Etude de certains paramètres de durabilité des systèmes de production céréaliculture-élevage dans le contexte de l’intégration des techniques de l’agriculture de conservation

Abstract

To plan out the place that will be optimally occupied by the animal production at this farm, in the context of conservation agriculture, we carried out a primary research of the effect levels of mild to moderate optimal stocking rate while grazing practice in farm taken as a test case in not worked plot of land (semi-direct) on some physical parameters of soil fertility. We found that there is an acceptable effect on soil structural stability and had no significant effect on the saturated hydraulic conductivity, the bulk density, the true density, the total porosity and vegetation cover, that when comparing their effect with an ungrazed plot of land containing a percentage of vegetation covers equal to 78%. We can therefore suggest that grazing with mild to moderate optimal stocking rate during the practice of direct seeding did not negatively affect the studied parameters. This research should consider other scenarios where levels of charges would raise more in order to deduce much more general conclusions.
