CLASSIC PRESSURE COMPENSATING DRIPLINE FOR SUB-IRRIGATION ROOTGUARD Product certified ROOTGUARD ® according to ISO 9261 SUB-IRRIGATION SYSTEMS What is sub-irrigation? 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. Sub-irrigation 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® /B n. 200 ISO 9261:2004 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 sub-irrigation technology available on the market today, guaranteeing the best results. Field of application (cf. page 3) Sub-irrigation Particularly beneficial for loose soil with little gravel on flat or sloped surfaces. N.B.: the product contains synthetic chemicals for weeds control Sub-irrigation Surface irrigation Distribution of water after 10 hours with 1 hour of irrigation Conveying the same amount of water, drip sub-irrigation covers a 46% larger wet volume of soil than a surface irrigation system. This decreases the saturation point of the soil, not only leaving room for more air, but also improves the capillary movement of the water and decreases water loss by percolation. 40 | drip irrigation catalogue | 2019
