Question

How can soil pollution be sterilized? ​

Answer 1

Answer:

The most commonly used technique for sterilization is autoclaving of the soil. Another technique is irradiation with high‐level gamma radiation (γ‐radiation). One major drawback of sterilization procedures is the possible alteration of the structure of soil components, for example the organic matter.

Answer 2

Explanation:

Soil scientists wanting to sterilize the soil expose it to high-pressure steam for 30 minutes or more in an autoclave. Often, because soils are notoriously hard to sterilize, they repeat the process.
