Which technique enhances the nutritional quality of crops?

Biotechnology interventions are a powerful technique for enhancing the nutritional quality of crops. This approach utilizes advanced scientific methods, including genetic engineering, to develop crops with improved nutrient content. For example, scientists can insert specific genes into the plant's DNA to increase levels of vitamins or minerals that may be deficient in the diets of certain populations. These interventions can lead to varieties that are not only more nutritious but can also be designed to be more resilient to pests and diseases, further contributing to food security.

In contrast, while traditional cross-breeding methods can achieve some improvements in crop nutrition over time, they are generally slower and may not be as precise as biotechnology interventions. Soil amendment with organic material can improve the overall growth and health of crops but does not directly enhance the intrinsic nutritional quality of the plant's composition in the targeted way that biotechnology can. The use of pesticides is focused on pest control and does not contribute to the nutritional value of crops at all.
