Oh shiite, I didn't realize you were cooking in such small amounts. 20 gallons is about the minimum I cook at once for those very reasons. Hmmm. Maybe we need to do some research into cooking small batches. Does your outdoor compost heat up? I'm thinking maybe put your soil in a cloth bag and bury that in an active compost pile?2 gallons of soil is probably just too small to generate enough heat to overcome ambient air.
The other thing you could try is a pot drench. I do them when calcium isn't working when it should be. The water seems to activate the calcium. If it is a composting thing then your used soil is probably still quite fertile. Maybe you should try a test grow in a pot of just used unammended soil and see how it grows.
