dc.description.abstract In salsodic soils which are located in arid and semi-arid areas, the agricultural management of water is a key element to the protection of the agricultural system in light of the state of degradation and quality of water irrigation. In this case, land use requires a special interest because of its impact on all the physico- chemical and biological processes that govern their operation. The present work is a physic chemical approach to health parcels of land that is subject to different uses. Four salted plots has been worked and amended on through gypsum 0,7500, 15000 and 30000kg.ha-1 are being considered. In addition to three others that are kept unworked. The results of this study show that salinity affects deeper layers, from the surface layer of the studies soil. Undistributed ground seems to resist to the phenomenon of salinisation\ sodisation worked from the ground because of human act. 3 The indicators of the physical state of the land which are ordered according to their importance and adapted in the studied site are: the stability of the structure, l'ESP, the ceeps, the SAR and the ionic checking. en_US
