To address the existing knowledge gap regarding the relationship between the availability of Iron (Fe) and different N forms applied (nitrate, ammonium, or urea), the molecular mechanisms activated by plants to promote their acquisition have been investigated using omics data integration (\u201cexudomic\u201d\u2009\u00d7\u2009transcriptomic analyses). The transcriptomic and metabolomic analyses reveal a strong crosstalk among nutritional pathways, showing that tomato root responses to Fe resupply depend on the nitrogen form provided. Transcriptomic profiles after 4\u2009h indicate similar responses under urea and ammonium, a trend also observed at the exudomic level after 24\u2009h. Distinct molecular features emerged depending on the specific N form applied. In particular, Fe resupply with urea induced the upregulation of the expression of\n                    <jats:italic>FER<\/jats:italic>\n                    and\n                    <jats:italic>bHLH66<\/jats:italic>\n                    , moderately enhancing the Fe level in roots. Overall, integrated omics data highlight a complex network of transcription factors, metabolites, and transporters that may contribute to improved plant resilience under nutrient stress, such as transcription factors (bHLH, MYB, ZAT12), transporters (UMAMITs, MATEs) and a proteolytic regulator of a phenylpropanoid enzyme (KFB\u2010PAL). Within the framework of sustainable agriculture, this study corroborates the occurrence of a strong interplay between Fe\u2010 and N\u2010nutritional pathways and emphasizes how different N forms can modulate root exudation in the rhizosphere, thereby enhancing the uptake of other essential nutrients such as Fe.\n
