This is an action in the Sustainable Farming Incentive (SFI) scheme: expanded offer for 2024. You must read the SFI scheme information to understand the scheme rules and how to apply.
Duration
3 years
How much you’ll be paid
£264 per hectare (ha) per year
Action’s aim
This action’s aim is that there’s a post-harvest stubble with some green cover over the autumn and winter months.
The purpose of this is to provide:
- a winter food source for seed-eating farmland birds
- foraging habitats for farmland wildlife
Where you can do this action
You can do this action on agricultural land located below the moorland line that’s:
Eligible land
- Eligible land type: Arable land used to grow cereals (not maize), oilseed rape or linseed
- Eligible land cover: Arable land
- Compatible land use code: Land use codes for arable crops
Eligibility of protected land
- Land or features with protection: Sites of special scientific interest (SSSIs)
- Eligibility: Eligible – you must get SSSI consent before you do this action (read section 10.3 ‘SSSI consent’ in the SFI scheme information to find out how to do this)
- Land or features with protection: Historic and archaeological features
- Eligibility: Eligible – you must get a SFI HEFER before you do this action (read section 5.6 ‘Land with historic or archaeological features’in the SFI scheme information to find out how to do this)
Available area you can enter into this action
Total or part of the available area in a land parcel.
Rotational or static action
This action is rotational or static. This means you can either:
- move its location for the second and third years of this action’s duration
- do it at the same location each year of this action’s duration
What to do
After harvest, you must:
- leave the stubble
- in each land parcel, establish a green overwinter cover crop on the stubble area (such as mustard or fodder radish) so it covers between approximately 10% to 50% of the area entered into this action
You must maintain the stubble area (including the green overwinter cover crop) for a period of time that can reasonably be expected to achieve this action’s aim. This will usually be until around mid-February.
You must not do the following on the stubble area (including the green overwinter cover crop):
- top or graze it
- apply any fertilisers, manures or lime
- cultivate it after harvest
When to do it
You must do this action each year of its 3-year duration.
If this action’s start date means it’s too late for you to do this action, you must start doing it within 12 months of the action’s start date.
In the final year of this action’s duration, you must do this action until around mid-February or this action’s end date, whichever is earlier.
How to do it
It’s up to you how you do this action, as long as you:
- follow this action’s requirements – these are identified by a ‘must’
- do the action in a way that could reasonably be expected to achieve this action’s aim
You may find it helpful to read the ‘advice to help you do this action’, but it’s not part of this action’s requirements.
Evidence to keep
For all the land entered into this action, you must keep:
- written evidence that it’s not at risk of soil erosion or surface runoff – you can use the soil management plan produced for CSAM1 or SAM1 to identify this
- a valid organic certificate and schedule for it – this must cover at least the full period of this action’s duration
You must also keep other evidence to show what you’ve done to complete this action, such as:
- field operations at a land parcel level and associated invoices
- photographs or other documentation
If it’s not clear that you’ve done this action in a way that could reasonably be expected to achieve its aim, we may ask for this evidence. You must supply the evidence if we ask for it.
Other actions or options you can do on the same area as this action
You can do the following actions or options on the same area in a land parcel as this action.
Some actions or options can only be done on the same area if they’re done at a different time of year to this action. For example, winter cover followed by a summer companion crop. Read ‘What to do’ and ‘When to do it’ to find out when this action must be done.

Advice to help you do this action
The following advice may help you to do this action, but it’s not part of this action’s requirements.
Choosing the right location
Overwinter stubbles are suitable for most soil types. Spring-sown crops (especially barley) can produce the best overwinter stubbles.
You can leave unmanaged overwinter stubbles across a whole field or a strip, if the land has been identified by you as not being at risk of soil erosion or surface runoff. You can do CSAM1 (assess soil, produce a soil management plan and test soil organic matter) to help you identify this.
You can have several areas of stubbles spread across your farm to link non-crop habitats (such as hedgerows, ponds and field margins). This can help wildlife to move between these habitats, especially in large fields (for example, over 20 hectares (ha)).
As this action requires you not to use post-harvest herbicides, try to locate the overwinter stubbles in fields which do not have a history of hard to control weeds. For example:
- black-grass
- couch
- docks
- sterile brome
- thistles
- wild oats
It’s usually best to locate strips of overwinter stubbles along south-facing boundaries. This will allow more beneficial weeds to grow, so more seeds are produced for birds to eat.
How to increase environmental benefits from the stubbles
To help to increase the environmental benefits provided by the overwinter stubbles, you can establish them:
- near to high-value habitats, such as hedgerows, scrub and woodland
- close to other seed-rich habitat
- in fields used by nesting lapwing or skylark
- close to areas of scrub which are suitable for nesting turtle dove
- on warm, sunny, south-facing headlands which support rare arable plants
You can provide the greatest range of habitat for wildlife by having different stubble heights across your farm. You can do this by lowering and raising the combine header.
Skylark and yellowhammer prefer shorter stubble, while other species like grey partridge shelter in taller vegetation.
After you harvest your crop, you can broadcast beneficial seed and nectar-producing plants (such as mustard and fodder radish) into the stubble.
Other ways to enhance stubbles for farm wildlife include:
- carrying out winter supplementary feeding for farmland birds next to areas of winter bird food
- managing your preceding crop with less inorganic nitrogen fertiliser and fewer herbicides
