I use "more primitive" based on the assumption that less focused development has gone into the technology for organic farming than chemical farming but if the word provides a negative connotation then, well, that's not what I mean.

One of the things I wanted to chime in with, somewhere in the discussion, was that this is the sort of policy which pushes people to develop technologies and that perhaps if deployed more slowly it might have driven innovation in organic farming.

Something like a pilot scheme + opt in + subsidies.
