| Abstract | ||
| With the desire for horizontal and vertical expansion and the exploitation of new areas in the field of soil reclamation, and in most of the new reclamation areas, salt affected soil are spread. Salt affected soils can be defined as soils with high concentrations of dissolved mineral salts in their profiles such that these dissolved salts adversely affect crop production. Salt-affected soils occur in all continents and under almost all climatic conditions. Their distribution, however, is relatively more extensive in the arid and semi-arid regions compared to the humid regions. The nature and properties of these soils are also diverse such that they require specific approaches for their reclamation and management to maintain their long term productivity. For any long-term solutions, it is, therefore, necessary to understand the mode of origin of salt-affected soils and to classify them, keeping in view the physico-chemical characteristics, processes leading to their formation and the likely approaches for their reclamation and successful management. EL Hosainia plain area was chosen to study the effect of some agricultural practices as Tillage treatments ( 0-20,20-40.40-60) and Irrigation treatments ( 70 % of water requirement, 80 % of water requirement, 100 % of water requirement, 120 % of water requirement ) It was found that there is an improvement in the physical and chemical properties of the soil and a decrease in the percentage of salts in the soil with the increase in the depth of tillage , for example, the bulk density decreased, the porosity of the soil increased, the hydraulic conductivity of the soil improved with an increase in the depth of tillage and the rate of irrigation, and the pH of the soil decreased with the decrease in the percentage of salts in it and the improvement of the efficiency of use water | ||
