“…Different cropping patterns alter the inputs and outputs of agricultural ecosystems, leading to variations in CF (Gan et al 2012;Yang et al 2014;Wang et al 2020). In our study, the CF of CC was significantly greater than that of CS due to greater agricultural inputs as well as straw and nitrogen fertilizer inputs in corn cultivation compared with soybean cultivation, in turn increasing carbon emissions from the continuous cropping system.…”

“…The CF of crop production can be reduced by changing management methods and implementing low-carbon technologies, such as conservation tillage, optimized irrigation, and fertilizer application (Zhang et al 2016;Yadav et al 2018). Wang et al (2020) assessed the CFs of four different cropping systems: cotton monoculture (CM), winter wheat intercropped with cotton (WIC), wheat cropping followed by transplanted cotton (WTC), and direct-seeded cotton after winter wheat harvest. The results indicated that CM was the best cropping system in low-fertility plots, whereas WIC was the cropping system with the lowest CF in high-fertility plots due to low inputs of fertilizer, labor, and diesel.…”

“…The results indicated that CM was the best cropping system in low-fertility plots, whereas WIC was the cropping system with the lowest CF in high-fertility plots due to low inputs of fertilizer, labor, and diesel. Therefore, appropriate improvements in cropping patterns and farming practices can reduce the CFs of crop production (Wang et al 2020). STR also has an important influence on CF.…”

“…Despite differences in these studies, they all demonstrate that indirect N2O emissions from the production, storage, and transportation of nitrogen fertilizer as well as direct N2O emissions from the application of nitrogen fertilizer are the most important components of total GHG emissions from crop production (Hillier et al 2009a;Cheng et al 2011;West et al 2014;Wang et al 2020). Therefore, reducing nitrogen fertilizer input and adopting a sustainable application method are crucial practices to mitigate agricultural GHG emissions from fertilizer application (Bacenetti et al 2016;Feng et al 2020).…”

Inappropriate farm management practices can lead to increased agricultural inputs and changes in atmospheric greenhouse gas (GHG) emissions, impacting climate change. This study assessed the potential of straw retention to mitigate the negative environmental impact of different cropping systems on the Songnen Plain using the life cycle assessment (LCA) method combined with field survey data. Straw retention (STR) and straw removal (STM) treatments were established in continuous corn (CC) and corn-soybean rotation (CS) systems in a split-plot experiment. The effects of straw retention on the carbon footprint (CF) of cropland under different cropping systems were compared. The CF under CC was 2434.0–2706.9 kg CO 2 ha -1 yr -1 , 49.3%–57.3% higher than that under CS. Nitrogen fertilizer produced the most CO 2 , accounting for 66.2%-80.4% of the CF. The carbon balances of the CC and CS systems with STR were positive, with annual carbon sequestrations of 9632.5 and 2715.9 kg CO 2 ha -1 yr -1 , respectively. The carbon balances of the CC and CS systems with STM was negative, with annual carbon sequestrations of -3589.2 and -3006.2 kg CO 2 ha -1 yr -1 , respectively. This study demonstrates that STR under CC cultivation is an environmentally friendly practice for agricultural production, can help achieve high-yield and low-carbon production in rainfed cropland, and can support the sustainable development of grain production in Northeast China.

Inappropriate farm management practices can lead to increased agricultural inputs and changes in atmospheric greenhouse gas (GHG) emissions, impacting climate change. This study was initiated in 2012 to assess the potential for straw retention to mitigate the negative environmental impact of various cropping systems on the Songnen Plain using the life cycle assessment (LCA) method combined with field survey data. Straw retention (STR) and straw removal (STM) treatments were established in continuous corn (CC) and corn-soybean rotation (CS) systems in a split-plot experiment. The effects of straw retention on the carbon footprint (CF) of cropland under different cropping systems were compared. The CF under CC was 2434–2707 kg CO2 ha−1 year−1, 49–57% higher than that under CS. Nitrogen fertilizer produced the most CO2, accounting for 66–80% of the CF. The carbon balances of the CC and CS systems with STR were positive, with annual carbon sequestrations of 9633 and 2716 kg CO2 ha−1 year−1, respectively. The carbon balance (CB) of CC-STR was 255% higher than that of CS-STR. This study demonstrates that STR under CC cultivation is an environmentally friendly practice for agricultural production, can help achieve high-yield and low-carbon production in rainfed cropland, and can support the sustainable development of grain production in Northeast China.
