To face up to this situation, conservation agriculture offers an opportunity to reverse this alarming trend. Indeed, several international studies have confirmed the positive findings of conservation agriculture in view of its impact on the structural stability which closely related to soil organic matter (SOM). This work contributes to focus the impact of no tillage (NT) after ten years of experiment, on the structural stability, SOM and bulk density (Da) of a Vertisol type clay soil in central of Morocco. The results showed that besides resistance of Vertisol under NT to slow wetting test, the soil could resist also of the fast wetting test (p-value = 0.02 0.05). The results obtained in this paper have shown favorable effects of NT on the physical quality of the clay soil
