A 10' Ring of Responsibility should be extended when using which method of fertilizing?

• A. When using liquid fertilizer
• B. When using organic compost
• C. When using foliar spray
• D. When using granular fertilizer without a shield

Answer: (D)

The key idea is containment and drift control when applying fertilizer. Granular fertilizer can scatter, bounce, or drift with wind, especially if there’s no shield on the spreader. Extending the Ring of Responsibility ensures stray granules stay within the intended area and don’t reach nearby plants, sidewalks, or runoff pathways. Other methods don’t pose the same exact drift risk from broadcast granules: liquids are usually applied with directed spray and containment, compost is incorporated into the soil, and foliar sprays target leaves with controlled droplets. So, when using granular fertilizer without a shield, widening the ring is the best practice to keep the product where it’s needed and minimize unintended damage.
