Which factor does NOT contribute to drift when applying pesticides?

Droplet size
Wind speed
Soil moisture
Application height

The correct answer is: Soil moisture

Soil moisture does not contribute to drift during pesticide application because drift primarily occurs through airborne particles that can be influenced by environmental conditions during the spraying process. Drift is mainly affected by factors such as droplet size, wind speed, and application height. Droplet size is crucial because smaller droplets are more susceptible to being carried away by the wind. Wind speed can significantly increase drift potential, as stronger winds can transport fine droplets over greater distances. Application height also plays a role; the higher the sprayer is from the target area, the further droplets may drift due to wind currents. Therefore, unlike the other mentioned factors, soil moisture pertains more to the condition of the ground and does not directly affect the dispersion of pesticide particles into the air.
