Greetings all,

I was thinking of re-using some soil I'm had accumulating in a 60gall drum.
My main concern is that of any fungi or others pathogens that may be lurking
in this mix. Any ideas on how to sterilize this soil (it is much too
valuable to throw out). I've heard of ovens being used, was wondering if a
microwave was up to the job. This soil is comprised of 60/20/20 pine bark,
coarse river sand and lava rock respectively.

Any suggestions would be as usual - greatly appreciated

Martin
