However, this is not the case for variable rate nitrogen.

Therefore, the PRF1 action stipulates that when remote sensing is used to calculate the nitrogen requirement, it must be carried out no more than 14 days prior to application.
The above-average rainfall and heavy cloud cover during spring 2024 meant that those relying on optical imagery from the Sentinel-2 satellites struggled to obtain images of sufficient quality to meet the PRF1 action. Around 80% of the imagery produced was rejected.

It provides high accuracy through full-spectrum optical and infrared imagery, including NDVI and GCVI from synthetic-aperture radar (SAR) – see Figure 4. Unlike Sentinel-2, SAR imagery does not require a clean line of sight and is unaffected by cloud cover.

Unlike other ‘cloud-free’ solutions, ClearSky does not rely on sporadic clear optical imagery for calibration. This provides greater confidence in the data supplied to customers.
Analysis by Agrii, covering 900,000ha, revealed that the Sentinel-2 system produced an average of 13.3 clear images per farm in 2023. In comparison, the ClearSky platform increased this number to 60.8, which improves even further when including cloud-free images captured by Sentinel-2.
Adopting technology that enhances the performance and resilience of agriculture is a key objective of the SFI. Demonstrating compliance with its actions goes beyond a simple tick-box exercise. Participants are expected to show they are fulfilling the required actions on demand. In some cases, this means providing a report; in others, it requires producing the actual data used to fulfil the task. ClearSky ensures that variable rate applications align with crop needs while making it easier to demonstrate compliance with the PRF1 action.
