Abstract: Irrigation is necessary in a dry climate, in which natural rainfall does not meet plant water requirements. The total concentration and the concentration of the more important constituents must be determined to judge the quality of the water provided from surface water or from groundwater. The soils information must be given in as quantitative and exact a manner as possible. The following soil data will be required: hydromorphic soil properties, permeability for water, moisture storage in the soil, data on salinity and alkalinity, soil mapping units, external factors. Gleysoils and Salsodicsoils cover about 30 % from the surface. The objective of the scientific research was to establish the possibility to re – use of drainage water to irrigate areas adjacent to the region where it originates from. The area is highly unbalanced due to the numerous meanders, old watercourse and river branch of Timiș, Timișul Mort, Bega veche. The majority of soil types present low salinization but the alkalization process is strong and the salsodic subtypes are dominantly. If we consider the area with sodic / salinic soils then the surface reaches 30 % from the territory. The water from the draining canals can be used for irrigation because the quality of this water is very good, or even excellently. In area with sufficiently water provided from the draining canals, reclamation of sodic soils can be obtained by leaching the soil with successive dilutions of high – salt water containing divalent cations.
