NW_GR312 Des Moines, IA May 31, 2019 USDA Market News Iowa Hay Summary Week Ending May 31, 2019 Prices were similar to last week, but the quality of hay continues to drop. With all the rain, the hay crop is standing tall. However, producers should be nearing first cutting but instead are waiting for the ground to dry so they can complete (start) soybean planting. States that ship excess hay and straw to Iowa are also running low, creating more headaches for livestock porducers.
