Pasteurize Manure before Making Tea?

[Cole_Robbie]

I'm trying to set up my first manure tea experiments. My manure will be black dirt scraped up out of the cow field.

What would be the difference in the end product if I pasteurize the manure first in the microwave? Or does pasteurization kill off too many good bacteria? I am leaning towards pasteurization, because I don't want bugs and insect larvae hatching out of my manure sample.
