Dr. Terry Roberts visited EI sites for winter wheat in Hebei Province

On April 19, 2015, Dr. Ping He accompanied Dr. Terry Roberts, Dr. Adrian Johnston, and Dr. Rob Mikkelsen to visit EI experiment in Dahe Experimental Station in Shijiazhuang, Hebei Province. The site in Dahe represents double cropping of winter wheat with summer maize in relatively high soil fertility and high environmental sources of nutrients. Although not much differences between EI and FP treatments for winter wheat from field, we saw growth deduction from N omission plot after 10 crops planting.
