Action’s aim
This action’s aim is that there are legumes growing from spring until early autumn.
The purpose of this is to:
-
manage nutrient efficiency
-
protect the soil surface
-
provide root growth that maintains soil structure, supports soil biology, and minimise nutrient leaching, soil erosion and runoff
-
support an integrated pest management approach if located close to cropped areas
Where you can do this action
You can do this action on agricultural land located below the moorland line that’s:
-
an eligible land type (as defined in section 5.1.1 ‘Eligible land types’ in the SFI26 scheme information)
-
registered with an eligible land cover on your digital maps
-
declared with a land use code which is compatible with the eligible land cover
Eligible land
| Eligible land type | Eligible land cover | Compatible land use code | |
|---|---|---|---|
| Temporary grassland | Arable land | TG01 | |
| Improved permanent grassland | Permanent grassland | PG01 |
Eligibility of protected land
Sites of special scientific interest (SSSIs): Eligible – you must:
-
give notice to Natural England to get SSSI consent before the Rural Payments Agency (RPA) offer you an SFI26 agreement
-
have received SSSI consent from Natural England before you do this action (read section 10.1 ‘SSSI consent’ in the SFI26 scheme information for more details)
Historic and archaeological features: Ineligible – you must not enter any area with an historic or archaeological feature into this action. This only affects the area where the feature is located in a land parcel. You can apply for this action on the remaining area in the land parcel if it’s eligible.
Available area you can enter into this action
Total or part of the available area in a land parcel. It’s your responsibility to check that the area you enter is eligible for this action.
You must do this action on the area entered into your SFI26 agreement. If something happens which means you cannot complete this action on some or all of the area, you must tell the RPA in writing as soon as possible. Read section 12.2 ‘What to do if you cannot comply with your agreement’ in the SFI26 scheme information to find out how to do this.
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
You must establish and maintain legumes on improved grassland entered into this action.
You can use one or more type of legume, such as:
-
red clover
-
white clover
-
alsike clover
-
sainfoin
-
lucerne
-
bird’s foot trefoil
You can establish the legumes by:
-
adding them to an existing grass sward
-
sowing a mix of grass and legumes
Once established, you must maintain the legumes. To do this, you must manage them in a way that can reasonably be expected to achieve this action’s aim.
You can maintain existing areas of legumes on improved grassland to get paid this action if they:
-
meet this action’s requirements
-
are not already being for under another environmental land management scheme option, such as CS option GS4 (legume and herb-rich swards)
When to do it
If you’re doing this action on the same area of land for this action’s 3-year duration, you must:
- establish the legumes within 12 months of this action’s start date
- maintain the area of legumes in each subsequent year of this action’s duration
If you’re rotating this action around your farm, each year of your SFI agreement you must do it for a period of time that could reasonably be expected to achieve this action’s aim.
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
You must keep 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.

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 a seed mix
Sainfoin, lucerne and alsike clover are more suited to grassland that you cut.
Your seed supplier can help you choose a seed mix that’s the best match for your land and local conditions.
Where to sow the seed mix
When you establish the legumes, by law you cannot cultivate or apply fertilisers or pesticides to land within 2 metres (m) of the centre of a hedgerow. Read the guidance on Hedgerow management rules: buffer strips to understand how these rules apply to you.
It can help to sow the seed mix where you want to reduce fertiliser use.
Nitrogen fixation from the legumes will reduce if the soil phosphate and pH are not at optimal levels.
Spreading the legume areas across the farm can help to provide a network of habitats for farmland wildlife.
How and when to sow the seed mix
Your seed supplier can advise you on an overall sowing rate for the seed mix you choose.
You can sow the seed mix shallowly into a firm seedbed or overseed into an established grass sward.
Sowing the seed mix in March or April can help germination.
Alternatively, you can sow after a silage cut, as the grassland is likely to be more open. You may get better results after the second silage cut (or late hay cut), as the regrowth is less vigorous.
Legumes sowed after August may not establish before the winter.
During establishment of the legumes
It’s advisable to keep livestock off the areas of legumes while the seedlings establish. This will prevent new grasses or legumes being grazed out.
Maintaining established legumes
Once the legumes are established, you can cut them or graze them with livestock providing you do it in a way that could reasonably be expected to achieve this action’s aim. This will help to reduce competition from existing plants.
You may find it helpful to read Farm Wildlife’s advice on rotational legume and herb-rich swards for livestock farming. This includes guidance on how you could manage the legume areas under ‘ongoing management’.
