Subsurface Porous Pipe Irrigation with Vertical Option as a Suitable Irrigation Method for Light Soils

The main aims of current study are testing a new idea of vertical installation of porous pipe instead of horizontal installation, leading irrigated water down according to root depth, minimizing evaporation from soil surface and preventing deep percolation. This system was designed for three lengths of porous pipe (30, 45 and 60 cm) with three water heads of 2, 4 and 6 m and for a maximum irrigation duration of 300 min. The experimental results showed vertical expansion of soil moisture to the extent of 200% of porous pipe length in all treatments. However, acceptable horizontal expansion of soil moisture was recorded only for application of 6 m of water head. The produced soil moisture content by this system was shown in a range between 14.8 and 17.4% (w/w), which is around field capacity water content. Therefore, it can support plant growth in effective manner.
