Monitoring ozone from space:
Satellite views of the Midwestern United States show that ozone levels above 50 parts per billion (ppb) along the ground could reduce soybean yields by at least 10 percent, costing more than $1 billion in lost crop production. (8/29)

Boosting organic production:
Studies by USDA scientists indicate that organic farmers who need to periodically amend their soils with compost after planting can still control weeds--and hold down costs--by using fabric ground covers. (8/30)

More potatoes, less water:
Research conducted in part at USDA has confirmed that in some production systems, planting potatoes in flat beds can increase irrigation water use efficiency. (9/1)
