Grains continue lower Tuesday for a third day, with cattle also lower.  Randy Martinson, Martinson Ag, says grain markets are seeing pressure from harvest, weather and renewed fund selling.  Grains are at important areas where technical support needs to hold or they could see a deeper selloff but there has been some export demand on the lower prices.  Cattle are lower on profit taking and hedge selling.  Lean hog futures are rebounding on short covering as funds defend their long position and cutouts were stronger.
