Biotechnology plays a significant role in enhancing soil quality through practices such as bioremediation. Bioremediation utilizes microorganisms or plants to remove or neutralize contaminants from the soil. This process improves soil health by breaking down harmful substances, promoting the growth of beneficial microbial communities, and increasing the overall fertility of the soil.

In contrast, while increasing mineral content or developing more competitive crops may contribute to agricultural productivity, these aspects do not directly address the quality of the soil itself. Additionally, although biotechnology can help mitigate certain contaminants, it does not eliminate all soil contaminants; some might persist or require different strategies for management. Thus, supporting practices like bioremediation is the most accurate representation of how biotechnology enhances soil quality.
