Although there is increasing awareness of the potential role of organic N compounds (ON) in plant nutrition, its implications for soil organic matter (SOM) stabilization have hardly been discussed yet. The aim of this paper is therefore to gather the newest insights into plant use of high molecular mass organic N, its effect on root growth and anatomy, and finally, to discuss the implications of plant use of organic N for SOM stabilization. I propose that modified root growth due to the uptake of ON provides greater root and root-associated microbe input, leading to enhanced SOM stabilization. Finally, I discuss the role of the proposed framework in different ecosystems, and I encourage future studies combining plant N nutrition and SOM stabilization.

尽管人们越来越意识到有机氮化合物 (ON) 在植物营养中的潜在作用，但尚未讨论其对土壤有机质 (SOM) 稳定的影响。因此，本文的目的是收集关于植物使用高分子量有机氮、其对根生长和解剖结构的影响的最新见解，最后讨论植物使用有机氮对 SOM 稳定的影响。我建议，由于吸收 ON 而改变的根生长提供了更大的根和与根相关的微生物输入，从而增强了 SOM 的稳定性。最后，我讨论了提议的框架在不同生态系统中的作用，并鼓励未来将植物氮营养和 SOM 稳定相结合的研究。
