Outsider: No one is forcing you or anyone else to purchase organic produce and meat products.  It's a free market and free choice....provided, of course, that drifting herbicides don't contaminate the organic crop.  You obviously don't care.  Others do.  You can study the Oregon Tilth standards for organic produce...they're easily accessed.  Please remember, non-organic produce is readily available at your supermarket. 

You compare choosing organic products to adhering to a religion.  That's OK, I'll accept that. However, since that's the case, the religion "organic farming" is protected by the First Amendment and neighboring chemical farmers and timber growers are violating the Constitution when, with their intruding aerial spray, they preclude those organic farmers from exercising their "religion", the production of organic crops.
