How plants trade\u2010off these strategies determines the economy of N use and is likely context\u2010dependent. Yet, it is rarely quantified\n                    <jats:italic>in situ<\/jats:italic>\n                    across growth stages and under varying management, limiting the mechanistic understanding of how plants rebalance N\u2010use trade\u2010offs to adapt to grazing disturbance. To address this gap, we conducted an\n                    <jats:italic>in situ<\/jats:italic>\n                    experiment using\n                    <jats:sup>15<\/jats:sup>\n                    N isotope labelling techniques in a semiarid grassland to quantify the contributions of these two strategies at two plant growth stages under nil, summer or autumn grazing. We found that the plant relied more on soil N uptake (58%) during the regreen stage, but more on N remobilization (57%) during the rapid\u2010growth stage. Grazing, especially in autumn, significantly leaned N use trade\u2010off toward conservative N remobilization. The shift in plant N use strategies was driven primarily by plant growth demand and soil N supply, but not root N stock. Plant N use trade\u2010off leaned toward internal cycling when source traits were below or sink traits were above the thresholds, for example, soil N availability &lt;9.0\u2009mg\u2009kg\n                    <jats:sup>\u22121<\/jats:sup>\n                    or shoot carbon content &gt;41.88%. Our study highlights the importance of the N resource\u2010sink relations in mediating the trade\u2010off in plant N use strategies, buffering grazing stress to grassland plants. These findings provide a mechanistic basis for improving ecosystem N cycling modeling and adaptive grazing management.\n
