A system and method combines photometric crop surveillance with a ground-mounted directional, variable-flow sprayer that compensates for wind to enable selective, per-patch application of water, fertilizer, or crop-protection products. Photometric imagery is processed to produce georeferenced treatment targets and recommended application quantities. Wind-field estimations and local wind-sensing are used to compute aim offsets, droplet size, and flow / dwell and shielding parameters that compensate for advection and turbulence. The system commands a sprayer with aimable nozzles and proportional flow control with per-target, wind-compensated parameters to selectively treat sub-areas at different doses, while minimizing drift. Follow-up photometric verification and logged wind telemetry enable closed-loop learning of drift / advection models.

This value sequence is representative of that combination. In the future, if the same combination is used, it will be possible to identify it from the measured values without knowing the exact content of the mixture. In addition, continuous monitoring is a great help for crop protection professionals to accurately adjust additives. Through continuous monitoring, spraying can be safer in all aspects.
