How can soil tilth be improved prior to fumigation?

Improving soil tilth is crucial for effective fumigation, as it ensures that the soil is in the best condition to facilitate the penetration and efficacy of the fumigant. Cultivating the soil to remove clumps and clods is vital because compacted soil can hinder the movement of the fumigant, reducing its effectiveness in controlling pests. Breaking up soil structure helps to create a more uniform texture, allowing gases to move freely through the soil. This is essential for ensuring thorough contact between the fumigant and potential pests or pathogens present in the soil.

While other strategies may contribute to overall soil health or management, such as adding organic fertilizers or removing plant residues, they do not specifically target the physical structure of the soil in the same direct manner as cultivation does. Increasing irrigation could lead to waterlogged conditions, which can also hamper fumigation effectiveness. Therefore, cultivating to achieve a finer, more workable soil texture is the best approach for improving soil tilth before fumigation.
