Evaluating the Impacts of Azotobacter chroococcum Inoculation on Soil Stability and Plant Property of Maize Crop

To clarify whether Azotobacter chroococcum iinoculation disturbs soil stability, as well as the variations of plant properties and maize yield, we assessed the impacts of A. chroococcum inoculation on soil stability and analyzed using frameworks of soil resistance and resilience and simultaneously evaluated plant properties and maize yield during a 4-year period from 2016 to 2019. The contents of plant total nitrogen (N) and total phosphorus (P) were apparently increased in A. chroococcum inoculation treatment relative to the control treatment of non-inoculation of A. chroococcum , by changing the contents of soil ammonium-N (NH 4 + -N) at the seedling stage (+17.78%) and heading stage (+34.48%), as well as soil nitrate-N (NO x -N; −23.94%) and soil available P (Olsen-P; −15.38%) at the heading stage ( P
