Organic could be less expensive too. 

I'm thinking electric powered farm machinery that aids labor intensive farming. 

Riding carts, with shade and dust protection, between the rows pulling water and liquid organic fertilizer, or mulch, that is programmed to weed and feed by itself by the operator, who rides along ocasionally correcting it. 

The computer in the cart "learns" where the plants are, where to water and weed.

Water and fertilizer right to the plants, weeds sucked up and shredded into mulch.  Bugs eating too much of the plants sucked into the mulch too.

Harvesting all done from a comfortable situation too.  This would make labor intensive organic farming actually enjoyable.  A great job.

Planting as well, seedlings and seeds all placed by the robot arms, controllable by hand but programmable.

This would raise productivity and lower costs without chemicals or genetic engineering.  Good old humans who love gardening helped out with better tools, computers and robot arms.
