Agriculture Bill (Fifth sitting)

Baroness Chapman of Darlington Excerpts

Tuesday 30th October 2018 Public Bill Committees

[Mr Goodwill]

I oppose amendment 72, not because I am against enhancing soil health in our country, but because I believe the amendment would act against some of our other objectives. As a farmer I manage soil, and as part of my agriculture degree I spent a year studying soil science. Although it is easy to define animal health—it is the absence of disease, or a state in which production from the animal is maximised—it is much more difficult to define soil health. As an intensive arable farmer, I know that the healthiest soil is the most productive soil. Therefore, levels of nutrients—nitrogen phosphate, potash and sulphur—should be optimised to produce optimal soil health. but we need other elements within the soil as well. The cation-exchange capacity must be optimised through the use of lime and other soil treatments so those nutrients are available. The soil also needs to have the correct flocculation status, so that nutrients and roots can travel through it and drainage is optimised.

It is easy to define what productive, healthy soil is, but for some of the objectives in the Bill we need less than optimal soil health status. For example, all farmers agree that the most optimal way to enhance soil health is to have drainage schemes in place, but we have other agri-environmental schemes to try to prevent flooding, such as flood plains and areas of reed beds. Innovative schemes are happening on the North Yorkshire moors above Pickering, where the soil health is not optimised because that land is flooded deliberately to enable the delivery of those schemes.

Similarly, the North Yorkshire moors are a valuable habitat. The land is moor land because the soil is particularly acid and the soil health is bad—bad for growing most things apart from heather. Measures that could be put in place to enhance soil health there could actually act against enhancing that particular environment. We need to look at how we help farmers to manage their farms across the board. Some of their land may well be managed in a way that optimises soil health and production, but elsewhere soil health should deliberately not be enhanced, to allow certain species and habitats to develop precisely because that soil is flooded, acidified or not optimised for production.

[Jenny Chapman (Darlington) (Lab)]

I observe that the amendment asks that health soil be included in a list of things to which the Secretary of State “may” give financial assistance, not “must”. The right hon. Gentleman would not need to worry so much if he accepted the amendment.

[Mr Goodwill]

Yes, but we have recorded that it is the policy of the hon. Lady’s party to put “must” in the Bill, which will no doubt be introduced in the Lords.

[Jenny Chapman]

The right hon. Gentleman needs to make his mind up.

[Mr Goodwill]

The point I am trying to make is that it is very difficult to define enhanced soil health. Unlike animal health, where it is very easy to see whether an animal is healthy or not, there are a number of objectives, for example, looking at organic matter in the soil and the use of slurries.

Although many would wish to take measures to improve the organic matter in soils, there are downsides, particularly looking at nitrates. The Environmental Audit Committee, on which I sit, looked at nitrates in water and soils. Many of the problems with high levels of nitrates, which can lead to eutrophication in watercourses and the sea, in some cases, are due to high nutrient and nitrate levels being applied to the soil, which can be associated with organic fertilisers. My view is that this is an unnecessary amendment.

Soil health is best left to farmers. If we can create the situation where farmers manage their farms correctly, they will enhance soil health in those areas where they wish to maximise production but they might deliberately degrade soil health in order to encourage species that thrive in waterlogged, acidic and other soils. Although I can understand the motives behind the amendment, I do not believe it would achieve the intended objectives.

--- Later in debate ---

There is a multitude of interventions that we can support under subsection (1)(d), and I do not believe that the additional words add anything other than to the length of the sentence.

[Jenny Chapman]

I am not completely convinced by the Minister’s response. Mitigating is about lessening the impact of climate change. It is not about preventing it. We are trying to reduce emissions and the impact on climate change of agriculture and horticulture. They are different things. It is not true that the only difference is the length of the sentence.

[George Eustice]

On the terminology, we are not talking about mitigating the consequences of climate change. The subsection is very clearly about mitigating climate change itself. Any action that is taken to reduce carbon emissions and the emission of other greenhouse gases—ammonia is a very important one in agriculture—would be mitigating climate change. The subsection also includes the phrase “adapting to climate change” in recognition of the fact that, as Gilles Deprez pointed out in the evidence session, we are already living with the consequences. For instance, we recognise that we tend to have more floods, so we may need schemes to manage the implications of that. “Mitigating climate change” means what it says. It can include any actions that reduce greenhouse gas emissions.

[Jenny Chapman]

That is not right. Mitigating does not mean that. It means to lessen the severity or the impact of something. What the Minister is doing in the clause is very different to what we seek to achieve. The definition of “mitigating” matters.
