What factors may require changes in planned soil fumigation?

Changes in planned soil fumigation may be necessary due to the presence of plant debris and soil moisture. Plant debris can affect the efficacy of the fumigant by acting as a barrier, potentially reducing its ability to penetrate the soil and reach target pests or pathogens. Additionally, the moisture content of the soil is crucial because it influences gas movement and distribution. High moisture can lead to volatilization of the fumigant, while dry conditions can limit its effectiveness.

Addressing these factors ensures that the fumigation process is optimized for the best results, aiming to achieve thorough pest control while minimizing any adverse environmental impacts. Proper assessment of the soil conditions, including the amount of plant debris and moisture levels, allows for adjustments in fumigation practices, such as altering the application method, rates, and timings to enhance efficacy.
