SAMD00009361 229036 uncultured AMF fungus The long-term field fertilizer experiment was conducted at Fengqiu Agro-ecological Experimental Station, Chinese Academy of Sciences, Fengqiu County, Henan Province, China (35°00’N, 114°24’E). The soil, a typical soil in the North China region with a profile of sandy loam (about 9% clay, 21.8% silt) and classified as aquic inceptisol (a calcareous fluvo-aquic soil). The treatments were: (1) NPK applied as urea, superphosphate, and potassium sulphate, respectively; (2) Organic manure (OM, i.e., total N at the same rate as in the NPK treatment, but from compost plus chemical P and K fertilizers as in the NPK treatment); (3) Control, i.e., no fertilizer. Each plot had received the same fertilizer management since 1989.
