Data Sheet 1_Season-specific nitrogen management shapes soil microbial communities and crop productivity in wheat–maize rotation system.docx Mengru Xue (21499514) Wenyang Li (645610) Haosen Wei (24961420) Zerong Wang (2987661) Baojin Guo (8616498) Chuangyun Wang (19919952) Peng Zhou (116747) Fei Gao (29262) Plant Biology cross-seasonal effects nitrogen fertilizer use efficiency seasonal N carryover soil bacteria–fungi communities soil-crop system coordination winter wheat–summer maize rotation <p>Based on a long-term positioned field experiment in a wheat-maize double-cropping system, the regulatory mechanisms of nitrogen fertilizer legacy on soil-crop coordination and microbial functions remain unclear. A two-year field experiment was conducted with four treatments: CK: no N fertilizer applied during either wheat or maize seasons; W1M0: N carryover only during the winter wheat season; W0M1: N carryover only during the summer maize season; W1M1: N carryover during both wheat and maize seasons. Compared with the unfertilized control (CK), W1M0 and W0M1 increased average annual yields by 45.7% and 42.2%, respectively, while W1M1 increased by 58.6%. On average, W1M1 produced the highest yield (21.8 t ha^-1), with W1M0 and W0M1 achieving 91.9% and 89.7% of W1M1 yield, respectively. fertilization increased the abundance of predicted chemoheterotrophic functions. W0M1 influenced predicted N-transformation functions and fungal guilds. Bacterial community composition responded more strongly than fungal communities. Soil-crop coupling coordination varied dynamically with growth stages and N management patterns. PLS-SEM revealed that soil nitrogen content from the preceding wheat season explained 97.5% of the variance in subsequent maize soil physicochemical properties, which was 2.65 times higher than the corresponding explanatory power of maize-season N (36.8%), indicating a stronger predictive legacy of wheat-season N application on soil-crop coordination. In conclusion, seasonal N coordination is more crucial than total N input. Leveraging the superior legacy effect of wheat-season N application provides a scientific basis for precise fertilization regulation in rotation systems.</p> 2026-09-16T05:44:53Z Dataset Dataset 10.3389/fpls.2026.1938392.s001 https://figshare.com/articles/dataset/Data_Sheet_1_Season-specific_nitrogen_management_shapes_soil_microbial_communities_and_crop_productivity_in_wheat_maize_rotation_system_docx/33829336 CC BY 4.0
