What aspect of fertilizer application is emphasized by recommending multiple small applications?

The recommendation for multiple small applications of fertilizer is primarily linked to environmental sustainability. This approach reduces the risk of nutrient runoff into water bodies, which can lead to pollution and harmful algal blooms. By applying smaller amounts of fertilizer more frequently, plants are better able to absorb the nutrients they need, minimizing the chances of excess nutrients leaching into the soil or running off during rainfall.

Furthermore, this method helps maintain soil health and fertility over time, promoting a balanced ecosystem. It ensures that nutrients are available to plants when they need them most, which not only supports robust growth but also protects surrounding environments from potential damage caused by over-fertilization.

In contrast, other factors such as efficiency in production, pest resistance, and soil compaction reduction may be relevant in different contexts but do not directly address the primary environmental benefits of applying fertilizer in smaller, more frequent doses.
