You have to farm "organic" for 3 yrs before you can sell the crop as "organic", correct  ?

In a sense, cleansing the soil of pesticides.

What is the point of that if you can apply manure from a CAFO which almost certainly fed grain from fields produced with pesticides and GMO's ????

If you're going to tell me that the manure contained no pesticides then I'm going to ask if the grain contained pesticides?  

If you say the grain contained no pesticides then I'm going to ask why bother with "organic" production at all?

How much testing for pesticide residue do they do for "organic" grain?       Or is it simply paperwork/good faith?
