Which item must be documented by the applicator regarding fertilizer applied on the golf course?

• A. The specific rate and composition of fertilizer applied
• B. The weather conditions at application
• C. The time of day of application
• D. The brand of the pesticide used

Answer: (A)

Documenting the exact rate and the composition of the fertilizer applied is what regulations require for fertilizer on a golf course. Recording the rate shows exactly how much product was put down over a given area, and the composition (the nutrient makeup like N-P-K and any micronutrients) identifies what nutrients were delivered. Together, these details ensure the application follows label directions, supports proper nutrient management, and provides a clear record for regulatory review or environmental protection.

Weather conditions, time of day, and the brand of any pesticide used aren’t mandated elements for fertilizer records. Weather data can be useful for broader operations or pest management decisions, but it isn’t the required item for fertilizer documentation. Time of day isn’t typically a recorded requirement for fertilizer unless a specific program dictates it, and the pesticide brand isn’t relevant to fertilizer recordkeeping.
