Scientists look to wheatgrass to save dryland farming and capture carbon

Reading Time: < 1 minute

Intermediate wheatgrass is an imported grain that has been grown in the U.S. Great Plains and Intermountain West since the 1930s; but could it be used in marginal fields in dryland areas? Kernza, an intermediate wheatgrass bred by the Land Institute, is being planted in eastern Wyoming, where researchers from the University of Wyoming are uncovering whether the crop can help farmers stabilize and bolster their soils, while providing a profitable crop. Planting perennial crops, like Kernza, can help soil health and stability, retain moisture, and cut down on planting costs and greenhouse gas emissions from annual plantings. Farming in eastern Wyoming is not for the faint of heart. The semiarid landscape receives unpredictable weather and is considered an unforgiving environment for agriculture. Despite this, farmers have grown annual winter wheat crops in eastern Wyoming, but at a cost. Given the harsh growing conditions, farmers note that with falling wheat prices, soil degradation, and variable weather, annual crops feel like a losing proposition. “Farmers — especially in this region, but across the country — are really looking for things that can give them some resilience in the face of climate change,” said Hannah Rodgers, a soil science doctoral student […]
