Soil microbial communities participate in organic-matter decomposition, nitrogen transformation, and phosphorus mobilization. Their structure is influenced by soil organic carbon, nitrogen and phosphorus contents, pH, and plant-root exudates. This paper analyzes changes in bacterial, fungal, and archaeal communities under different nutrient conditions and discusses the bidirectional relationships among microbial diversity, functional guilds, and soil nutrient availability. The analysis indicates that greater nutrient availability does not necessarily increase microbial diversity. Community stability and nutrient-cycling functions can be maintained only through appropriate regulation of carbon, nitrogen, and phosphorus ratios and soil pH.
