The sustainability of agroecosystems depends on the maintenance soil organic matter (SOM) and aggregate stability, which are key components health. long-term effects conservation management systems, such as adoption no till (NT) associated with cover crops, quality still unclear. aim this study was to evaluate NT systems combined cropping ecologically intensified by presence legumes carbon index (CMI) state aggregation, sensitive tools assess systems. autumn spring legume crops increased proportion aggregates > 2 mm, resulting in higher weighted average diameters aggregation values comparison conventional tillage (CT), favored microaggregate proportion. C content only surface layer, while use stock 23% compared system without 0–20 cm layer. In topsoil under NT, stocks particulate (POM) mineral-associated (MAOM) were 100% 37% greater than CT, respectively. A CMI observed CT (18%), one (52%), two (72%) crops. These results highlight till’s positive impact health, further enhanced legume-based ecological intensification
