It used to be possible to cover the soil with plastic and fumigate 
it by injecting methyl bromide.  I'm not sure it's legal any more.  Steam 
sterilization might be your best bet.  You may be able to rent the steam 
room at a commercial mushroom plant.  Commercial mushroom growers use a 
sterilized culture medium to maximize mushroom yields.  That's the only 
place I can think of that would be all set up to sterilize tons of soil.
