Why is monitoring weather forecasts critical in fertilizer application?

Monitoring weather forecasts is critical in fertilizer application primarily to avoid runoff and leaching. Weather conditions, such as heavy rainfall or high winds, can significantly affect how fertilizers are applied and their effectiveness. If a fertilizer is applied just before a heavy rain event, it may wash away, leading to nutrient loss and potential contamination of nearby water sources. This not only reduces the efficiency of the fertilizer application but also contributes to environmental issues, such as water pollution.

Additionally, understanding weather patterns helps practitioners identify the optimal timing for applications, ensuring that nutrients are available to crops when they need them most while minimizing the risk of nutrient loss. Proper timing, informed by accurate weather forecasts, enables applicators to make strategic decisions that enhance the sustainability of their practices.
