Soil microorganisms are crucial for nutrient cycling, with abundant and rare taxa playing distinct roles. However, the mechanisms by which soil microbes influence cycling under different crop types remain unclear. In this study, we investigated network structure, diversity, microbial composition of croplands in Yellow River Delta, focusing on four primary crops: soybean, maize, cotton, sorghum. The findings revealed that co-occurring structure sorghum planting-soils exhibited greater complexity than other types. Bacterial alpha diversity cotton-planting is highest susceptible to environmental variations. both responds differently nutrients depending type. While play a role multi-nutrient key drivers variations expression. showed strong correlation critical nutrients. Structural equation modeling bacterial fungal significantly influenced index (MNC). Specifically, higher Shannon indices were associated lower MNC, while opposite was true fungi. organic carbon total nitrogen factors influencing taxa. Moreover, study provides new insights into agricultural ecosystems.
