Effects on Soil Bacterial Organism in an Alfalfa Monocropping System After Corn Insertion and Nitrogen Fertilization

Alfalfa (Medicago sativa L.) and corn (Zea mays L.) are common forage plants for feeding livestock, and their effects on the bacterial community have been extensively studied, but there is little comprehensive research on the bacterial community and functional groups in a long-term continuous alfalfa cropping system after corn insertion and fertilization. The effects of alfalfa-corn rotation (AF: alfalfa monocropping, RA: alfalfa and corn rotation) and nitrogen fertilization (RA0 and RA15) were investigated in a field experiment.
