However, the agricultural soils support largest constraints, which are the salinization, the hydromorphy, and the exaggerated division of the parcels by successive inheritance what can provoke a decline and a reduction of the productivity. The sampling and the analysis of the irrigation water shows a net rise of the waters salinity, of the order of 5.25 g/L.
