flag Iowa farmer tests Kernza, a sustainable perennial grain, for resilience and viability in local conditions.

flag Farmer Lee Tesdell in central Iowa is growing Kernza, a perennial grain from intermediate wheatgrass, on a seven-acre plot to test its viability in the state’s climate. flag The deep roots help reduce soil erosion and absorb nitrates, potentially improving water quality amid ongoing concerns over high nitrate levels in drinking water. flag Tesdell uses the crop for grain, hay, and sheep grazing, processing it into flakes or brewing ingredients via a Nebraska partner. flag While Kernza requires fewer inputs and tractor passes than annual crops, its low yields and limited market demand hinder widespread adoption. flag Though promising in drier regions and Minnesota, research continues on its performance in Iowa, where it remains experimental.
