CLASSIC PRESSURE COMPENSATING DRIPLINE FOR SUB-IRRIGATION ROOTGUARD Why sub-irrigation • Higher yield. The water and nutrients distributed directly near the root zone favour healthy plant growth and reduce stress. • Better quality harvest. Both soil and foliage are kept dry, reducing fungal diseases caused by surface irrigation and eliminates fruit and vegetable spotting commonly caused by overhead irrigation. • Safe and efficient delivery of fertilisers and insecticides. Chemical products are directly applied to the root system, reducing the quantities needed and limiting chemical environmental pollution to the minimum. • Fewer weeds. A dry soil surface reduces weed growth. • Better soil aeration. Fine soil particles are not washed down, thus decreasing soil compaction and improving root growth. • Dry soil surface. With a dry soil surface, cultivation and harvest operations can take place while irrigation is operating. Lawns can be used also during irrigation. • Longer irrigation system life. The turbulent flow drippers and tubing are made with high quality raw materials. When placed underground, the system is protected from damage caused by ultraviolet rays, temperature fluctuations and cultivation operations. • Considerable water savings. Elimination of leaks due to evaporation, deep percolation, superficial flowing and displacement of damp due to wind. • Less vandalism or mechanical damage. driplines on the surface which can cause damage or which are subject to damage by vandals, animals or harvesting of the plot. • Less salt. • Less water also means fewer salts in the soil or the aquifer. • Lower maintenance costs. • The system is installed permanently below the crops and does not require further handling. • Less chemicals. Fungicides and insecticides are not washed off by irrigation water and the direct delivery through the system reduces waste. • Labour savings. Easier fertiliser application, less weeds, disease control and less maintenance mean less labour. • No obstacles during mechanised harvesting (vintage, use of shakers, olive cultivation). • Nicer orchard design because tubes are not visible. Installation ROOTGUARD® sub-irrigation system uses the same components of a surface drip system, including filtration and treatment of water, fertiliser and chemical injection, air release valves, discharge valves and manual or automatic control. The only and most important difference is the dripline manufactured with ROOTGUARD® technology. Today Irritec supplies ROOTGUARD® MULTIBAR® driplines. For the hydraulic characteristics of each dripline please refer to the respective technical catalogues. technology together with its popular No sprinkler heads, tubes or Typical outline of a sub-irrigation system The installation and use manual is available on request of the ROOTGUARD® sub-irrigation systems, which can also be downloaded free of charge from the website www.subirrigazione.it Furthermore, our technical office can provide the technical support necessary to design and install the ROOTGUARD® system. 2019 | drip irrigation catalogue | 41
