AB  - The poor fertility of Martian regolith, due to its lack of organic matter (OM) and nitrogen (N), limits its suitability as a plant substrate. While compost amendment enhances short-term fertility, the mechanisms underlying long-term OM stabilization, particularly through interactions with iron (Fe) minerals, remain poorly understood. This study explores OM fractionation and Fe mineral transformations in Mojave Mars Simulant (MMS-1), both pure (R100) and amended with compost (R70C30), across two consecutive cropping cycles (potato followed by Vicia faba). Following Vicia faba cultivation, total C increased 12-fold in R70C30 (18.8 g kg<sup>−1</sup>) compared to R100 (1.6 g kg<sup>−1</sup>), with a 140
