What should be maintained once the equipment is calibrated?

Maintaining pump pressure, nozzle size, and ground speed once the equipment is calibrated is crucial for ensuring the effectiveness and accuracy of herbicide application. Calibration is the process of adjusting the equipment so that it delivers the correct amount of herbicide based on specific parameters.

Pump pressure directly influences the flow rate and dispersion pattern of the herbicide. If the pressure fluctuates or is not maintained, it can lead to either under-application or over-application of the herbicide, both of which can have negative effects on weed control and the surrounding environment.

Nozzle size affects the droplet size and pattern of the herbicide being applied. Different nozzle sizes can create varying spray characteristics, which can impact coverage and the ability to reach the intended target areas. Maintaining the correct nozzle size ensures that the herbicide is applied in the manner it was calibrated for.

Ground speed is also essential because it determines how quickly the equipment is moving while applying the herbicide. If the speed varies from what was used during calibration, it could result in unequal application rates, leading to ineffective control of weeds or potential damage to non-target plants.

Focusing on these three factors ensures that the calibration remains valid throughout the application process, which is vital for achieving consistent and effective herb
