Full details
This is a Sustainable Farming Incentive 2026 (SFI26) action. Read the SFI26 scheme information to understand what you’re required to do under an SFI26 agreement and how to apply. Select ‘See all updates’ at the start of this page to find out how this action has changed for SFI26 compared with SFI24. For SFI24 actions, read the SFI24 agreement holder’s information. Duration 3 years How much you’ll be paid £515 per hectare (ha) per year – calculate the hectarage by: • measuring the length of the buffer strip in metres (m) • multiplying that length by the relevant width (6m to 12m) to give the area in m2 • dividing that area by 10,000 to convert it into ha Action’s aim This action’s aim is that there’s a grass buffer strip: • with an intact grass sward throughout the year • without tracks, compacted areas or poaching The purpose of this is to: • protect existing landscape and heritage features • provide habitat for wildlife • prevent pollutants, such as sediment and nutrients, from being carried in surface water runoff, if located next to a watercourse • support an integrated pest management approach, if located close to cropped areas, which can help to reduce costs and improve farm resilience 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 You can also do this action on eligible land that’s in a flood risk area. Check the flood risk map and read the guidance on how to use the flood risk map. This can include land which may have flood risk management works carried out on it by a flood risk management authority, such as Internal Drainage Boards. Eligible land Eligible land type Eligible land cover Compatible land use code Arable land used to grow crops Arable land Land use codes for arable crops or leguminous and nitrogen-fixing crops Temporary grassland Arable land TG01 Arable land lying fallow Arable land FA01 Permanent crops – horticultural Permanent crops TC01 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: Eligible – you must get an SFI HEFER before you do this action (read section 5.3 ’Land with historic or archaeological features’ in the SFI26 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. 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 static. This means you must do it at the same location each year of this action’s duration. What to do You must establish and maintain a grass strip on land entered into this action that’s: • at least 4m to 12m wide (on average in each land parcel) – it can be more than 12m wide, but you’ll only be paid for the 12m width. • on the edge of arable and horticultural land The grass strip must buffer an existing landscape feature, or certain heritage features, such as: • hedgerows • stone walls • woodland • ditches, rivers and streams • upstanding historic and archaeological features, such as earthworks, in-field structures or buildings You can also locate the grass buffer strip next to: • trackways that channel run-off water directly into a watercourse • fence lines that form links between areas of wildlife habitat You must make sure the grass strip is in addition to any regulatory requirements relating to buffer strips. Once the grass strip is established, you must manage it in a way that can reasonably be expected to achieve this action’s aim. During late summer, after the bird breeding season, you must cut part of the grass strip’s width next to the edge of the crop or fallow land. You must do this along as much of the strip’s length as possible. This is to provide some shorter vegetation and a range of habitat types. Flood risk management authorities, such as Internal Drainage Boards, may carry out flood risk management works on the grass buffer strip if it’s located in a flood risk area. Check the flood risk map and read the guidance on how to use the flood risk map. If this happens, you must repair any damage to the grass buffer strip as soon as reasonably practicable. You must not do any of the following on the grass buffer strip once it’s established: • use it for regular vehicular access, turning or storage (for example, storing bales or machinery) • apply fertilisers or manures • apply pesticides, except for herbicides to weed wipe or spot treat to control injurious weeds, invasive non-native species, nettles or bracken You can maintain an existing grass buffer strip to get paid for this action if it: • meet this action’s requirements • are not already being paid for under another environmental land management scheme option, such as CS option SW1 (4m to 6m buffer strip on cultivated land) When to do it You must: • establish the grass buffer strip within the first 12 months of this action’s duration • maintain the same area of grass buffer strip in each subsequent year of this action’s duration 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. 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.

How and where to establish the grass buffer strip You can establish the grass buffer strip by either: • sowing a seed mix • using natural regeneration This action explains: • which landscape features the grass strip is required to buffer (under ‘What to do’) • that the 4m to 12m wide grass strip must be in addition to any regulatory requirements relating to buffer strips You are required by law to have 2m buffer strips next to hedgerows. This means you need to establish the 4m to 12m wide grass strip at least 2m from the centre of a hedgerow. Read the guidance on Hedgerow management rules: buffer strips to understand how these rules apply to you. Sowing a seed mix Sowing a seed mix can establish the grass buffer more quickly, which can reduce the risk of soil erosion. You can choose a seed mix that contains native grass species, such as: • timothy • cocksfoot • crested dog’s tail • red fescue • smooth-stalked meadow grass It can help the seeds to germinate if they’re sown into a seedbed that’s: • firm, consolidated, fine, level and weed free • moist, which will usually be the case in the autumn – you can sow in the spring, but you may need to increase the sowing rate, depending on weather and soil type You can either: • broadcast the seeds onto the surface of the seedbed to help germination • shallow-drill the seeds up to a depth of 1 centimetre (cm). Small seeds may struggle to germinate when sown deeper than 1cm If the soil is dry enough, rolling after you have sown the seeds can: • improve seed-to-soil contact • keep moisture • reduce the risk of slug damage Your seed supplier can: • help you choose a seed mix that’s the best match for your land and local conditions • advise you on an overall sowing rate for the seed mix you choose Using natural regeneration Using natural regeneration means the grasses in the buffer strip are local to your area. It can take longer to establish the buffer strip, but it may cost less. To encourage the seeds that are already in the soil to germinate, you can cultivate the soil between spring and late summer. Maintaining the established grass buffer strip Once the grass buffer strip is established, this action requires you to maintain it by managing it in a way that can reasonably be expected to achieve this action’s aim. Cutting part of the grass buffer strip’s width This action requires you to cut part of the grass strip’s width next to the edge of the crop or fallow land during late summer (after the bird breeding season). It’s up to you how much of the buffer strip’s width you cut. Cutting up to half of the width from the edge of the crop or fallow land can help to provide: • short grass for birds to forage in (such as grey partridge chicks) • mid-length grass for species like brown hares • long, rarely cut tussocky grass to give shelter and nesting places for birds and invertebrates You can stagger cutting, so you do not cut all your buffer strips at the same time. during late summer. This will usually mean there’s always habitat available for invertebrates and small mammals. Where possible, remove the cut vegetation to limit weeds and reduce the risk of it smothering the flower species. If this is impractical, you can finely chop the vegetation to spread it as thinly as possible. Controlling weeds You may need to control weeds when they appear. To control weeds like docks, nettles, thistles and common ragwort, you can cut the affected area, providing there’s still an intact grass sward. This action also allows you to use herbicides to weed wipe or spot treat weeds.
