Gansu private entrepreneur Liu Yisheng is a senior land "nutritionist" and the person in charge of Gansu Sudi Fertilizer Co. Ltd.
He said that testing soil and fertilizing is like a "physical examination" of the land. He likened the land to the human body and fertilizer to food. "Only when you eat right can you grow well. Although this principle is simple, it is easily overlooked," he said. "My biggest wish is to allow every farmer to grow good crops, make the land more fertile, and make agriculture more green"
