"I have always wondered who are these farmers in the dirt in the early morning?"

Southern California vineyards, for one. Come work in 100+F heat at 9:30AM.

I'm not sure that vinyards really match the description of the grain farmer in the article. But maybe I read too into their description.

Still, there is no set pattern of farmer behaviour. It is interesting that the idea of get up early has become so pervasive.
