Which granular applicator provides the most precise placement when uniform distribution is required?

• A. Rotary spreader
• B. Drop spreader
• C. Broadcast spreader
• D. Pneumatic spreader

Answer: (B)

The key idea here is precision of placement when applying granular materials. A drop spreader releases granules straight downward from the outlet, creating a narrow, consistent band directly beneath the spreader. This setup gives the most exact placement and uniform coverage along that strip, which is ideal when you need controlled distribution and minimal drift around edges or obstacles. In contrast, a rotary spreader throws granules outward in a wide, spinning pattern, leading to broader coverage but less control over exact placement. A broadcast spreader disperses granules in a wide arc, achieving quick, large-area coverage but with more variability and susceptibility to wind. A pneumatic spreader uses airflow to push granules out, which can produce uneven distribution depending on air flow and settings. So, for the goal of the most precise placement with uniform distribution, the drop spreader is the best choice.
