I have a multifarm. This is a picture of the boiler.

In theory, it is supposed to be self-sustaining. The powered furnace turns the wood into charcoal and feeds it into the boiler. The boiler makes steam and feeds power to the tesseract and the multifarm. What annoys me is that it needs a constant supply of dirt to turn into Humus. Can I configure it so that it uses normal dirt instead of Humus?
