PFRA Shelterbelt Centre Publications PFRA Shelterbelt Centre Publications Drip Irrigation For Farmstead Shelterbelts Trickle or drip irrigation is a controlled method of watering that makes efficient use of available water. It is a method that holds promise for use with shelterbelts, particularly in the establishment of conifers in drier areas such as southern Saskatchewan. The system delivers the water required by a tree seedling, drip by drip, through a small emitter in PVC or polyethylene pipe to an area directly around the plant. The plant can then use the water with little water loss to seepage or evaporation.
Drip irrigation is suitable for a wide range of soils and topography.
The head of the system is composed of the water source, pump, filter system, pressure regulator and necessary pressure gauges. It may also include a water meter or electronic controller. The distribution network includes the mainline and laterals or dripper lines located down the plant rows. A study evaluating a typical drip irrigation system was initiated by the PFRA Shelterbelt Centre, Indian Head in 1985 because of increased interest in this irrigation method. A pressure regulator valve maintained pressure at 20 psi to deliver the desired flow.
