Abstract
As an important agricultural management practice, crop rotation has significant long-term effects on soil fertility and nutrient cycling. This article explores the impact of crop rotation on soil nutrient dynamics, soil organic matter accumulation, and nutrient release and utilization efficiency, analyzing its role in enhancing agricultural sustainability and soil health. This article covers the cycling of major nutrients (nitrogen, phosphorus, potassium) and trace elements, as well as the long-term effects on soil organic matter and nutrient release mechanisms. Through long-term field experiments, soil nutrient level measurements, crop yield, and fertilizer requirement records, soil chemical analyses, and nutrient modeling applications, this article evaluates the actual effects of different crop rotation systems on soil fertility and nutrient cycling. These findings not only reveal the contribution of crop rotation to soil health and crop productivity but also provide a scientific basis for formulating fertilization strategies and optimizing agricultural management practices. The primary aim of this article is to provide empirical support for promoting sustainable agricultural development by gaining a deeper understanding of the long-term effects of crop rotation, ensuring efficient resource utilization, and sustainable environmental health.
