Variable-rate technology: the right dose for every square metre
Most fields are not uniform. Flat-rate spraying wastes product where the crop is healthy and under-treats the places that need it most. With variable-rate technology (VRT), a prescription map tells the machine how much to apply as it moves.
OREL Vision builds that prescription from your own survey data and delivers it in the format your drone or sprayer controller reads.

What VRT can be used for
Variable-rate spraying
Pesticide, fungicide and herbicide doses matched to infestation and canopy density.
Variable-rate fertiliser
More nutrient where crop is weak and soil is poor, less where it is already strong.
Seeding and gap filling
Identify stand gaps early and target re-sowing.
Defoliants and growth regulators
Even crop termination and canopy control across zones.
How a VRT job runs
Survey
Multispectral or RGB flight over the target fields.
Zone
Maps are split into management zones with agronomist input.
Prescribe
A dose is set for each zone based on product and crop stage.
Apply
The prescription file loads into the application drone or sprayer.
Review
Application logs and a follow-up map show the result.
Benefits depend on crop, field variability and product. We set targets with you before the first flight and measure against them.
