Democratic presidential hopefuls keep it brief on ag policies at Iowa State Fair speeches
Although ethanol and renewable fuels were broached often in previous elections in Iowa, including in 2008, many presidential hopefuls shifted the conversation to trade and climate change when talking about agriculture.
Ohio Rep. Tim Ryan, former Colorado Governor John Hickenlooper, Washington Gov. Jay Inslee called for greener farming techniques, and Ryan said regenerative farming could potentially increase profits for farmers.

Inslee mentioned the effects of climate change on Iowa farmers, having seen flooded fields after heavy rains and high river levels this spring on both sides of the state. He also called for more biofuels and alternative energy.
