Is that part of the requirements of getting certified organic? That is the reason people pay extra for the certified organic food. It's because they want to know where their food comes from and how it was raised. What's in the manure is what gets in the food. Why else would you need to use it?
I'm all for cheap food, don't get me wrong but I am also for quality as is most people who buy certified organic. The price will come down as the market continues to grow but if it's going to be compromised then what is the point?

Yes, you must provide proof that your soil hasn't been "contaminated" by commercial fertilizer.

Manure is the most natural form of fertilizer available. It provides all the nutrients for a healthy crop.
Commercial fertilzers, OTOH, are concentrated forms of these same nutrients. I see no problem with a farmer using commercial fertilizers since they are just concentrated forms of the natural types of fertilizers.
