Changes in the Microbial Community in Maize (Zea mays L.) Root Spatial Structure Following Short-Term Nitrogen Application.

ABSTRACT: The beneficial interactions between crop roots and microbiomes play a key role in crop nutrient availability, growth promotion, and disease suppression. Recent research, however, rarely reported the effects of nitrogen (N) application rate on microbial community composition at different spatial structures in the maize root zone. Therefore, one experiment was conducted to examine the influence of three N-application levels (0, 180, and 360 kg N ha^-1) on microbial community composition in three root-associated compartments of maize (bulk soil, rhizoplane, and endosphere). The microbial diversity and community composition differed significantly among the various compartments. The effects of N application on fungal composition decreased in the order bulk soil > rhizosphere > endosph
