Steam soil sterilization

jimmyd(z8b FL/Sunset28)February 21, 2003

Has anyone tried doing this "in the ground" on a small, home garden sized scale, with their own setup?

There are commercial scale steamers which are available for $5k plus. As I understand it, hollow tines or spikes on the back of a tractor are pulled through the soil as steam is passed through them.

It would seem fairly easy to build a boiler and pipe steam to,say, a raised bed which is underlain by perforated pipe. Not mechanically inclined, however, I am afraid if I tried to build it, the whole deal may explode in my face. Would love to know if anyone has thought about or tried this.

Cool thought! If not mechanically inclined, high pressure steam is a dangerous thing, if inclined, it is only scary. Maybe a local rental yard can rent one for $50 or so a day. Whatcha killin, fire ants? What about black plastic sheeting and Florida Sunshine?

I'm trying to kill nematodes in my sandy raised bed without chemicals.

The plastic is a good thought, but I'd lose a whole season of growing (I grow early spring to late summer). A steam pressure washer would seem to work except I don't need the water shooting out of it, just the steam.

Thanks for the reply!
