What chemical is used to sterilize soil?
Ethylene oxide, propylene oxide, and methyl bromide are effective soil-sterilizing agents. The length of exposure time for sterilization depends upon the concentration of the sterilant, temperature, and initial microbial population of the sample (Caputo & Odlaug, 1983; Korczynski, 1981).
How do you pasteurize soil?
