Abstract:

This study focused on carbon footprint and nitrogen fertilizer utilization in agricultural production, providing theoretical support for low-carbon production of dry rice. The carbon footprint (CFP) of the production process of upland rice was calculated by using life cycle assessment (LCA) methodology. The results showed that the carbon footprint of 1 kg Jilin upland rice from planting to product processing was 0.4721 kg CO2-eq. The carbon footprint of upland rice was mainly derived from nitrogen fertilizer production (39.71%) and land emission (20.41%). In conclusion, compared with rice, upland rice had no methane emission and had emission reduction effect. Optimization of fertilizer selection, rational reduction of nitrogen fertilizer application, application of controlled release fertilizer, addition of nitrification inhibitor, and rational substitution of organic fertilizer for fertilizer were important ways to further achieve carbon emission reduction of upland rice.

Key words: upland rice, life cycle assessment, carbon footprint, carbon emission reduction
