dc.description.abstractConventional agriculture practiced in Morocco based on recurring tillage, leads to soil degradation (erosion, fertility diminution, low organic matter content, etc.). 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). A significant effect was observed for the SOM content at the surface (p-value = 0.00 < 0.05) whereas, there is no significant difference for bulk density (p-value = 0.08 > 0.05). The results obtained in this paper have shown favorable effects of NT on the physical quality of the clay soil. L’agriculture conventionnelle pratiquée au Maroc, basée sur le labour récurent, conduit à la dégradation des sols (érosion, réduction de fertilité, faible teneurs en matière organique, …etc.). Pour faire face à cette situation, l’agriculture de conservation offre une opportunité pour renverser cette tendance alarmante. En effet, plusieurs travaux ont confirmé le constat positif de l’agriculture de conservation vu son influence sur la stabilité structurale qui est étroitement liée à la teneur en matière organique (MO). Ce travail contribue à mettre l’accent sur l’impact du semis direct (SD), après dix ans d’essai, sur la stabilité structurale, la MO et la densité apparente (Da) d’un sol argileux de type Vertisol au Maroc central.Les résultats obtenus ont montré que, en plus de la résistance du Vertisol sous SD au test d’humectation lente, le sol a pu également résister au test d’humectation rapide (p-value = 0.02 < 0.05). Un effet significatif pour la teneur en MO (p-value = 0.00 < 0.05) a été observé à la surface du sol, alors qu’il n’y a aucune différence significative pour la Da (p-value = 0.08 > 0.05). Ceci a permis de montrer les effets favorables du SD sur la qualité physique de ce sol argileux.en_US
