Which of the following describes soil fumigation?

Soil fumigation is primarily utilized in high-value agricultural settings, such as golf courses, where it serves to manage soil-borne pests, diseases, and nematodes effectively. This method involves the application of fumigants, which become gaseous and penetrate the soil to target harmful organisms while minimizing risks to beneficial soil microbes. The high value associated with golf courses justifies the investment in such a specialized pest control strategy.

In contrast, options that suggest soil fumigation is cost-effective for residential lawns, a technique for enhancing soil nutrients, or an easy DIY method do not accurately reflect the complexities and requirements involved in fumigation processes. Residential lawns often benefit more from other pest control strategies that are simpler and more cost-effective. Enhancing soil nutrients typically involves different practices, such as fertilization or organic amendments, rather than fumigation. Lastly, the need for precise application techniques and safety measures associated with fumigants makes it unsuitable as a DIY solution.
