When is the ideal time to apply fertilizers to minimize runoff?

Applying fertilizers when rainfall is not imminent is the optimal choice to minimize runoff for several critical reasons. When fertilizer is applied right before significant rainfall, there is a much higher risk that the nutrients will be washed away into local waterways, contributing to nutrient loading and potential water quality issues such as algal blooms.

When no rain is forecasted immediately after application, the soil has a chance to absorb the nutrients. This allows the plants to effectively utilize the fertilizer, promoting healthy growth while reducing the likelihood that excess nutrients will enter runoff.

Additionally, during heavy rain or right before rainfall, the soil may not be able to absorb the nutrients efficiently, resulting in higher runoff rates. Applying fertilizer after a drought can also pose challenges, as the soil may be too dry to effectively take up the nutrients, and once watering resumes, it could lead to nutrient leaching during the first rainfall events following the drought.

Thus, timing fertilizer application for dry conditions without immediate rain helps ensure that the nutrients reach the plants while minimizing environmental impact.
