we are going to get out by all of this fine-tuning. Coming back to this 250 kilogrammes figure, how do we know that is the right number for grassland?

  Mr Payne: I obviously recognise your criticism, but I am just telling you what has happened. We are working together with ADAS and Defra to develop the scientific case, and I just do not think we are in a position to tell you.

  Q42  Chairman: Let us turn it round the other way. Part of the reason we are having this discussion is that the European Union has decided that 170kg is the right number. I am intrigued to know how we decide that 170kg/ha is the right number. Has somebody done a sort of detailed analysis that on every single soil type, if you put 170 on every year, the water that comes out at the bottom will be guaranteed to be at 50mg/l?

  Mr Kendall: I think the point we have been making is soils are different, areas are different and closed periods and what they are dictating as to storage, we know that farms have a different make-up of arable land and grassland.

  Q43  Chairman: It is all a bit of guesswork really, is it not?

  Mr Payne: Could I just comment on the water coming out at the bottom?

  Q44  Chairman: I am going to ask the Minister the same thing, and if there is anybody here representing the Minister, they had better nip out and tell him that this question is coming!

  Mr Payne: The water coming out at the bottom, Chairman, what you say about ground water is true. Where water drains to surface water, you know the result within a calendar year, so you can monitor and get results, but a lot of it is to do with the wording and interpretation of the Directive, that any derogation should not prejudice the achievement of the objectives, on what scale you have to assess them and there is a lot of political administration, put it like that, in the way these are administered. The issue of how the 170 was arrived at—

  Q45  Chairman: I am just interested in where these numbers come from?

  Mr Clark: The figures come from the Nitrates Directive. Those are the figures set down: 170 and 250.

  Q46  Chairman: I do not blame you if you cannot tell me, because it is not clear to me.

  Mr Clark: Michael may be able to, because he was there when it happened.

  Q47  Chairman: Somebody in the Commission has decided that these numbers are the correct numbers, and I am just interested to know where these numbers have come from. Did Jacques de whatever wake up one morning and think, "Oh, I have the answer. It is 170"? What is the answer? It might be 49, I do not know. I am just asking the question.

  Mr Kendall: I suspect they often look at something that is significantly lower than the current norm and, therefore, they set targets that look to deliver lower outcomes.

  Chairman: I can see this is going to be an entertaining line of questioning when our next witness comes along.

  David Taylor: Going back to cover crops briefly, Chairman.

  Chairman: Mr Tipping is going to ask about cover crops. Mr Tipping, you ask the question about cover crops.

  Q48  Paddy Tipping: What is the case for cover crops on light and sandy soils?

  Mr Clark: We have looked at the evidence, the rationale for introducing cover crops. It seems to be based entirely on an analysis that was undertaken as part of the Nitrate Sensitive Area Regime which was run in areas which were principally sandy and shallow soils, and there, in the context of the early 1990s, late 1980s, it was found to be an effective measure. We have already demonstrated to you with evidence produced by the AIC that the way we farm now in terms of the amount of fertiliser used, the timing of the fertiliser, for example not applying in the autumn, we think the context in which arable farms, horticultural farms are operating is totally different to what it was even 15 years ago, and so we think that the effectiveness of cover crops expected to result from this sort of measure is possibly overstated in that context. Having said that, we can see there is, however, some evidence that cover crops can reduce nitrate loss. We have to recognise that, and so our task is to work with the farming sector in consultation to try and understand how that can be applied so that it works practically with farms, and we see particular problems. We are still in discussion, and we have had good discussions with Defra about this—they recognise it is not a universal panacea in the way that they have suggested—but we see particular problems for the sugar beet sector, for the horticultural sector, some of the high value crops based on vegetables which have unusual regimes—it is not a straightforward rape arable, fallow type approach—and so I think we want to get more underneath the skin of that particular regime.

  Mr Kendall: Can I make a point on the practical side. As I said, on heavy soils you do plough the land early because the weather breaks it down. Where I think we are seeing a change, since the earlier period of work that indicated that light, shallow soils caused leaching, is many of those farmers are either now in agri-farm schemes where they get over wintered stubbles, therefore, they cultivate them deliberately late, or, alternatively, they have understood the impacts of leaching and, in order to keep those nutrients, they plough them late anyhow; so we think that farmers are learning to react properly and therefore behave differently on those soils. Ploughing a shallow or a light soil in January is feasible, but with my heavy Bedfordshire clay you are going to get stuck.

  Q49  Paddy Tipping: Tell me about the conservation and wildlife benefits of over wintering of stubble? There are some, are there not?

  Mr Clark: This is one of the things which the RSPB and ourselves promoted as part of the Entry Level Scheme. I looked at the data last month and found there were about 60,000ha of over wintered stubbles entered into the Entry Level Scheme, which I am sure the RSPB, who will be visiting Peter's farm on Friday, will be very keen to find out about. We are very concerned, in this respect, that cover crops are not only going to be agronomically difficult, they are perverse from a biodiversity point of view unless they are managed very carefully. The requirement to have a green cover might work for nitrates, but in obtaining a green cover you might well end up not having any over wintered benefits for feeding birds, you might well end up having to use extra herbicides to kill off that green cover, you will have had to disturb the ground in the first place to establish the green cover, so you are going to be creating nitrate at that time, and so the perversities of the cover crop option, while in nitrates terms simplistically is good, in terms of the perversities of this measure we are very concerned about them.

  Q50  Chairman: In conclusion, I asked for some information about what had been happening in other Member States and, in terms of storage capacity for slurries, the impression I got was that other Member States had installed anywhere between six or five months capacity, for example, as in the case of Northern France and Brittany, five months in the south. They had already done that. What is your impression about what other Member States have done, and if their farmers have been able to afford enhanced storage capacity against the background when the whole of Europe's agriculture is under the kind of price and input pressures ours are, how have they afforded it?

  Mr Clark: There are three ways in which you can help with this: there is time, there is planning permission and there is grant aid. If you look at Ireland, they have got, I think, it is three, three and a half months' requirement to store and up to 80% grant aid. That is how they can put it in, and I suspect in France they have got 40% grant aid as well, but they have had grant assistance, and we are not going to have grant assistance, as we have been told by the Minister so far.

  Chairman: Okay. That is very helpful. Thank you very much indeed, as always. Now we have got the Minister coming to explain the other side of the story.
