How does biotechnology contribute to reducing chemical fertilizer use?

Biotechnology significantly contributes to reducing chemical fertilizer use by enhancing crops' nutrient use efficiency. This means that genetically engineered plants are designed to absorb and utilize nutrients from the soil more effectively. Through various biotechnological advancements, such as the incorporation of specific genes that improve the plant's ability to uptake nitrogen or phosphorus, these crops can thrive with lower amounts of chemical fertilizers.

By focusing on improved nutrient use efficiency, farmers can achieve better crop yields while minimizing the environmental impact associated with excessive fertilizer application, such as soil degradation and water pollution. This aligns with sustainable agricultural practices, fostering resilience in crop production while addressing issues like nutrient runoff and dependency on chemical fertilizers.

Other options do not effectively capture this vital relationship. Increasing the soil's nutrient content doesn't inherently relate to crop efficiency or the reduction of fertilizer use. Developing crops that require chemical fertilizers contradicts the objective of reducing reliance on them. Promoting traditional farming practices may have benefits, but it does not specifically utilize the advancements brought by biotechnology in increasing nutrient efficiency.
