What is it?
The Small Robot Company Harry is the fertiliser application robot in the Tom-Dick-Harry system. It uses Tom's per-plant crop map to deliver precisely calibrated micro-doses of liquid fertiliser directly to the root zone of individual plants that have been identified as needing nutrient input.
Who is it for?
Arable farmers targeting nitrogen use efficiency and fertiliser cost reduction. Farms operating under nitrate vulnerable zone restrictions or environmental land management schemes with input reduction requirements. Precision agronomy operations seeking to validate per-plant crop nutrition as an alternative to broadcast spreading economics.
Key specs
- Function: Per-plant precision fertiliser micro-dosing
- Application method: Liquid fertiliser direct to root zone
- Navigation: Tom-generated plant map guided
- Reduction potential: Up to 95% fertiliser reduction vs broadcast
- Power: Electric
- Integration: Requires Tom mapping data
- Origin: UK
Economic case
Nitrogen fertiliser represents one of the highest variable costs in arable farming. If Harry's per-plant targeting can deliver comparable yield outcomes with 50–95% less fertiliser, the input cost saving creates a direct economic justification alongside the environmental benefit of reduced nitrate leaching.
Limitations
- Requires Tom robot data
- Per-plant liquid application throughput limited by robot speed
- Commercial scale deployment still maturing
- Liquid fertiliser system requires on-board tank management
FAQ
How much fertiliser can Harry save versus broadcast spreading?
Small Robot Company's per-plant approach targets up to 95% reduction in fertiliser application versus broadcast spreading by applying nutrients only to plants that Tom's map identifies as requiring input, at precisely the dose needed.
What type of fertiliser does Harry apply?
Harry applies liquid fertiliser directly to the root zone of individual plants. The specific fertiliser formulations compatible with the Harry system should be confirmed with Small Robot Company during the sales process.
Does Harry need Tom to operate?
Yes. Harry relies on Tom's per-plant crop map to identify which plants require fertiliser and at what dose. Harry cannot operate as a standalone precision fertiliser robot without Tom's mapping data.
Is Harry commercially available?
Harry's commercial availability and deployment scale should be confirmed directly with Small Robot Company, as the platform has been in staged commercial rollout with arable farm partners.
