The wild battle in Arkansas over dicamba, the controversial and drift-prone herbicide, just got even crazier. Local courts have told some farmers that they don't have to obey a summertime ban on dicamba spraying that the state's agricultural regulators issued last fall. The state has appealed.

In American farm country, a grass-roots movement is spreading, a movement to keep more roots in the soil. (Not just grass roots, of course; roots of all kinds.) Its goal: Promoting healthy soil that's full of life.

I met three different farmers recently who are part of this movement in one way or another. Each of them took me to a field, dug up some dirt, and showed it off like a kind of hidden treasure.

"You can see how beautiful that soil [is]," said Deb Gangwish, in Shelton, Neb. "I'm not a soil scientist, but I love soil!"

Robots have arrived at Bill and Carol Shuler's farm near Baroda, Mich., and life has taken a turn for the better.

"It absolutely changes your lifestyle. It gives you a life!" says Bill Shuler.

For decades — for the entire time that Bill and Carol have been married, in fact — the Shuler family's routine was practically set in stone: Get up at 3:45 a.m., clean the barn, feed the cows and milk them. Then get breakfast and take care of other work around the farm. At 3 p.m., go back to the barn to feed and milk the cows again.

The U.S. Department of Agriculture has decided that organic food companies can keep using an emulsifier called carrageenan in foods like ice cream and high-protein drinks, despite a vote by an influential organic advisory committee to ban the ingredient.

Robots have taken over many of America's factories. They can explore the depths of the ocean, and other planets. They can play ping-pong.

But can they pick a strawberry?

"You kind of learn, when you get into this — it's really hard to match what humans can do," says Bob Pitzer, an expert on robots and co-founder of a company called Harvest CROO Robotics. (CROO is an acronym. It stands for Computerized Robotic Optimized Obtainer.)
