There is increasing interest in biomass crops for energy in Iowa. Initially, it was thought that strong commodity prices would limit the interest of growers in planting perennials for bioenergy, but that doesn’t seem to be the case. A Biomass Crop Production workshop Thursday, March 8, at Southwestern Community College in Creston, Iowa will explore why interest is increasing. The program will start at 8:45 a.m. and conclude at 2:15 p.m.
