What is an important consideration when planning fertilizer application based on weather?

When planning fertilizer application, avoiding application before rain is particularly important for several reasons. Rainfall following fertilization can lead to runoff, where nutrients are washed away from the intended application area and potentially pollute nearby waterways. Additionally, applying fertilizer right before a rain event can cause the nutrients to wash away before they have a chance to incorporate into the soil and be absorbed by plants. This results in reduced effectiveness of the fertilizer and can potentially lead to environmental issues.

In comparison, applying during hot weather might increase evaporation rates, which can lead to nutrient loss. Fertilizing in windy conditions can cause uneven distribution and reduce application efficiency as the wind can carry fertilizers away from the target area. While applying at night might reduce evaporation, it does not address the immediate risks associated with applying fertilizer before rainfall. Each of these factors should be carefully considered, but avoiding application prior to rain is crucial for maximizing nutrient uptake and minimizing environmental impacts.
