Abstract：The investigation on fertilization status was carried out in Tengzhou and Yanzhou,Shandong Province.Different recommended scenarios were made,and their impacts on GHG net emission and economic cost were studied and compared to fertilizing status by the calculation methods of carbon sequestration rate and GHG emission in farmland management.The results implied that the application of recommended fertilizers on wheat and corn could decrease GHG emission and economic cost.Especially the integrated application of base fertilizer and topdressing on corn,the GHG emission both decreased by 300 kgCe/(hm2 ·a)in Tengzhou and Yanzhou,the cost decreased by 2 700 yuan per hectare,and the carbon efficiency increased by more than 30%.In conclusion,the popularization and application of fertilizer recommended by the Ministry of Agricul-ture would have important environmental and economical values.
