What should be avoided to maintain water quality in sensitive areas during fertilizer application?

Applying too much fertilizer can lead to nutrient runoff, which significantly contributes to water quality issues in sensitive areas. When fertilizers are applied in excess, they can leach into nearby waterways during rainfall or irrigation, leading to nutrient pollution. This can cause problems such as algal blooms, which deplete oxygen in the water and harm aquatic ecosystems.

Understanding proper application rates and timing is crucial for minimizing environmental impact. A balanced approach, where fertilizers are applied according to soil test recommendations and crop needs, is essential to protect water quality and promote healthy agricultural practices.

Other options, such as mixing fertilizers or not applying fertilizers at all, do not inherently impact water quality in the same manner, as they can be managed properly. Additionally, using only organic products may not always address the specific nutrient needs of crops or alleviate water quality concerns if applied excessively. Hence, careful management of fertilizer application rates is vital.
