General Price List | January 2022 | 59 DRIP IRRIGATION CLASSIC PRESSURE-COMPENSATING DRIPLINE FOR SUBSURFACE IRRIGATION - MULTIBAR™ C ROOTGUARD™ DISCOUNT GROUP 0105 SUBSURFACE SYSTEMS What is subsurface? Traditional “drip” irrigation systems using driplines are found above the ground. Now, with ROOTGUARD ® technology, the lines can be buried below the ground surface for a long, trouble-free life, without drippers being clogged by the root area. Subsurface allows the precise application of water, nutrients, chemicals and other agrochemicals directly to the root area of the plants, thus reducing the volumes of products used, resulting in reduced costs and environmental impact. This allows users to optimise the crop growing environmental conditions and leads to higher quality and quantity of yields. A system created using ROOTGUARD ® technology conveys water by capillary action down to a depth of 10 to 75 cm beneath the surface, forming a continuous wet area along the plant rows. Frequent irrigation cycles maximise the capillary action and minimise water surfacing. The depth and placement of the driplines depend on the soil composition and the crop needs. Focusing on product quality, reliability and ease of use, Irritec with ROOTGUARD ® provides the most advanced subsurface technology available on the market today, guaranteeing the best results. Particularly beneficial for loose soil with little gravel on flat or sloped surfaces. N.B.: the product contains synthetic chemicals for weeds control Why subsurface • 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 minimizing chemical environmental pollution. • Less weed. 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 pipes 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. No sprinkler heads, pipes or 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 ® subsurface 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 ® technology together with its popular MULTIBAR ™ driplines.
