This week's Open Mic guest is Tim Lust, CEO of the National Sorghum Producers. As the group prepares to celebrate their 70th anniversary, sorghum growers face daunting challenges from a loss of export markets and a future that hinges on developing domestic demand from renewable fuels and new market opportunities. He says the race for acres is an obstacle for growers as is adequate water to raise crops and maintaining profitability for growers who face rising input costs. Farm policy improvements in HR-1 were a benefit for growers, but Lust says they still need advancements in a new farm bill.
