The grains prices have been moving up this week.  Agrivisor analyst Dale Durchholz says it is an international thing between Russia and Ukraine.  Ukraine is a major producer and exporter of both corn and wheat with good growing conditions.  The situation between Russia and Ukraine is stressful and disruptive to the crop production.  He says there could be more to it than that and it could be a good marketing opportunity for producers here.  At the Gateway FS elevator in Nashville, corn has gone up 22 cents and wheat has gone up 31 cents since opening Monday morning.
