Large droplet size is generally preferred for which type of fertilizer application?

Large droplet size is generally preferred for surface applications to avoid drift due to the physical properties of larger droplets. When fertilizer is applied using larger droplets, they are less likely to be picked up and carried away by wind, minimizing the risk of off-target movement. This is particularly important in agricultural environments where precision application is crucial to avoid contaminating nearby fields, water sources, or sensitive areas.

In addition, larger droplets tend to settle more quickly, ensuring that the fertilizer lands directly on the intended surface rather than being aerosolized. This characteristic allows for a more accurate application rate, limiting wastage and enhancing the efficiency of the fertilizer being used. This is especially critical in situations where there is an increased risk of drift, such as during windy conditions.

In contrast, smaller droplet sizes are more prone to drift and may not deliver the fertilizer effectively to the intended location, making larger droplets the practical choice for surface applications where drift must be minimized.
