description Cultivating ecological benefits in agricultural systems through greenhouse gas emission reduction will offer extra economic benefits for farmers. The reported studies confirmed that organic fertilizer application could promote soil carbon sequestration and mitigate greenhouse gas emissions under suitable tillage practices in a short period of time. Here, a field experiment was conducted using a two-factor randomized block design (organic fertilizers and tillage practices) with five treatments. The results showed that the application of microbial fertilizers conserved soil heat and moisture, thereby significantly reducing CO<sub>2</sub> emissions (6.9–18.9%) and those of N<sub>2</sub>O and CH<sub>4</sub> fluxes during corn seasons, compared with chemical fertilizer application. Although deep tillage increased total CO<sub>2</sub> emissions by 4.9–37.7%, it had no significant effect on N<sub>2</sub>O and CH<sub>4</sub> emissions. Application of microbial organic fertilizer increased corn yield by 21.5%, but it had little effect on the yield of wheat. Overall, application of microbial fertilizers significantly reduced soil GHG emission and concurrently increased yield under various tillage practices in a short space of time. With this, it was critical that microbial fertilizer be carefully studied for application in wheat–corn cropping systems.
