Burned soil in oven, how toxic is it? Useful for something?
I had sterilized some soil in the oven, but I left it there to cool off. ... My wife was just making dinner and preheated the oven to 350 ... then yelled "WTF honey!" My response, "did you just heat the oven?!"
Then of course I apologized for leaving stuff in the oven, definitely my bad.
But now I have soil that is certainly toxic to plants to some degree. That is according to the websites I read about how to sterilize soil in the oven -- don't let it go over 200F they say. I could not find information on what to do if there's an oops though.
The soil in question is a mix of used potting soil from various dead plants of different sources. I'm airing out the kitchen because I'm concerned about what happens to possible fertilizers and whatever else was in the soils when it burns, at least at 350F. Any input on that would be helpful too.
Do I need to dump the soil in the trash? Can I detoxify it somehow? Would it ruin our compost?
Thanks for any info or suggestions.
