I've always hated the northern Idaho spring ritual of burning off their fields. But this morning, I had a thought: does the brief heat of the fire kill off parasites in the soil? Would burning off a field reduce cocci?

If it does....loath as I am to say this, it would be an effective weapon in combatting parasites on an organic farm with livestock, since my understanding is that worming medicines and coccidiostats are not approved for use if you are certified organic.
