Someone suggested a while back that the best* way to sterilise some
garden soil or manure for putting on mushrooms would be to 'bake' it
in the oven.

What temperature and for how long would be effective?

Excellent, thank you

Just nuke it till it steams, no need to make life overly complex

Bit like a cake, it might not be done in the middle. Depends on how thick
the mix is. Clay or sandy. We don't want to over egg the pudding, or in
this case, under egg.
Just a lighthearted jape.

Most microwaves will not sterilise dry soil. The soil will have to be
wet all the way through. A bit like cooking a mud pie.

Damp, not wet, I use an old rat bait container (No metal handle)that
holds around 10 litres of soil, make sure that there are no stones in
the soil, and DON'T pack the soil in hard, loose works much better.
I give it around 20 mins on full power with a lid on loosely to hold the
steam in. Leave it to stand for half an hour before tipping it out.
If you have 2 containers then you can get quite a lot done in a morning.
I bought a cheap microwave for this,

For entertainment only, I will share my dad's method of soil
sterilisation.

He used a wooden box, probably an old packing case, inserted a
metal plate at each end and filled it with soil. The plates were
connected to the mains, via an ammeter. Then he added water
until the soil resistance lowered, and hence the ammeter reading
rose to the desired level. It was left to simmer for hours. I can
smell it now.

Wet is not currently an issue!

Also in the 40's and 50's they had soil warming using a step down
transformer and ordinary fencing wire put around 12 inches below the
soil surface.

It was crossing my mind as the whether he had a battery charger in the
circuit to cut it down to 12 volts. Seems a bit dangerous to apply 240 Volt
AC :-(
