PRF4: Mechanical robotic weeding

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’ll be paid 

£150 per hectare (ha) per year

Action’s aim 

This action’s aim is that mechanical robotic weeding technology is used to control weeds, so there’s minimal use of herbicides.

The purpose of this is to:

  • improve productivity, water and soil quality
  • increase biodiversity
  • support an integrated pest management approach

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 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

Eligibility of protected land

Land or features with protection Eligibility
Sites of special scientific interest (SSSIs) Eligible – you must get SSSI consent before you do this action (read section 5.5 ‘Land that’s a site of special scientific interest (SSSI)’)
Historic and archaeological features Eligible – you must get a HEFER before you do this action (read section 5.6 ‘Land with historic or archaeological features’)

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

You must control weeds on land entered into this action using a mechanical robotic weeder that:

  • weeds between and within the rows of one crop
  • has camera or GPS-guided hoes which physically remove the weeds from the ground

You must do this action on one crop from when it’s sown until it’s harvested.

For the purposes of this action, a crop includes:

  • combinable crops, such as cereals and oilseed rape
  • root crops
  • field vegetables and salad crops
  • soft fruit crops which do not occupy the land for 5 years or more and provide repeated harvests (also known as ‘permanent crops’)

You can choose which crop to do this action on, but it must be a ‘cash crop’. This means it’s a crop grown to be harvested for commercial use.

You can apply residual herbicides to the crop before the sown crop plants or weeds emerge (‘pre-emergence’).

‘Residual’ herbicides are long-lasting selective herbicides which control certain weed species without harming the crop.

You must not use any other herbicides on the crop from when it’s sown until it’s harvested.

When to do it 

You must do this action on at least one crop that’s sown during each year of this action’s 3-year duration. You can harvest it in a subsequent year of this action’s duration if you sow the next crop for this action in the same year.

This means you must do this action on a crop that’s sown during:

  • the first year of this action’s duration – you can harvest it in the second year of this action’s duration
  • the second year of this action’s duration – you can harvest it in the third year of this action’s duration
  • the third year of this action’s duration – you must do this action until you harvest that crop or this action’s end date, whichever is earlier

If you’re already growing a crop on the land entered into this action when this action starts, you must do this action on a crop that’s sown within 12 months of this action’s start date.

How to do it  

You must follow this action’s requirements – these are identified by a ‘must.’

Advice to help you do this action will be published before applications are fully launched from summer 2024. It will not be 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:

  • data from the tractor’s job recording system identifying the mechanical robotic weeder, the date and areas weeded
  • field operations at a land parcel level, including the land parcel reference number and the dates the crop was sown and harvested
  • contractor’s invoice if you use a contractor to do this action

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.
