It’s so dry out West it can be measured by GPS

Researchers say the Global Positioning System, which helps drivers navigate the roads and which monitors tiny movements of the earth's surface as a possible indicator of developing earthquakes, has measured the huge loss of water due to severe drought in the West, says National Geographic.

Row-crop cultivators are being put to work because of the emergence of herbicide-resistant "super weeds," says DTN, "something of a renaissance" for mechanical weed control. Cultivators went into decline with adoption of limited-tillage and herbicides.
