When you think a little about it, this is obvious. this agricultural research is done in monoculture and with very little labour. Part of the reason why it's done in monoculture is because of methodological reductionism: the conditions of the study have to be as simple as possible in order to be able to isolate factors and run statistical analyis. In other words, in an organic patch the "experimental setup" is "messy".

Food for thought.
