Rotary spreaders compared to a drop granular spreader tend to create more drift.

• A. Less drift
• B. About the same drift
• C. No drift
• D. More drift

Answer: (D)

Focus is on how the application method influences drift. Rotary spreaders throw granules outward as the spreader spins and release material from a higher height, creating a broad, fan-shaped distribution. That combination means more of the product can be carried by wind and deposited off the target area. In contrast, a drop granular spreader places material directly on the ground below the hopper at a low height, producing a much narrower, more targeted pattern with less opportunity for wind to push granules away. Because the rotary spreader inherently spreads material farther from the intended target and from a higher release point, it tends to result in more drift than a drop spreader. Keep in mind that wind speed, nozzle height, and calibration also affect drift, but the general tendency is greater drift with rotary spreaders.
