When are fertilizer applications prohibited?

• A. When heavy rain is forecast.
• B. During drought conditions.
• C. On very windy days.
• D. During the first hour after sunrise.

Answer: (A)

Applying fertilizer when heavy rain is forecast is prohibited because rain can wash nutrients away from the target area, leading to runoff into streams, rivers, and groundwater. This wastes fertilizer and can pollute water and harm aquatic life. The forecast of heavy rainfall creates a high risk that nutrients won’t stay in the treated zone or be absorbed by plants, so postponing is the responsible choice. Other conditions impact effectiveness and drift risk but aren’t universal prohibitions. Drought reduces nutrient uptake and can waste fertilizer, but isn’t always a blanket ban. Very windy days raise the chance of drift to non-target areas and may be restricted by label directions, but rules vary. The first hour after sunrise isn’t a standard automatic prohibition; timing guidance focuses more on moisture, wind, and rainfall potential.
