Which short-term action is used to correct iron deficiency in turf?

• A. Lowering soil pH.
• B. Applying an iron-containing fertilizer.
• C. Increasing phosphorus only.
• D. Increasing potassium.

Answer: (B)

When turf shows iron deficiency, the quickest fix is to supply iron directly to the plant. An iron-containing fertilizer delivers iron where it’s needed, often producing visible green-up within days to a couple of weeks. This can be through soil applications or foliar sprays, and chelated forms are especially effective if soil pH reduces iron availability.

Lowering soil pH can improve iron availability, but it’s a slower adjustment that may require time and ongoing management, not an immediate correction. Increasing phosphorus or potassium doesn’t address the iron deficiency itself, so they won’t provide the rapid remedy the turf needs.
