Abstract
Soil health serves as a fundamental guarantee for sustainable agricultural development, directly impacting food security, ecosystem stability, and the regulation of global climate change. This article explores the multidimensional connotation of soil health and provides a comprehensive review of recent research progress in key areas such as soil microbial community structure and function, soil organic carbon management, optimization of tillage and fertilization practices, and soil degradation control. Studies have shown that soil microorganisms play a central role in maintaining nutrient cycling, enhancing crop stress resistance, and improving resource use efficiency. Scientific carbon management strategies and long-term appropriate tillage and fertilization regimes contribute to the construction of efficient and stable soil ecosystems. In recent years, plant-microbe-soil integrated remediation technologies have demonstrated great potential in restoring the functions of degraded soils. Further analysis indicates that enhancing soil health in the context of climate change is crucial for improving the adaptability and resilience of agricultural systems. Looking ahead, research on soil health should strengthen interdisciplinary integration and promote the synergistic evolution of precision management technologies and comprehensive remediation approaches, thereby providing a solid foundation for the green transformation and sustainable development of global agriculture.
