Due to the characteristics of long-term ecological observation, certain parameters were monitored at multi-year intervals rather than annually. The dataset aims to elucidate the current status and temporal trends of soil fertility, environmental quality, and overall soil health in the regional farmland ecosystem, analyze the driving factors underlying soil quality dynamics, evaluate the current state and future trajectory of farmland ecosystem management, and thereby provide a scientific foundation for informed decision-making toward sustainable agricultural development in the region.
