Abstract EN
In Morocco, conservation agriculture, particularly no tillage systems, has become an alternative strategy to mitigate land degradation caused by conventional tillage in semiarid to arid regions.
This paper is based on behaviour to tillage treatments of two Vertisols in Morocco.
After 11 years of testing, soil organic matter content results showed a significant difference ( P < 0.05 ) only at soil surface (0–10 cm) in favour of no tillage and a variation of 30% at this depth.
The results obtained after 32 years of testing showed a significant soil profile difference ( P < 0.05 ), up to 40 cm under no tillage compared to conventional tillage, and a variation of 54% at 5–10 cm.
For total nitrogen, there was no significant effect between no tillage and conventional tillage at the soil surface after 11 years unlike the result obtained after 32 years.
There are no significant differences in bulk density between tillage treatments at soil surface for both sites.
The measurement of soil structural stability showed a significant effect ( P < 0.05 ) for all three tests and for both sites.
This means that no tillage helped Vertisols to resist different climatic constraints, preserving environmental soil quality.
