The fertilization process should be guided by soil analyses to determine the:

• A. Desired amount
• B. Color of fertilizer
• C. Time of day for application
• D. Brand of fertilizer

Answer: (A)

Soil analyses guide how much fertilizer is needed. A soil test shows what nutrients are already present and what the turf requires to reach target levels, so the recommended fertilizer rate is adjusted to supply precisely what’s missing. This helps prevent under-fertilization and reduces waste and environmental impact.

The color of fertilizer, the time of day you apply it, or the brand don’t reveal the turf’s actual nutrient needs. Color is just packaging, time of day relates to conditions for applying the product, and brand varies in formulation; none of these determine the required amount the soil needs based on analysis.
