Improper moisture levels may limit effectiveness

The correct answer is: Improper moisture levels may limit effectiveness

When conducting soil fumigation, it is crucial to maintain appropriate moisture levels in the soil, as proper moisture is essential for the effectiveness of the fumigants. In extremely dry soil conditions, the efficacy of the fumigant can be significantly limited because the gas may not travel through the soil effectively, reducing its ability to penetrate and control pests or pathogens. Proper moisture helps facilitate the movement of the gas throughout the soil, allowing it to reach the targeted organisms more effectively. If moisture levels are too low, the fumigant might dissipate quickly, fail to bind to the soil particles, or not penetrate deeply enough to reach the intended targets. Therefore, ensuring optimal moisture levels is a key consideration in soil fumigation practices, making the avoidance of improper moisture levels critical for successful outcomes.
