SOH3: Multi-species summer-sown cover crop

What you must do to get paid for this action and advice on how to do it.

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鈥檒l be paid

拢163 per hectare (ha) per year

Action鈥檚 aim

This action鈥檚 aim is that there鈥檚 a well-established summer-sown multi-species cover crop which is present between harvesting a cash crop, until either:

  • the next cash crop is sown
  • a winter cover crop is sown

The purpose of this is to:

  • protect the soil surface
  • provide root growth that benefits soil structure, supports soil biology and minimises nutrient leaching, soil erosion and runoff
  • add organic matter

Where you can do this action

You can do this action on agricultural land located below the moorland line that鈥檚:

  • an eligible land type (as defined in section 5.1 鈥楨ligible land types for SFI鈥� in the SFI 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
Arable land used to grow crops, excluding temporary grassland Arable land Land use codes for arable crops or leguminous and nitrogen-fixing crops
Arable land lying fallow Arable land FA01
Horticultural permanent crops Permanent crops TC01

Eligibility of protected land

Protected land Eligibility
Sites of special scientific interest (SSSIs) Eligible 鈥� you must get SSSI consent before you do this action (read section 10.3 鈥�SSSI 肠辞苍蝉别苍迟鈥� in the SFI scheme information to find out how to do this)
Historic and archaeological features Eligible 鈥� you must get a SFI HEFER before you do this action (read section 5.6鈥楲and with historic or archaeological features鈥� 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鈥檚 duration
  • do it at the same location each year of this action鈥檚 duration

What to do

You must establish a multi-species cover crop mix during the summer months (usually between June and August) which will not be harvested as a cash crop.

A 鈥榗ash crop鈥� means a crop grown to be harvested for commercial use.

You must use a rapid growing seed mix that contains at least 4 species. This must include 2 species from two or more of the following plant families:

  • brassicas
  • legumes
  • cereals and grasses, with grasses making up no more than 25% of the total mix by weight
  • herbs

The seed mix must not contain:

  • Japanese reed millet
  • maize
  • miscanthus or reed canary grass
  • sorghum (all varieties)
  • artichokes
  • sweet fennel

You must avoid growing deep rooted species on any area within a land parcel with historic or archaeological features identified in your SFI HEFER. Read section 5.6鈥楲and with historic or archaeological features鈥� in the SFI scheme information for more details.鈥�

You must maintain the multi-species cover crop in a way, and for a period of time, that can reasonably be expected to achieve this action鈥檚 aim.

For the purposes of this action鈥檚 aim, the cover crop will be well-established if there鈥檚:

  • leafy vegetation that鈥檚 sufficiently well grown to protect the soil surface
  • minimal bare soil

You must not do the following on the well-established cover crop:

  • cut it or graze it with livestock (other than when destroying the cover crop)
  • mechanically apply any fertilisers or manures
  • destroy it more than 2 weeks before you intend to establish the next main crop

When you destroy the cover crop, you should try to minimise risks such as compaction, poaching, soil runoff or erosion.

If something happens which means you cannot complete this action, you must tell the Rural Payments Agency about this in writing as soon as possible. For example, if there鈥檚 prolonged adverse weather. Read section 13.2: 鈥榃hat you must do if you cannot comply with your agreement鈥� in the SFI scheme information to find out how to do this.

You must not use the following to meet this action:

  • a multi-species temporary grass ley, such as a mix of grass and clover, that is being used for grazing
  • a multi-species crop which you intend to harvest as a cash crop, such as a mix of wheat and clover

You can only use an existing multi-species cover crop to meet this action鈥檚 requirements if you overseed it. This includes a cover crop already paid for under an environmental land management scheme action, such as SOH2 (multi-species spring-sown cover crop).

When to do it

You must do this action each year of its 3-year duration.

If this action鈥檚 start date means it鈥檚 too late for you to do this action, you must start doing it within 12 months of the action鈥檚 start date.

In the final year of this action鈥檚 duration, you must do this action until the next main crop is sown, or this action鈥檚 end date, whichever is earlier.

How to do it

It鈥檚 up to you how you do this action, as long as you:

  • follow this action鈥檚 requirements 鈥� these are identified by a 鈥榤ust鈥�
  • do the action in a way that could reasonably be expected to achieve this action鈥檚 aim

You may find it helpful to read the 鈥榓dvice to help you do this action鈥�, but it鈥檚 not part of this action鈥檚 requirements.

Evidence to keep

You must keep evidence to show what you鈥檝e done to complete this action, such as:

  • field operations at a land parcel level and associated invoices, including details of the seed mix used
  • photographs and other documentation

If it鈥檚 not clear that you鈥檝e 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鈥檙e done at a different time of year to this action. For example, winter cover followed by a summer companion crop. Read 鈥榃hat to do鈥� and 鈥榃hen to do it鈥� 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鈥檚 not part of this action鈥檚 requirements.

Growing cover crops on land used for permanent horticultural crops

If you鈥檙e doing this action on land used to grow permanent horticultural crops, you can plant cover crops:

  • around fruit or nut trees
  • between rows of trees

Choosing a seed mix

This action explains the minimum requirement for species in the seed mix (under 鈥榃hat to do鈥�). Table 1 shows examples of what you could use.

Table 1: Species you could use

Plant family Species
Brassicas Yellow mustard, brown mustard, oil radish, tillage radish, stubble turnip, kale
Legumes Common vetch, hairy vetch, red clover, white clover, alsike clover, sweet clover, crimson clover, lucerne, black meddick, peas and beans
Cereals or grasses Italian ryegrass, festulolium, black oats, forage rye, barley, winter triticale
Herbs Phacelia, buckwheat, linseed

Choosing a varied mix (with multiple species from different plant families and with different characteristics) will normally bring greater benefits to your soil.

If you鈥檙e in an area with a shorter growing season, you may need to choose plants that germinate and grow in cooler weather.

Your seed supplier can help you choose a seed mix that鈥檚 the best match for your land and local conditions.

You may find it helpful to read the Agriculture and Horticulture Development Board (AHDB) .

Where to establish the cover crop

When you establish the cover crop, by law you cannot cultivate or apply fertilisers or pesticides to land within 2m of the centre of a hedgerow. Read the guidance on Hedgerow management rules: buffer strips to understand how these rules apply to you.

How to sow the cover crop聽

Your seed supplier can advise you on an overall sowing rate for the seed mix you choose.

You can drill or broadcast the seed mix. Drilling seeds is usually more reliable and gives a higher germination success than broadcasting. However, broadcasting is cheaper.

After you have sown the seed mix you can roll the seeds if the soil is dry enough. This can help to:

  • improve seed-to-soil contact
  • retain moisture
  • reduce the risk of slug damage

Maintaining the cover crop

The cover crop will usually provide the most benefits to your soil if you maintain it for a period of at least around 8 consecutive weeks. However, this may differ depending on your crop rotation and geographical location.

How to destroy the cover crop

If you鈥檙e destroying the multi-species cover crop, you can choose what method you use.

Improving soil health

You can increase the benefits to soil of cover crops by combining them with:

  • minimum tillage or no tillage (鈥榥o-till鈥�) systems 鈥� you may want to consider SOH1: No-till farming
  • organic farming 鈥� there are several SFI actions which support this (search 鈥榦rganic鈥� in the 鈥楩ind funding for land or farms鈥� tool)
