Weed Mapping: A Smarter Path to SFI Funding
​
Unlock Sustainable Farming Incentive (SFI) PRF2 Grant


Weed Mapping is revolutionising herbicide application by introducing precision technology into farming practices. With this grant, you can reduce herbicide usage, protect biodiversity, and ensure healthier soil and water—all while receiving financial support to future-proof your farm.

​

Grant Details at a Glance:

  • Duration: 3 years

  • Payment: £43 per hectare annually

  • Purpose: Harness cutting-edge camera or remote sensing technology to target herbicide application with pinpoint accuracy. This reduces the amount of herbicide needed, supports biodiversity, and protects natural resources.

 

Who Can Apply?

Farmers managing arable and grassland areas below the moorland line where systemic herbicides are used for weed control are eligible. If that’s you, this grant offers both environmental and financial benefits.

Step 1: Field Assessment & Flight Planning (max 140 ha/day)

We begin by assessing your location and defining the survey area using satellite imagery and field boundaries.
Flight paths are optimised for efficient coverage and data accuracy depending on the survey type

Step 2: Survey Execution

  • Flight Speed: ~10 mph

  • Flight Height: 70 meters

  • Coverage: ~0.3 hectares per minute

  • Details: Requires high-resolution images to identify weeds. Lower altitude improves detail but reduces coverage.


Step 3: Data Upload & Processing for

The larger the Ha area, the longer the upload and data processing takes.  Whilst the process is largely automated it does require our judgment at certain key stages.  These are typical times for upload and processing a 100 Ha: -

  • (4-6 hours) Import imagery and create an Orthomosaic. Use indices such as ExG or GNDVI to differentiate weeds from crops.

  • (1-2 hours) Use the Zonation tool for semi-automatic weed detection and manual classification.

  • (1 hour) Export Weed Density Maps for precision herbicide application maps.


Step 4: Delivery of Results

Output/Report

  • Weed Density Maps: Visual maps indicating weed presence and density within the field.

  • Orthomosaic: Detailed field imagery highlighting weed patches.

  • Zonation Reports: Segmented field maps to assist with site-specific herbicide application.

File Type Options

  • Orthomosaic & Weed Maps: GeoTIFF (.tif), PDF, PNG

  • Zonation & Prescription Files: SHP, ISOXML, CSV
