Consistent effects of nitrogen fertilization on soil bacterial communities in black soils for two crop seasons in China

Abstract Long-term use of inorganic nitrogen (N) fertilization has greatly influenced the bacterial community in black soil of northeast China. It is unclear how N affects the bacterial community in two successive crop seasons in the same field for this soil type. We sampled soils from a long-term f...
