| Abstract | ||||
| In Egypt, the Nile Delta represents a large area of heavy clay soils with low permeability that might have a potential production. These soils are always threatened by a shallow saline groundwater. The main experiments were carried out to study the effect of drainage process and different drainage systems on productivity, physical and chemical properties of the soils of Earthen Delta. Three different drainage systems (unfilled mole drains, gravel filled mole drains and pipe drains) were designed and installed to select the suitable system for clay soil compared to without drainage (control). It could be concluded that the combined treatment of 4m spacing gravel field constructed mole with 40 cm depth (4F40) was the best treatment and should be recommended due to a relative high net profit comparing to other gravel filled mole treatments. On the other hand, the combined treatment of 4m spacing unfilled moles with 40 cm depth (4UF40) achieved the highest net profit comparing to the other drain treatments. | ||||
