University of Idaho faculty Karen Humes and Russell Qualls, along with their students, analyzed 30 years of crop water use data in southern Idaho to understand variations in irrigation application needs. Their research examined how differences in wet versus dry years and cool versus warm years influence crop water use and irrigation needs. By considering forecasted climate conditions, farmers can make informed decisions about crop selection and irrigation allocation, optimizing water use and improving overall agricultural efficiency.
