University of Minnesota Extension Soil Specialist Dan Kaiser is working on revamping fertilizer guidelines for dry edible beans. “There’s more questions starting to come in from growers that are wondering about our guidelines and shifts in the classes.” Kaiser’s research focuses on dry bean class comparisons, nitrogen, phosphorus, and potassium trials.” Kaiser says it’s been years since the guidelines were looked at, especially for black beans. “Specifically, we’re comparing black beans, navy beans, and dark red kidney beans to update some of the older data.”
