This post at Technology Review describes the potential for really precision agriculture--essentially applying the "internet of things" to tomato growing in New England. Did you know New England tomatoes are different than tomatoes grown elsewhere (as in warmer climates)? There's potential for using technology to monitor growing tomatoes .
I suspect this represents one set of developments in future agriculture, where farmers lose their rednecks (I've got one--from bending over in the garden) by much more intensive use of technology. There will be a further bifurcation of farmers:
So on one hand we'll have the tech-farmers, investing more capital into much more precise control of growth. I'd count the vertical farmers of leafy greens as other examples. This agriculture will be seen as much less "natural" than today's.
On the other hand we'll have the artisan farmers, who will be more organic and grow more diverse crops (heirloom tomatoes, etc.)
