Which turf cultivation practice removes soil cores with hollow tines to relieve soil compaction and improve distribution of pesticides?

• A. Core-aerification
• B. Coverage
• C. Cross-resistance
• D. Cultural Control

Answer: (A)

Core-aerification uses hollow-tined equipment to remove soil cores, breaking up compacted turf soil. This creates extra pore space and channels for air, water, and chemical movement, so pesticides can infiltrate and distribute more evenly through the rootzone. The result is improved pesticide distribution where soil compaction would otherwise hinder spread. The other terms don’t describe this soil-cultivation practice: coverage refers to how well a chemical is spread, cross-resistance is about pests becoming resistant to multiple pesticides, and cultural control is a broad pest-management approach not specifically about removing soil cores.
