Abstract:
The objective of this study is the improvement of physical, chemical and hydrodynamic properties of sandy soil and valorization of the mud. The experiment is made out in pots of vegetation with increasing amounts of the mud and in presence of a barley crops. The results show a remarkable effect of the mud on the sand amended compared to the control. The addition of the mud to sandy soil increased the holding capacity and the useful reserve and decreased the infiltration. The improvement of the hydrous properties resulting from a reduction in the macroporosity and increase in microporosity as well as the improvement of the fertility of soil, have a direct consequence on the development of plant. Indeed, the growth of barley (height of stem and tiller number) and dry matter yield are clearly improved according to amounts of the mud. The EC of the soil increases slightly with the increase in the amounts but it is not significant except with the treatment 100% mud. Through the statistical results, the treatment 15% represents the best amount.
