Application rate per hectare

This metric is fundamental for sprayer calibration to ensure that the active ingredient is applied uniformly across the target area. An accurate application rate prevents under-dosing, which leads to poor pest control, and over-dosing, which can damage crops or increase environmental impact.

The rate is controlled by selecting appropriate nozzle sizes, adjusting tractor speed, and setting the correct pump pressure. Agronomists must adjust these settings based on canopy density; dense crops typically require a higher volume of water to ensure thorough penetration of the foliage.

Common mistakes include failing to calibrate the equipment before the season, using worn-out nozzles that deliver uneven spray patterns, and neglecting the effects of wind and evaporation. Proper attention to these factors ensures the best possible return on investment for crop protection products.
