Which of the following factors does NOT influence calibration of sprayers?

Calibration of sprayers is an essential process to ensure that the correct amount of pesticide or fertilizer is applied to a given area. Several key factors influence this calibration, including ground speed, tank capacity, and output rate.

Ground speed affects the calibration because it determines how quickly the sprayer moves over the area being treated. A faster ground speed means that the product is applied over a larger area in a shorter amount of time, which can lead to under-application if not accounted for.

Tank capacity is also a factor in calibration. It dictates how much product is available for application, which affects how the sprayer can be used in relation to the area being treated. Understanding the tank capacity helps operators to plan applications and avoid running out of product mid-route.

Output rate is critical for calibration since it indicates how much product is being dispensed per unit of area. This rate needs to match the intended application rate to ensure efficacy and safety.

Humidity, while it contributes to the overall environmental conditions at the time of application, does not directly affect the sprayer calibration. Instead, humidity may influence the behavior of pesticides during application and affect drying times or volatility, but it does not change the mechanical measurements or settings related to how the sprayer delivers the product.
