      abstract     = {Soil organic carbon (SOC) level is influenced by
                      incorporation of crop straw and application of nitrogen (N)
                      fertilizer, which are typical farming practices in intensive
                      agricultural regions. However, the interaction between the N
                      fertilization and crop straw incorporation on SOC levels is
                      still not univocally established, especially for calcareous
                      soils. We therefore conducted a 224-day laboratory
                      incubation experiment with four levels of 13C-labeled maize
                      straw amendment (0, 1 ×, 3 × and 5 × of maize straw
                      yield) and three N fertilization rates (0, 300, and 600 kg N
                      ha− 1 a− 1) on a Fluvic Cambisol to investigate the
                      short-term response of SOC content. The 13C-labeled straw
                      allowed partitioning of the CO2 produced from native SOC or
                      crop straw for application to a two-compartment exponential
                      decay model to simulate the addition of new SOC from the
                      straw and the decomposition of the native SOC. The addition
                      of maize straw caused immobilization of inorganic N during
                      the incubation. Increased mineral N fertilization
                      significantly inhibited the decomposition of maize straw,
                      which led to the increased new SOC from maize straw
                      amendment. Priming effect (PE) of native SOC decomposition
                      peaked at 40 days after incubation, and then decreased until
                      the end of the incubation. N fertilization significantly
                      enhanced the cumulative PE when maize straw was not added
                      (N2 induced PE at C0 was + $19\%$ of C0N0 SOC
                      decomposition), but had no significant effect when the
                      highest rate maize straw was amended (N2 induced PE at C5
                      was $8\%$ of C0N0 SOC decomposition), indicating that maize
                      straw amendment can moderate the PE promoted by N
                      fertilization. There was a positive linear correlation
                      between the cumulative PE and the input of maize straw C. An
                      increase in maize straw incorporation with N fertilization
                      caused the largest increase in total SOC content at the end
                      of 224-day incubation (the highest $23.7\%$ for C5N2
                      treatment, i.e., 5 × maize straw yield + 600 kg N ha− 1
                      a− 1). Our findings highlight that in intensively managed
                      agricultural regions, integrating N fertilization with crop
                      residue amendment can promote SOC sequestration and the
                      retention of fertilizer N in the soil. The results are
                      particularly relevant for developing new or improved farming
                      methods in areas with calcareous soils, such as northern
                      China.},
