Correct Answer:

To avoid over-fertilization and environmental harm

Explanation:

Considering soil nutrient levels before fertilization is crucial because it helps to avoid over-fertilization, which can lead to significant environmental harm. By assessing the existing nutrient content in the soil, farmers and agricultural professionals can make informed decisions about the amount and type of fertilizer needed. This ensures that crops receive the nutrients they require for optimal growth while minimizing the risk of nutrient runoff into waterways, which can cause water quality issues, such as algal blooms and the degradation of aquatic ecosystems. Furthermore, proper nutrient management promotes sustainable agricultural practices by enhancing soil health and productivity over time.
