Farmers right now are not selling because they are to busy tending soil in this very early spring. Demand is the main cause of tightness of supply. Back months are being bought for future delivery, because front month is already spoken for. China will be back for more beans after long term Argentina trucker strike. Even though export sales not surfaced this week...I think this weeks export sales might be a wake up call. Ask Jim Cramer if he knows anything about grains...I rest my case---lol
