As a vital root vegetable, radish exhibits a yield formation process closely intertwined with the dynamic fluctuations of soil nutrients. Focusing on the spatiotemporal variation characteristics of key nutrients—specifically nitrogen, phosphorus, potassium, and organic matter—during radish cultivation, this study systematically analyzes the comprehensive mechanisms by which root uptake, fertilizer inputs, and environmental factors collectively influence the soil nutrient cycle throughout the crop's growth stages. Through field experiments and phased monitoring data, the study investigates the processes of soil nutrient depletion and replenishment across different growth periods, with a particular emphasis on elucidating the pathways of nitrogen transformation and loss, the mechanisms of phosphorus fixation and release, and the patterns governing potassium exchange equilibrium. Building upon this foundation, and by incorporating variations in fertilizer management regimes, an analytical framework for assessing soil nutrient dynamics is constructed to evaluate nutrient utilization efficiency and the evolutionary trends of soil fertility. Case studies further validate the patterns of soil nutrient variation under different fertilization strategies, as well as their subsequent impacts on radish growth and yield formation. The results demonstrate that optimizing fertilizer composition—particularly when combined with organic soil amendment measures—can effectively enhance nutrient utilization efficiency, minimize nutrient loss, and improve soil ecological stability. This research provides both a theoretical basis and practical guidance for the scientific fertilization and sustainable soil management of root vegetables.
